Been looking at a car that has burnt out the wires by having them trapped between the headers and the car..
they have fixed the burnt wires at the front but now..
Electric windows dont work, central locking doesnt work, no engine check light, and all that happens is car turns over..
Where to start??

The car is now stripped with no wings so I can go and trace some wiring...

Not much help David but although the wiring burnt out by the headers a short may have occured elsewhere due to the heat build up in the wires..

My sympathies. I can't think of anything but the obvious... I take it you've swapped the relays around, you've found both fuse boxes etc...
I suppose you get signals from the crank and cam sensors?
Do you have a pinout for the ECU? It must be pin compatible with the UK scoob one if you've tested it in your car, so if you don't have the diagram, I may be able to email you one.
Have you tried supplying the ECU with power directly (no solution, but may help indicate the fault?

Just looking in my workshop manual... (for pre 97 cars...)
(B43) pin 12
(B43) pin 13
(B43) pin 15
(B95) pin 12
Should all read greater than 10v.
Ground pins as follows:
(B43) pin 11
(B43) pin 22
(B44) pin 14
(B44) pin 15
(B44) pin 24
(B44) pin 25
B43 is a 22 way connector
B44 is a 28 way connector
B95 is a 12 way connector
B96 is a 16 way connector
HTH!

David,
I'm a bit confused, if it's an STi3 then it should have a 97/98 ECU surely?
I have an ECU from an STi3 and its the same as a UK one without the immobiliser circuitry.
