Hi, ive bought a new loom for my fuel pump, it says to look for a thin blue wire with a black stripe



But this is the only yellow relay i can find next to the ecu, this is blue with a green stipe



Can anyone please help??

Also would you remove all the old fuel loom wiring or just disconect it?

I've just bought a fuel pump loom mate and didn't have any instructions with it, but i did find this thread that may be of use to you

There's a link on the 5th reply down that leads to another thread aswell

Also there isnt a thin blue with black stripe wire going to any pins on the ECU, can anyone shed some light on this please?

just pin out the trigger for the fuel pump relay and use that to power the new loom.

adam151082

How would i do that? Do you think thats the fuel pump relay im holding?

James @ M Developments.

iTrader: (2)

only you can answer that by carrying out some continuity testing, the ECU will power the fuel pump relay from pin 28, this should connect to your new loom and supply the trigger for it.

Either that or leave the old relay as it is, and use the old fuel pump feed to trigger the relay.

Get a multimeter on the job, does the relay you are holding have a trigger with contnuity to pin 28?, and continuity to the fuel pump via the main live output? if so thats the fuel pump relay.

If you get stuck with it mate i am back home next week and i will give you a hand. Alternatively you not have a Haynes manual, there maybe variations in wire colours which should be listed in the wiring diagrams at the back.

Who did you get the loom off out of interest to recieve crappy instructions like that?

adam151082

Ill go out and have a look, so im looking for the wire that goes to pin 28?

Cheers Paynee, i havnt got a haynes manual. Ill get in touch if im still stuck thanks

The instructions would of been spot on if the wire was there, could be that sombodys messed with my loom.

James @ M Developments.

iTrader: (2)

i was thinking the same

Mr RS500

iTrader: (6)

He got the loom from me mate


My supplier included the instructions

I dont see whats crap about them as everyone else i have supplied these looms to ( and i have sold a lot ) has never had any problems

I even fitted one to my own rs500 today and managded quite well

Mr RS500

iTrader: (6)

Says the company who supplies new fan looms that you have to cut the old fooked plug from your own loom to use with a new loom

You could always buy a quality item with a new plug and sensor provided

if you cant work it out give me a ring and ill help you mate

iTrader: (21)

Is it just me, or has this place got even more argumentative than usual, recently?

James @ M Developments.

iTrader: (2)

Not sure what your on about? My point was regarding the instruction being poor, i think anyone reading or looking at them would agree TBH.

Ours come with comprehensive instructions the end user can understand, the ones supplied here obviously dont work, hence the op not knowing how to fit the supplied loom

RE the comment on our loom, An OE plug and sensor? or one that was from a different car? im sure we could easily do the same if we chose to, but the operating tempertures of the escort cosworth fan switch were not what we wanted.

Mr RS500

iTrader: (6)

What has escort cosworth got to do with my looms ?

This is the first time i have ever had anyone struggle with finding the fuel pump trigger wire , Adam obviously isnt the best with electrics so he has done the right thing and asked

If we thought " comprhensive " instructions were needed then we would give them , Maybee ill ask my man to do this ,

Love the reason for the old plug required on your looms ,,,quality,, but it has given you an excuse to try and knock my looms hasnt it

Anyway , I leave it there James , I would hate to say anything against MSD just to try and make my products look better

rog

iTrader: (2)

Well first up can you confirm it is a 3dr, and does it have the standard wiring loom it in?

coswurv

iTrader: (8)

I just think the instructions look rubbish, not sure why you would want to pick the trigger wire up from the ecu end rather than just cutting the fuel pump pos feed at the rear and pulling it into the spare wheel well, crimp on a insulated spade and push it on the relay.

Mr RS500

iTrader: (6)

Are you being serious ?

As for the instructions , Im happy for constructive comments , this is the first time we have had anyone struggle and we have sold hundreds , saying that im sure my supplier will be happy to make them better if it is required . But to just say there rubbish isnt realy a great comment ,

Maybee i will ask him to copy MSD and do a " comprihensive " fitting guid to cover all cars with all looms

Maybee we forget that finding a trigger wire isnt as easy as we find it to be for some folk

James @ M Developments.

iTrader: (2)

Me "knocking" your looms? My comment was to do with the instructions. Not even knowing it was one if "your" looms mate.

I think if you re read the above posts you will see it was you having a dig at our looms.

As for quality, I've never seen or used one of your looms to my knowledge so I have no idea why you think I would " knock" them, for all I know they may be made by the same people.


So Paul by using the std trigger to power the new relay does the fuel cut off still work? Designed to prevent the fuel pump running if an accident occurred? As that was the main reason we advised the std fuel pump feed was used to trigger the relay.
We deemed it pretty unlikely the oe relay would fail with such small current running through it if it was used to trigger the new loom,
And also that the alternative was to try and explain how to re wire and use the fuel cut which would have been a nightmare.
Not a dig, just wondering how you got around it?

adam151082

Thanks Paul, ill ring tomorrow.

