I got a 90 Si hatch.. and puttin in b16a3 ... i got the ecu wiring part done.. Now the question is.. do i have to do any wiring to the engine? I have both the Si harness still and the 94 delsol DoHC harness .. what do i do?

 

you're putting in an A3?? why? are you trying to use the hydro tranny too?

 

a3? cuz i got it for free.. i got a cable tranny..

 

lol...oh, okay..i was just wondering why anybody would pay like a grand more for one instead of just getting an a1.

 

True......

 

what ECu are you going to run? Use the Si harness. Let me know

 

Im running a P30 ecu. everythin that came off of the 94 delsol vtec... i got a pigtail harness for the ecu already..so the wiring to my ecu is ok.. i juss want to know about the wires in the engine bay.. if there is any changes needed from my SI

 

No. The harness should have had everything for you to hook up that you will need. I dont know what kinda of harness this is...but all my harnesses require the stock harness and the modifications are in the adaptor.

OK koo.. thanks Blown90 Hatch

 

I have a B16a2 in my 91 CRX w/ cable tranny. I just used a PW0 ecu, so it plugged right up. As far as the engine bay, i used the stock si harness and added the few extra wires. This setup works ok, but i also had to utilize a Vafc to raise the vtec crossover. Trust me, 4.4k crossover sucks ***-cheese on a second gen B16a. Its also hurting for a higher fuel cutoff. 8k on the pw0 just isnt cutting it. I think a chipped PW0 or PR3 is the cheapest way to go.
