Hi i got a erst s2 with a efi conversion using frst ofac ecu and ive been following this diagram taken from this site



i took the ignition live from a yellow wire inside the car where the radio plugs in.

So then i started the car and all was fine until i turned the key to the off position and pulled the key out and it didnt turn off and i got scared . I had to stall the car to turn it off. what did i do wrong?

 

this yellow wire, are you sure it was a ignition live that you joined it too and not a constant 12v feed?

ive followed this diagram and had no problems so i know this does work

 

hi rst ski

im not sure i just thought it being yellow and it being on the radio multiplug it might be a ignition live

 

worth double checking with a test light dude

i used the original ignition feed that goes into the purple fuel pump relay on mine

 

what colour is the wire for ignition live on the purple fuel pump relay?

tell me please, please, please

 

cant remember to be honest dude

you not got a test light/probe?

 

ive found a multimeter so i will use that. aleast you've pointed me in the right direction for a ignition live on the purple relay

 

Just one thing........... a purple fuel pump relay with EFI......???!

 

no using efi relays but using the original feed that went into the old purple fuel pump relay

 

Hi safechav

im using a frst injection relay and fuel pump relay. I got the ignition live bit wrong in the diagram. So causing the car not being able to switch off.

but hopefully il get this sorted 2moro with a ignition live wire from the purple fuel pump relay with a inline fuse aswell just incase to be safe.

 

You'd be better off taking the ignition feed from the switch wiring itself, its a lot thicker than the one on the fuel pump wiring.

 

wont make a difference, mines been ok for ages

 

What sort of current are you pulling through it??

Baring mind the tachometric relay that once lived there will only pull millamps

 

duno, but the set up is tried n tested now so good enough for me

 

If you look at the diagram the switched ignition feed originates from the switch itself!

Fair enough if yours is ok, wouldn't risk meltdown myself though

 

safe chav
you got me worried doing the fuel pump relay way now but in the diagram it doesnt run a fuse so i guess a wire from ignition switch is fine and i wont risk anything is this correct?

 

im confusing myself now

What have you wired wrong currently? The switched feed for the wiring multiplug for the OFAC loom?

 

Sorry i havent been clear safechav

ive wired a wrong switched feed for the wiring multiplug for the OFAC loom

 

im sure somthing would have happend now in 8months so im not botherd

 

you want to connect that directly to the ignition wires IMO, or use the redunadant wires in the loom from the old management.

i wouldn't worry about a fuse, all the main ignition feeds are unfused, but it won't do any harm if you want to play it safe