Well I am being serious, I think they could be a lot better, I don't use msd products so can't comment on their instructions. I just think from experience it's so much easier to pick up the trigger wire at the rear by using the old pump feed, this wire is only a trigger so as long as there's continuity it will be fine. Lets be honest all the the new loom relay etc can be neatly installed in the spare wheel well, out the way, plus I normally mount the new relay to the fuel cut off housing which gives quick acces to retaining the cut off switch.

Mr RS500

iTrader: (6)

The point of the new loom is to remove as much as possible of the old corroded wiring

by simply pulling it through the boot floor you are still using 95% of the old corroded wiring

coswurv

iTrader: (8)

Well your not are you, its just a trigger wire as stated, all the rest is brand new to the back, if that was the case even your loom still uses (old wiring) that could break down, the same as using the feed as a trigger as i said, you still have old ford wiring coming from batt to ecu plug, then to the fuel relay which again is all old. Anyway im not getting into row, just my opinion and experience in what ive always done.

Stu @ M Developments

I think you need to take a deep breath Paul, I don't see James bad mouthing your looms, just commenting on the hand written comments in the instructions.

However, i do see you bad mouthing ours. LOL

James is right about the connector, you cant buy the OE one anymore. Any you know that, as you change yours don't you? The reason I didn't do that is very simple, if you do that, how can people fit a new fan switch when their fails? the correct sensor will no longer fit the loom... or have you found a solution?

James comment about the fuel pump safety switch is a valid one. What are you doing to keep this safety feature in service?

The best thing to do with the fuel pump cut off switch is to replace it with an escort cossie eec4 one and relocate it as per the escort cosworth and wire it through pin 28 of the ecu which is the fuel pump relay earth trigger not a live trigger as previously posted by someone
To the OP that is the fuel pump relay you have in your hand and pin 85 of the relay is the ecu activated earth switch which goes to pin 28 of the ecu

Stu @ M Developments

iTrader: (12)

Or fit a decent rear axle.

roflol
and some decent shocks
and make sure you fit the spare wheel retaining bolt

Stu @ M Developments

iTrader: (12)

And take the "RS emergency kit" out too...

IE: The 12 spanners, 6 screwdrivers, 4 rolls of tape and assorted length tiewraps and the 9 spark plugs (all different) that are rolling around in the wheel well with a gallon of rusty water...

adam151082

Ok thanks for the help guys, a 2min talk with Paul and i was sorted.

My next question would you remove the old wiring or just remove the power from it? Im in two minds

costina

iTrader: (1)

Ive never taken any tools with me best i do next now ive said that
INC gaffer tape

costina

iTrader: (1)

Leave it more hassle than its worth Just dissconnect the live to it

Mr RS500

iTrader: (6)

The " solution " is more simple than you could ever imagine Stu

you simply buy a replacment switch that is exactly the same as the one supplied with the new loom

Stu @ M Developments

iTrader: (12)

If you tell them exactly what that is on the invoice when they buy it, then that's fine mate, I just assumed you didn't and the customer would be stuck if he couldn't get hold of you personally to find out.
Meanwhile his car was left in a dangerous condition and likely to overheat. Obviously I assumed wrongly, so my apologies.

Mr RS500

iTrader: (6)

I could reply to this in a simular sarcastic way stu regards your looms but wont

I have sent a pm rather than carry this crap on anymore

Stu @ M Developments

iTrader: (12)

It wasn't sarcastic. If you don't know what the switch is when your car overheats miles form home in a jam and you need the RAC to bring you one, you cant just:

Can you? Its you who said they can, and why I appologised for my assumption.

If your saying you don't supply that info then in fact YOUR REPLY above must have been the sarcastic one aimed at me then must it not?

And to think its you who started this by taking the piss as my looms are designed on purpose to retain the OE sensor fitting for ease of sensor replacement by the end user. Why did I bother even replying? LOL

Turbosystems

iTrader: (5)

and join the RAC
the car new came with 12 months free RAC cover
see ford knew

Stu @ M Developments

iTrader: (12)

I bet the fucking RAC lost out on that deal..

Mr RS500

iTrader: (6)

And ours are designed exactly the oposite as we wanted to get away from the brittle 20 year old plug that 95% of the time has the clips that hold it onto the sensor broken of

we wanted a new plug with the more modern but secure quick release clip and new style sensor as we also thought that the old style could possible be obsolite soon

so our aim was to provide a new loom with modern switch and plug " that can be bought over the counter at ANY motor factors .

I dont see your point about being stranded as our new sensor is actually easier to find than the OE item if stranded

anyway , enough said as we can go on all night trying to say " mine is better than yours "

Let the customers decide

You have a great reputation for quality items and fantastic customer service

I do in some eyes and not in others , lol , but im not dependant on parts sales anymore but sell these looms as IMO there a great product and a great price

Stu @ M Developments

iTrader: (12)

How can it be, if you dont know what it is your trying to buy?

Totally agree. Its a daft argument started by some writing on a piece of paper. Horses for courses, we all do things our own way and as long as the customers happy, I am happy.
