I just bought an 88 CRX Dx frame that had a D16Z6, so it had an obd0 to obd1 conversion harness. I believe it also had wiring modified on the engine harness for vtec and the change from DPFI to MPFI. What I am going to do is drop in a B18A obd0 from a 90 Integra into the crx. I would like to know if it would be easier and cleaner to take out the complete wiring from the integra and swap it into the crx and keep it obd0? I am planning in the near future to state ref and bar the car. Thanks for any help.

 

If it was a DX, it will not work.

 

keep the obd1

 

to answer the question, no you cannot use the integra harness, to keep it simple use your current harness, you know it works, then just get the correct obd1 dist and ecu.

 

well, reason why i was asking is because i wanted to keep everything obd0, because i have the complete changeover from the obd0 integra.

 

Well, looks like I will convert the dx wiring back to stock as it was changed a little to accomodate OBD1 vtec. I will then convert that to MPFI.

 

use the harness you have.the vtec wiring will not be used obviously.just remove the obd1 jumper harness and plug in the obd0 integra ecu.make sure you use an injector resistor box.done.

 

This is what you need to do!
Don't do any thing else!

 

removed jumper harness, but the it was modified for the MPFI and such. distributor harness was also modified for obd1 plugs. the jumper harness was spliced and has two sub harnesses that go into the engine bay. i will swap everything back to obd0 and go on from there.
