You can either run your own wires from the ignitor up to the VVT coils, or you can use most of the stock 1.6 wiring by just deleting the ignitor, connecting a few wires, and then making all the other connections at the back of the head. There's no ground wire for the 1.6 coils (they ground through the head) so just ground the VVT coils into the head in the same way.

Bump!

Sav, I have a few questions for you. I just got an 01 engine yesterday, and it came with the entire engine harness.

My thoughts would be to use this harness and tie it into the current wiring harness I have (93 chassis) and run the extra wires I need (2 injector wires, vvt, anything else?) I was wondering though, You mentioned in the second post in this thread that you can keep the coolant temp stuff the same. Does that mean that I can use the 01 coolant temp sensor for both the ecu, as well as the gauge? Or do I need to retrofit the 2 wire temp sensor and single wire gauge sending unit?

I think you should also stick to Sav's severe suggestion to keep the old wiring - everything else will be a wiring job from hell (believe me I looked into it)

I followed Sav's advice and finished my engine bay rewiring last weekend. It was stupid, stupid easy.

Do it exactly as he says, thank him later.

Just use the VVT engine harness for the pigtails - nothing more. Don't try and blend the two - just use the VVT harness for parts. Cut the VVT, cam/crank, TPS, IAC, and coil pigtails off the harness. I sometimes use the injector pigtails too since they're usually in better shape than what you'll have on your '93.

You keep your '93 CLT sensors on the back of the head and ditch the fan thermocouple at the front (use your standalone to control the fans like a capitalist would). You may be able to use the '01 CLT and splice the wires correctly, but it may also require recalibrating the ECU and the dash gauge may not work, so it's not worth the hassle if you have known good/working CLT sensors from your current engine.

Hi, I'm a little confused about this step, I have a 93 chassis and trying to wire a vvt engine in. The 93 ignition coils have a 3 pin connector on it, what is the ignitor that I'm supposed to bypass?

Do i just wire up the vvt ignition coils straight from this 3 pin connector?

Thanks!

The igniter is on the passenger fender. Look in the COP thread for a picture with pinouts.

Thanks, I should've posted again sooner - we looked at that thread and worked from there. All the wiring is done now =D Tons of great info in this thread and from Rev.

We just cut the wires into the igniter and ran new wires to the coils, then ran the tach wire back to the ECU through the fender wall.

This is an old tread, but I still hope to get som answers.

Because of the strict regulations in Norway, I must present my '97 1,8 for inspection with the stock ECU from my '02 donor car after installing the vvt-engine. I can not install a standalone until the engine swap is approved.

Will it still be possible to use Savingtons approach when using the stock '02 ECU, or do I have to use the unfortunate method of splicingin the '02 engine wiring harness?

The job in the engine compartment would be very easy, but I assume the job under the dashboard is going to be agonizing and difficult.

Good advices would be appreciated

I think it would be easier to buy a patch harness to let you plug an '01 ECU into your '97 harness.

Thank You.
Do You know if it is possible to get a ready made harness for this, or will I have to alter the wire layout in the patch harness myself?

Would a stock 01 ECU allow the car to run without an immobilizer?
