Your best bet is to modify your existing harness. It isnt hard. Cut solder heat shrink. Done deal.

Trying to use the other harness is going to be a huge pain.

i would have no problem with that if i new how to rewire it

You could also just give $120 (I think) to Monotech and he'll send you a a plug and play harness for a DPFI to MPFI in a 88-91 CRX/Civic DX. Little labels on all the plugs and everything. Though, it really isn't that hard to do it yourself. It's only swaping a few wires and adding for four injectors.

IMO, Monotech all the way. I had a hard time with the DPFI-MPFI swap wiring. It CAN be done, but then you also have to worry about buying the injector pigtails and cutting 2 pins with like 3" of wire left for the ECU pins. Plug and play all the way!!.

im try to rewire will a 0bd1 injetor box work ??

Are you running OBD0 or OBD1 injectors?.

 

[9894411]

obd0

 

[89' Project Civic]

I believe you can only use the OBD0 injectors with an OBD1 resistor box.

 

[D16SiHatch]

say what!? there is no such thing as an obd1 resistor box. that's like an oxymoron. the boxes are for obd0 pre 92 peak and hold type injectors.

OP: if you are using obd0 injectors then you will use a resistor box, and if you intend on using saturated obd1 injectors, you will not use the resistor box. simple as that.

I honestly figured that but I got told to shut up about shit that I don't know what I'm talking about, so I didn't say anything because I honestly didn't know.
