B18C7 into GSi

[aldo10]

Cheers RC. It's a July 96 build. As you said, the other wires run into cab loom. Just need a few hours of spare time which is always the issue.

I'm curious if some of the links I find are applicable to my vehicle. This link has one of the only pics which has a similar ECU to mine with reference to layout.

Interestingly 8(Vtec solenoid) 15(Vtec pressure switch) and 6(knock sensor) are not wired on my chassis harness. The are all blank at the plug.

Does anyone here agree with the plug layout?

B18C7 is OBD2a so just search for OBD2a ECU pinout (the one in the link is correct)

There aren't any wires in you chassis harness because it's a GSI chassis, just extend the wires from your engine harness to the ECU. Pretty straight forward, but you will need ECU connector pins for a clean job.

Ok thanks. The company in the link above sells pins. Are there OZ based sellers? I've tried eBay with no luck. $1.30 pins with excessive postage from the States on the bay.

Just go to the wreckers and cut one off

My power steering hose leaked over my new belts. Bit of a setback I didn't need. It leaked at the joiner which holds the restrictor. Getting it repaired and back into the two clips and rubber holder/saddle clamp was a right pain. All down and now back into this ECU and wiring. Can't see an end to this lol

Hahahh. Sorry but reminded me of my build. My bro forgot to reattach the vtec solenoid before starting the engine. Gave the entire engine bay and the garage wall a nice lube job :P
Edit:
+1 for extending for ecu. Or buy another loom

c7 swap

what a time to be alive

nice thread tho man was entertaining haha

Lol yeah I'm a couple of decades behind.

Well it's finally finished! I think lol. I wired the VTEC solenoid up and tentatively took it for a run and it certainly works! It's been a while lol. Anyway thanks to everyone who offered assistance, it certainly kept the project rolling. With kids at school and full time work etc it's certainly steady as she goes, nothing happens quickly as spare time is a luxury.

Anyway cheers I'll try and get some pics up after I wash 7 months worth of dust off the bodywork.

Ok I've managed to put around 200ks on it now and it's all running sweet, no funny noises, no smoking, air cond, steer etc all great except it throw the engine light up every time it hits 2500rpm. Stopping the engine turns it off and restarting it the light is out. Hit 2500 rpm and it comes back on.

Any ideas? Any preferred mechanics on Brisbanes Northside?

Pull the code from the ECU and you'll know which sensor is throwing the code. The old paperclip trick usually works if you don't have a scanner or an aftermarket ECU. If you have an S300 just plug your laptop in.
