wiring all mine into the erst (frst loom)
i have 3 spare trianguler connectors is this correct were do they go or what they for??

cheers

 

hi mate dont no if he can help but pm 1.9 xr2 on 40's as i no he done efi conversion on his series 2.

 

chhers hopefully he will see this post

 

 

2 digonistioc contoctors (spellig) white black taped 2 gether and possibley a speed sencor wire

 

That's exactly what I was going to suggest. Not sure if it's the same on a scort but on a Fiesta the two diagnostic conns (a white and a black plug) come down to the battery area - front n/s of the engine bay on a scort where the MFi metering head would go. The other connector comes down between the inlet and the brake servo.

If you're still stuck, list up the wire colours of the plugs.

Can you tell which ones it is from this pic of mine ?????

 

pm gadget im sure he will br able to help ya

 

the 2 black with red plugs in are diag ports as said above

if the other comes off by the EDIS module it is for the speed sensor

 

cheers

so speed sensor whats that for?? or were does that go?

 

is the one for the Crank sensor the one that right on its own with alon bit of lead with a plastic sleeve at teh end of the connector? i take it???

 

Crank sensor is on far bottom left. This one is critical so make sure the insulation is good and the wiring has virtually zero resistance between the plug and the connection at the E-DIS module or ECU (can't remember which but fairly sure it comes down to the E-DIS).

Any EFi/CFi/SEFi injection speed sensor can be used - it loves on top of the gearbox where the speedo cable screws in and the cable then screws into the top of it, and it's used to keep engine revs up while moving along (supposed to make low speed driving smoother) - it's not vital for the engine to run well.

Last point - make sure you use the FRST inlet air temp sensor - it uses a Weber (injector-style) plug instead of the Ford one used on the ERST and n/a engines - if you've got the wrong sensor, your engine will run pretty flat as the ECU will retard ignition far earlier than it should.

ok cheers whats the one on the far botom right then??

 

Would try and use an EFi XR3i loom mate if I were you.

shouldnt be no different mate frst just as good

 

How you gettin onwith track car Roosie.

 

It is but locates the ECU in a real awkward place. The EEC ECU's are not weatherproofed like the original RST ECU's.

It Also means you have to splice the ERST loom of its wiring.

Thus leaving a dodgy looking engine bay.

However, your right, it will work.

ama ,and EDIS earth- make sure this has a good earth, or the car won't spark!

 

its more or less done lee just need this loom wired ie the 8 wires togot the relays ect

im putting ecu in same place were old one was

 

AMA???????????????

 

amal, soz!

 

i mean on that pic rolls amal aint that one!!!

 

mine is xr2i loom im mk4 escort

 

it defo looks like the amal, with the oil pressure sensor next to it, and the map, and co2 pot above it...... above that is the ISCV connection...............

 

deffo the amel 1, called a 'boost control valve' in the haynes


on mine the ecu is tucked behind the battery
works but not ideal, in the car via a xr3i efi loom would be better, when i done it, it was just to get the car mot'd and i didnt have a erst lump to hand but i did have a frst 1
mite go back to erst when this lump blows, which im sure it wil

 

Hope this helps you mate:

Project ST,

Yes, them loose wires are for the immobiliser, removed now.

 

thats all sorted cheers mate

 

the speed sensor actually leans off fueling at certain revs according to simon @ SECS tho

dunno how true this is

but it was meant to be there so i let it be
