I have Stock OBD1 Injectors for a 95 d16z6, so there is no resistor box right. I am also using and injector wiring harness I cut of from the obd1 harness and extended it to the ecu. I am using also using blownhatchs obd0-obd1 conversion harness. My injector wiring is as follows I got it from the Haynes book (brown injector 1 A1, red injector 2 A3, l blue injector 3 A5, yellow injector 4 A2). Is this wiring correct I read on some boards that Haynes books are crap. I would also like to know since I am not using a resistor box what do I do with the yellow/black wires on the injector harness. I read somewere on this forum that you just wire them together but there was no final answer and that is what I have now all wired together. But my buddy who helped me with swap said that it seems that might not be distributing the fuel properly and tha is why it is boging and it takes a while to rev when you it the trottle and yes I switched the wires around.
you have to match your driver (ecu) with your injectors.
if you are running 0bd0 ecu, use low ohms injectors.
it is ok to go the other way around ( obd1 ecu with low resistance injectors as long as you have a resistor box for the injectors.
the car will run, with obd0 ecu and obd1 high resistance injectors but only untill you burn the ecu or injector.

It is all obd1 that is ecu p28, dizzy and injectors. And I did match up the injectors to the way the haynes book says.
I wish i could help you (probably i would). how did you wire those injecctors directly to the ECU. Cuz my injectors are not spraying. Also im not getting spark. My swap going terrible 2nd gen b16a into 88 crx hf. Could you help me littel bit how did you wire everything. I know that the yellow black wires go to the 8 grey plug on obd1 harness. Also in that 8 grey plug only 7 yellow/black wires connect to each other with that metal plate. 4 wires yellow/black from injectors 1 from oxygen sensor and 1 from some other sensor i forgat wich one was it and the last wire goes inside the car on obd1 car. So i guess that yellow/black wire it is something i think is ground im not sure .
this might help but i dont know.
when i was doing the obd1 conversion i tried to "gang wire" the yellow and black wire to the red and black wires and use obd1 injectors. when the car wouldnt start i pulled each injector to see which werent firing. only one injector was squirting fuel. i switched back to obd0 injectors and a resistor box and havent had any problems with them anymore.

Well I have blownhatch obd0-obd1 conversion harness and I cut the injector wires from the conversion harness and matched each one to the one its sepose to go to. I used the Haynes manual from the 92-95 year to check out the p28 ecu wiring diagram. An yes one goes to the O2 sensor, EACV, and Purge Control Solenoid which I dont know were it is? And the last one goes to relay called pgfi. I am really thinking of using obd0 injectors but can I use my obd1 dizyy?

What dizzy are you using d16z6. If so did you repin it to obd0? How did you do it? Because this obd1 injector wiring stuff just seems to complicated and I really need this car since it is my only ride. I think I can wire all this obd1 wiring but it will take a while. Doing all this made me realise on why I see so many people with pm6 and a vtec controller on their cars running d16z6 on obd0 injectors.
