Default 90 JDM B16A engine loom

My friend just got his B16A from Hondamotorsonline.com and it is hella clean. The entire engine loom is there and I was just wondering if it would plug in to the existing interior wiring harness plugs on his 88 CRX DX. The plugs look as though they would plug together but i didn't know if the pins inside each plug are set up the same. Originally i was going to just modify the stock DX harness to work with the B16 but now that i see the B16's harness i just wanted to use it. If there is problems with the pins then i'll just modify the DX but B16 harness is so clean. I know that either way i'll have to drop lines into the interior loom for the KS, VTEC press, VTEC solenoid, sec. O2, CYPs and i think that's about it. Thanks in advance!

Don't forget that you are going to have to change a lot of the wiring to convert from dpfi to mpfi. His car currently runs a primary injector and a secondary injector setup while the b16 runs four fuel injectors. The b16 harness should plug up but I am pretty sure things are going to be pinned differently due to the car be rhd. I just modified my stock dx harness to run mpfi and then ran the four extra wires required for Vtec, KS, and the secondary O2.

i've checked the haines manual for ECU wiring and my JDM cars ecu wiring is completely different to USDM wiring, so i would use the jdm loom/wiring to keep things right.

Yea thanks for the advice. I went through and pulled both harnesses apart and found out that they are really different. I used the DX harness as the base then added in what i need to from the B16's loom. Just finished the wiring yesterday and i think everything should be fine. Latez
