OBD0 Harness Question
We are trying to put a '91 HF motor/trans/ecu in an '89 Si. We used the engine harness from the HF originally but after it didnt start we realized the harnesses are completely different. I have an uncut JDM ZC harness laying around for some odd reason.
-Are the ZC and SI Harnesses the same? Other than the fact that its RHD obviously
Which harness configuration should we use?
(If you are wondering why we are ruinging an SI, It's because it used to be a drag car with a built boosted b16, and my friend wants to turn it into a dd. The car is rusty as ----, and the b16 is going in his HF CRX. Extra motor plus extra shell= free car)
---- this should probably be in Engine management. Sorry!

Re: OBD0 Harness Question
use the original harness that came with the car.
Fail to do this and you might as well build a harness by hand, it'll be quicker.
Think of the power of three
Three different years of harnesses 88/89/90-91
Three different models HF/SI/DX-STD
Three different countries of manufacter Japan/USA/Canada
Yeah, have fun!

Boy that sounds like my idea of a good time....

Yeah, the last time I was asked about an engine harness for an 88-91 I quoted $220 which is dealer cost. I get them from the dealer for $180. When asked if I could go through their harness and fix it I quoted $350. ---- that ----, it's a stupid waste of time.

Re: OBD0 Harness Question
a buddy and me fixed a hacked up harness, the shop bill for labor alone was $1000 and I'll never do it again!
After trying to trace out what had been screwed up we cut every wire at the ecu and went one wire at a time. Mind you the kid tried the DPFI to MPFI wiring himself, then a local shop before coming to Tim's shop.
Three people had over 25 man hours into the car. When Ryan and me started in on the car if you hit the brakes all injectors would stick open flooding the motor. Took use 8 hours each to get it right.
NEVER EVER AGAIN will I work on someone elses hacked up wiring, I'll burn the car instead!

Really there that cheap for a new harness from honda for an engine harness. My 91 crx hf needs a new one badly.
