Wiring 2.5 SOHC into BC Legacy

[BLSTIC]

Hey y\'all. Latest screwed up wiring mission. A mate has requested that I wire his speedway car. It\'s a BC(some number). Either way it came with an EJ20 DOHC, and it\'s the first generation legacy sedan. Not that that really matters because there ISN\'T A SINGLE SUBARU WIRE REMAINING except for the half engine loom that\'s on the 2.5 SOHC (out of a 2000 Liberty).

I say half loom because it has the engine loom, but cut before it all joins to go through the firewall (so the injector resistor pack and all that stuff isn\'t part of the loom).

What I do have however is the COMPLETE loom (tail lights, fuse box, everything) for the DOHC EJ20 that was originally in the car.

So should I just start with the old loom and try make it fit, or start basically from scratch? I assume the only difference is with the coils, as the EJ20 has coil packs on the head and the EJ25 has the wasted spark system. Unless the BC didn\'t run sequential injection? The wiring diagram I have for the EJ25 implies that the later ones do.

If it helps it\'s all going to be plugged in to a Link G4 Storm. So actual computer/crank angle sensor compatibility doesn\'t matter, just the plugs and wires.

Long story shortened: I have mangled and half gone loom for the correct (EJ25 SOHC) or complete loom for wrong engine (EJ20DOHC). What should I use, given I\'m using aftermarket management and the EJ25

I\'d use the complete loom and hack it where required.

Anyone know if the crank/cam angle sensors are the same? If they are I\'ll just use the old loom, and ADD the ignition part of the \'correct\' loom. Because he\'s going to build a 2.5 DOHC for it...
