Help finding live feed to 4plug ecu?
Hi guys, need to find out which wire on a 93-96 ecu is the power feed to the ecu.
I have a wiring issue that i cant trace which is constantly feeding power to the ecu even when the key is out.
Going to wire in a switch as a temporay fix for now. And as Simon (jgm) said will double as a second imobiliser lol.
Any one got the wiring diagram and can point out which wire?
Last time i had a quick look it seemed to have more than one feed?
Thanks in advance

ive had a quick look at the wir diag for u (note - i am not an auto electrician.....! )
looks to be live feeds :-
15 on B43 - back up power (don't know what that is ?!)
10 on B96 - ignition switch
12 on B95 - ignition
there could be more - diagram isnt that easy to read................................!

I think its more going to be more like '2 on B43' and '13 on B43' labelled as 'Control module power supply'
But if i right with this which one do i wire the switch too? lol

I would have the car switched off, multimeter to hand and check which cable is constantly live and put the switch in the live wire. To do this you need to either find the 0v return of get a good earthing point from the metal frame of the car.
Hope this helps

Edit, I pointed out the switched 12V.
However, on my My98 ECU the 12v wiring is substantially thicker then the other wiring, so It could be easy to find with a meter (as you'll only need to check 4 or so thicker wires instead of all terminals on all plugs.)
