I have a mutt of a setup. I have a D15b2 90' crx hf motor, I have a stock wiring harness from a 91' civic std, and to bring the two together I bought a injector harness will all the plugs and resistor box from a 89 teg. From what I can see the dizzy plugs are different. Basically I need to know how to bring it all together. Please help me.

 

First off, do you have a D15B2 (DX DPFI motor) or a D15B6 (HF MPFI motor)? What trim is the car that you are dropping the motor into? DX, Si ?

 

yeah is your car dpfi or mpfi, because hte std hareness is a dpfi, but the crx hf comes mpfi

 

I am dropping a mpfi hf motor into a std hatch with dpfi.

 

Your easiest option is to convert your existing DPFI harness to MPFI. You will need an injector resistor, and the injector clips off any OBD0 MPFI harness. If you can, you should get the distributor plug as well off the MPFI harness. Don't try to swap out the entire harness, just add the necessary wires that you will need. IM civickiller, I'm sure he can help you out with the wiring.

 

Yeah, 89 teg harness will have everythign you need but the distributor plug.

you can steel that plug for n an 86-89 legend (o firewall, not on distro) or some other car.
