i swapped a H22A in for a H23 in a '92 and the harness i recieved with the H22 is all cut up, can i just plug in the v-tec ecu into the non v-tec harness or what should i do? please help.

this link will tell all.

Good Luck

 

You can use your old h23 harness.

You'll just have to wire vtec to your new ecu.

You can use the thread above to do that

 

i have read the site you guys posted and it has helped a lot, but the only thing i am stuck on is the "p13" ecu...the ecu i recieved with the h22a has 4 connectors in it, and the diagrams i see on here only show 3....but there is a tag on the v-tec ecu and it has some #'s on it with a p13 in the middle so i take it that is what it is.....so what is the 4th connector? it has 4 wires in it off the harness: green/red stripe ; green/white stripe; green/yellow stripe; blue....help me please.

 

Can you show us a pic of what you are talking about?

 

i just recently picked up an H22 swap and my P13 ecu only had 3 connectors. Can you post pics of what you are saying?

 

here are some pics:

i hope someone can help me out...this is the only thing i have no idea on.

 

looks like an auto p13 to me.

 

it is an auto car, so are the spare wires in that clip vtec?

 

my stock obd2b wire harness was really chopped up and jumped by the previous owner's ricer wiring, is it easy to find a new/slightly used obd2b wire harness? how much are they ussually?

You have to be careful there are JDM P13's that are manual that have 4 plugs. the fourth connector is for the traction control feature that was found on some models. So just because it has 4 plugs doesn't not mean that its and auto ecu, but you are correct on this one that it is for an auto.

As far as the fourth connector, I believe that is for the traction control feature for the JDM cars and has nothing to do with v-tec. I could be wrong but I have never seen a USDM auto ECU to compare it with.

 

the reason i suggested it was an auto ecu is the fact that the sticker ID's it as an atuo ecu, thus the AT on it.

 

so if it is traction control, would it hurt anything if i just left it unhooked?
