let me tell you my situation and what ive done so far: I bought a car (95 Accord with swapped H22a1) from a guy who gave up on the car because he didnt know how to fix the starting problem (he had aftermarket coil that wasnt meant for honda type ignition system, and ICM was fried). Anyways, the harness looms are opened up, some wires are cut, connection was poor, some pins falling out of connectors.

So I decided to order a 5mt H23 engine harness. I was going to add the extra connectors and harnesses. I dont think I need to worry about lengthening any wires because they should be pretty close.

Last night I borrowed the factory service and etm books from a friend and there are 2 connectors beside the VTEC ones, that are missing from the books. I cant find the 2 connectors in the pictures or the schematic or the service manual.

So i just need you guys to tell me yes or no if...

you guys have the 2 big gray connectors (8 pin connector and a 14 pin connector) thats is right next to or below the injector resistor on the Left rear corner below the hood.

I needed to hook up the itake air bypass solenoid (the one that controls the secondary butterfly) just for now because it was missing. I found the pink wire but no luck on the black/yel. etm says the black/yel one leads back to the under dash fuse box. the only way is if i know the black/yel goes through the fire wall and to the connector i am talking about. but the etm doesnt identify it. so thats why i need your help.

 

You can wire blk/yel from IAB to blk/yek wire going to the distributor. generally It needs +12V switched.

you'd better stick with Accord harness and lenghten some wires to match H22 devices.
