I have a 91 crx dual point, it's all stock and i'm trying to convert it to run 4 obd-1 injectors, obd-1 distributor, obd-1 ecu, and pop vtec. I can order the jumper harness for obd-0 to 0bd-1 but that only converts the ecu plugs and then it has many wires not plugged to anything. I have an obd-1 harness, injectors, ecu, wiring harness, and dizzy, so i think i have all i really need besides the jumper harness, but now i need the knowledge to wire everything over and make it look clean and be cheap, I really need help, also below is the pic of the harness i'm going to order, lmk if this is the right harness, thanks

 

damn man this sucks, no body has any info., i guess i'm the only retard trying to make a crx fast with a single cam vtec, shit, lol

 

yeah bro i'm trying to get that same info, rywire does it but they charge $300 and you need to send them the dx harness and a z6 harness, that's some B.S. well g/l

 

People have been doing the dpfi to mpfi for the last 15 years man. It's not that difficult to research on google.

HYBRID: 4G DX to ZC wiring conversion

That harness looks pretty ghetto. You can also get the dpfi to mpfi to obd1 through rywire.com if you want to know for sure that it is correct and top notch. They have done more dpfi-mpfi swaps than anyone out there. You can also get a distributor jumper too if you haven't figured out how to swap the distributor plugs.

Stop being cheap and either learn how to do it yourself or keep your car stock. Modifying these old buckets aren't cheap.

 

this is the whole point for this thread, so i can learn hot to do it, i doubt people are tying to be cheap but it makes no sense to pay $300 + shipping + parts for something anybody can do with the right knowledge, anyways thanks but i want to convert the shell to many things as i said, not just dpfi to mpfi, i want fuel injection, obd-1 ecu, obd-1 dizzy, injectors, etc., and vtec that's a few things not just dpfi to mpfi, you say it's not hard to find the right up, but trust me i've been trying for awhile, lmk people thanks

 

Easy. Pre-OBD dpfi to mpfi. Then convert using the pre-OBD0 to OBD1 harness. The cut and solder on the OBD1 injector clips instead of the mpfi pre-OBD clips. Do the same for the distributor plug. 4-wire O2 sensor will be labeled what wires go where on the 0-1 rywire harness.

Or do you want to go the whole OBD1 engine/cabin/chassis harness?

There are many options, but all of them are pretty easy to do. The rywire harness has all the wires labeled correctly so you know where to install the vtec solenoid, pressure switch, knock sensor, 4 wire O2 sensor, check engine light....blah blah.
