I already did a search, but no one has had this problem that I have seen. Ok heres the situation: Bought a 92 prelude with H22A4 swap in it, got rear ended, totaled car. Bought 94 Del Sol Si to swap H22 into it. Motor ran really good and strong in prelude, pulled motor and looked at wiring and computer. They were using the H23 computer with a VAFC to activate the Vtec, and they had no resistor box connected to the injectors. Now I'm not really sure what to do. I have the D16Z6 harness to use, but not sure what to do now.

Hmm that is wack.

First, what I would recommend, either re-chip the P28 you have, or purchase a P13 ECU. I would recommend re-chipping the p28 so you do not have to wire up EGR, knock sensor, blah blah blah.

For wiring of the H22A4, being that was in a 92 prelude, I am assuming the H22A4 was already converted to OBD1, so your D16Z6 engine harness will clip right in.

Only issues is the distributor. I can't assume anything since the motor was OBD2 and the car is OBD1, they may have either re-pinned the H23 engine harness to OBD2 plug, or re-pinned the distributor to OBD1.

*assuming* they used the H22A4 OBD2 distributor, if they have used the one style plug for the distributor, then they have used the OBD2 male plug on the H23 engine harness.

With that said, you need to modify the D16Z6 engine harness using the OBD2 style plug so you can connect it to the distributor and use it no problem.

If they have converted/re-pinned the H22A4 distributor to OBD1 style, using the factory H23 OBD1 two style plugs, then your D16Z6 harness will clip right in with no modifications.

As for the rest of the wiring, please refer to the first post of the thread I created up top in referance to the rest of the wiring.

From there, everything will be good to go with adapting the D16Z6 engine harness.

I do not have a p28, I only have the p14. The del sol didn't have a motor in it or a computer. I have the motor but it is in pieces. The 18 year old kid I bought it from took out the motor and disassembled it to "build a turbo motor", what ever he thought that meant. What about the injector issue? How do I tell which injectors are on the h22, and what about the resistor box? How did that motor as good as it did in the prelude without it? How can you tell the difference between the obd1 and obd2 dizzy? I can take a poic of it if it would help. The swap is almost done, got the motor in the car, shifter hooked up, a/c and p/s hooked up, now this. Thanks again poison

fast+forward

it probably had obd2 injectors that dont use a resistor box, which is why there is none

So can I run it that way in my del sol?

even though it came out of your prelude, your sure you had a OBD1 motor to begin with right??? Check the dizzy. 1 plug or 2 ??? OBD2 engine harness plug into obd1 car harnesses.

I beleive the motor was originaly OBD2, its an H22A4, but it has a p14 harness on it. Dizzy has 2 plugs coming off of it. Also dizzy has TD-61U 2417 stamped on it, and the part that it bolts to has p13-2 stamped in it.
