i got aSI engine harness and a DX engine harness. im putting a b16 in a 90 DX. which hanress would u use, and what do i have to do to rewire for MPFI?

thanks!

also i forgot this si harness is a place racing harness. is it already rewired or what?!

 

keep the dx harness on the car.

extend the tps wires by about a foot and switch the outter wires.

rewire it using the si injector plugs and resistor pack harness (if you are using obd0 style injectors). then swap over the whichever plug fits the b16 dizzy (you just repin the plugs and match up the colors).

you will need to run 4 wires through the firewall to do a mpfi conversion, and another wire for vtec.


hmm im not sure what the place racing harness is like...

http://www.fourthgenhatch.com/mpfi.html <- explains a lot of things, esp things like repinning and running wires to the ecu for dpfi to mpfi.

EXACTLY

it has a resistorbox on it. get this. it came off of a DX car, and there are no extra plugs over there (on my SI the resistorbox has its own plug coming out of the car)
but the entire harness is an SI harness, and it uses the SI plugs on the dizzy and everything.

bump for info on this harness!

 

Yes, use the stock harness, and mod it. That website (fourth gen) rocks for the wiring. Great pics, easy explanation.

Don't do what my friend did and try to get a new body/dash harness from an Si. The fuel pump plug doesn't match, or the rear lights and stuff. Such a pain.
