I probably read more than 4 thread this month about this topic. Im in the same situation right now and even I know that if you search you will find the answer. The answer to your question is Yes. You need to send your engine harness to rywire so they can modify it.

Umm... wrong. You only need to send it to them if you want them to wire in the fan switch entension and obd1/2 injectors (no resistor box) etc.

1990si: Yes, that's everything you need. You'll need to extend the wires for the fan switch. I would suggest keeping your obd0 injectors and resistor box for ease of installation.

 

well I thought he wanted to conver to obd1.

 

i do want to convert to obd1. can i still use my obd0 injectors and resister box on the z6?

 

You will need the following if you dont have it already.

obd-1 harness
obd-1 injectors
d16z6 distributor
obd-1 ECU
4 wire oxygen sensor

From the obd-1 harness, you will need a couple plugs.

1.All 4 injector plugs
2.Oxygen sensor plug
3.Fan switch plug
4.Vtec Solenoid plug
5.Vtec pressure plug


My friend made his car obd-1 and used the obd-0 injectors and customized the harness at the resistor box so that the injectors were getting 12 volts. He had to cut a small piece of the inside of the injector plug because the harness would not clip onto the obd-0 injectors.

If i were you, do everything right and get the things that I wrote up at the top. Dont take any shortcuts.

 

well the rywire conversion harnness comes with all of that, doesnt it??

 

What you will get:
- OBD0 to OBD1 ECU Conversion Harness
- VTEC Subharness w/correct O2 Sensor, plug and play with ECU Jumper.
- OBD0 to OBD1 Distributor Adapter (OBD2 D-Series available upon request)
(O2 Sensor Not Included)

 

you dont need obd1 injectors just use your obd0 and keep the resistor box

 

ill just


get the conversion harness with all those goodies
get a 4 wire o2 censor
use obd0 injecters with resister
use a p28
use the z6 dizzy

That sound good?

And i will not need to use anythign off the z6 harness then, correct?

 

where is the fan switch plug located and where does it have to be ran to?

 

i believe its on the back of the block

 

quit thread jacking.
