Does anyone have a wiring diagram for 1994 WRX?

It relates to this:
http://www.pistonheads.com/gassing/topic.asp?h=0&a...

We are putting a (we think) 1994 WRX engine in a legacy. It is a 94 2litre turbo with 4 coils. We need all wiring diagrams relating to engine, ecu and power. Subaru are being no help at all. Does anyone have a relevant diagram that they could send us?

Thanks in advance.

Hopefully you've got a 1994 WRX ECU to go with the wiring loom. You'll need the clocks too but you'll have to faff about with some wiring mods to get the lights, indicators and wipers working, also somehow fitting the 94 WRX clocks into the legacy dash so you can see what's what, or by the sounds of it not if you don't need the clocks or any of the other ancilliary bits working because the car will never be on the road.

For 350 bhp you'll also need 550cc injectors, a TD05 16G or VF35,VF23 or VF22, 97/98 MAP sensor, 94 3-port boost control solenoid and MAF sensor, or you could run MAFLESS.

Tell you what...if you build this car with all the right bits and get it running off the std WRX ECU i'll sponsor you with remapping it Free Of Charge. All you need is an ESL daughterboard and you'll have one very quick shed!! biggrin

Edited to add: Run it MAFLESS on the above mods with 99RON fuel and a 10% Methanol mix and it will make an extra 20-40bhp when remapped.
