h23a swap into '99 prelude - Honda Prelude Forum

im sure this has been posted and explained before, im just having research issues i guess.

1) Anyone who has done the h23a swap into a 5th gen, if you used the engine harness from the prelude, did you have any clips left over; like not plugged in?

I cant seem to find where the remaining clips would plug into...
maybe the h23a doesnt need those plugged in since its obd1...

I have the obd1 ecu, ecu jumper, distributer, and distributer adapter waiting. I just wanted to make sure i have everything hooked up before i go further.

which ecu? what kind of software/tuning agent? which plugs do you have left over? can you post pics of them?

ECU- chipped obd1 from rywire.com
Software- chrome

here are some picts:
- the 1st: is a top view, those sensors are underneath the intake and or intake manifold...atop of tranny
- the 2nd: underneath car,left side... closest to pulleys
- the 3rd: underneath car, right side... closest to tranny side

it also might be hard to see. but in the 3rd photo there's a wire that seems to look like some kind of ground. Ideas on where/ what I should do with that?

The one in pic two im certain is the crank position sensor, that you wull not be needing since you have the CPS in the dizzy, hence the dizzy wire adapter.

also is this car and sh?

Everything you need to know, easiest way for some of the sensors is to use your old distributor and oil pump or buy new ones for you car from the dealer, don't hack your wiring.
