My car = 1991 crx dx (d15b2 5spd)

I have parts and pieces of a half assed MPFI swap, an OBD-1 ecu jumper for an SI. Need a dizzy, inj box and ecu.

I also have a complete (wrecked..oops, but running) eg coupe.

I was wondering if anyone has ever swapped the WHOLE chassis harness/fuse blocks from a eg into an EF? It'd be a true, complete OBD-1 conversion.

My car is gutted at the moment so I was thinking of just changing everything over. Figure it'd be alot cheaper and cleaner than finding unknown condition pieces to finish it off and still be left with other crap to do. The chassis harness and fuse block is UNCUT/not hacked and pulled from the EG. Not to mention the harness is much cleaner. The things I know I'll had to change are light plugs, but that should be easy considering I can just look at the wiring on them and cut the connectors off and change them over to keep the stock CRX lights working.

Does any of this make sense, at all? I've been gettting stuff for an MPFI swap but nothing seems to be what it is supposed to so now I'm left with a bunch of **** that won't work together, etc. So I figured this would be the easier way out lol, plus I can sell said misc. parts seperately for $$ to fund my y8 head swap.

You'll need to rewire your VSS depending on what cluster or VSS you decide to use. How about the climate control? fuel pump, rear lighing? seat belts?

 

Yes, plenty of people have done this. My CRX currently has a full Integra OBD1 harness. I'm getting ready to pull it all out so I can go OBD2A instead.

 

I'm currently doing it for OBD2a as well. But why not just fix the MPFI harness since he already has the jumper harness..

 

why the **** would you switch to obd2

 

beside the better cel

 

Better CEL? It's mainly for smog legality in the state of California. Doing a swap and having it BAR'ed, you need the emissions from the Year/make/model of the vehicle you got it from.

 

On my 97 civic I read the CEL the same way I do on my obd1 crx. Use a jumper and count the flashes. There is no "better cel" only a diagnostic port to plug in a code reader, that in all honesty you don't need. Those codes u read on the scanner are generic.

 

what dohc4life is saying that obd2 is pain to mod. more sensors more cel's more hassle.

 

I will be using the eg vss. So it plugs in. The 95 cluster for now for ease of swap.
I don't have climate control, radio, etc. The belts are being swapped from door to pillar mounted belts. Rear lighting should be easy enough, only a few wires, same with fuel pump. I will cut off the eg pump side and solder it to correct ef wires.
Thanks for all the answers.. This is a completely gutted street car.
It's got no dash, no a/c, heat, blower motor, radio, speakers, sound deadening.
Just an insturment cluster ziptied (lol) to the steering column support until my aluminum dash is done and the gauges are all finished up.

 

The jumper harness is for an Si, mine is a dx, so it wouldn't plug in would it?
I'm not sure, that's the reason I'm asking. If I could just switch the 4 wires on the chassis side, then the wiring would be correct for the jumper, I would do that and just add the injectors (OBD-1 style, no resistor box) and plugs and be done, but I wasn't sure if the DX harness on the Si obd-1 jumper would be an issue. Don't want one hot wire to be where a ground is on the ECU or something and then I fry all kinds of **** because of 1 wire being different on a dx than an Si. lol.
