V3/4 Engine loom schematic

[Guest]

After the schematic showing all sensors etc to loom.

Cheers

Haha, me to. Best I found so far is this but it doesn't tell me which plug perspective it is from.

You got another project on the go or you buy a v3/4 g4+ to wire up your legy?

[Jono24]

Just the link v3/4 for the legacy, realised yours might be a bit more significant once I posted it.

[Guest]

Ive got the link pinout just like to know where each wire goes to or what it links in to as im converting to v7 sti manifold/avcs.

Be a bit of wiring in your one dude.

It's less than ten wires between mine and v7, let me know what you find, I'll be interested.

Im figuring i can use iacv wires for idle solenoid, tps for tps, map for map and iat for iat providing it has iat wires present. Then just need to wire up coil packs for wasted spark and avcs side of things.

Here's the V3/4 WRX engine wiring diagrams:

Certainly can. Any unused signal wires for either sensors or solenoids can also be reused, eg:

Purge control signal - AVCS solenoid left bank signal

Pressure change solenoid - AVCS solenoid right bank signal

Then here's the OEM ECU pinout, so you can transfer the link G4 V3/4 plugin pinout numbers over to see exactly where they all go:

Precisely what I was after thanks Ross. I did peruse that thread but somehow missed that link.

Yep thats what I did last time with the plug in think Ill run a second loom for cop/avcs as I have a complete loom to cut it out of then connect back at ecu.

I got my loom adaptor 95% finished, it's a bit of a spaghetti monster!

I've got a complete v3/4 manual if anyone needs, it is a scan so it's not searchable, but still useful.

I would love a copy.
