I got this hatch shell with a obd2a harness in it so I converted everything to obd1(injectors,distributer, alternator) and noticed I don't have a iacv plug... Anyone know what pin it is in obd2 to run your own wires?

tony_2018

Please google obd2a ecu pinout.

I tried and it started missing and **** so I reconnected whatever I cut. A12 and 14 right? 14 is iacv and 12 is just iacv. Unless what I read was wrong

Did you convert the Ecu?What engine?

Boostedbeaver

P28 ecu on jumper with d16z6

tony_2018

tell me what wire did you put into both of those pinouts? Only one wire should be hooked up to the ecu and thats a12 the other one leads to somewhere else.

I don't have an orange wire in a14 in my clip I got the black and blue in a12I thought it was the red/yellow at first but it's not

tony_2018

So where is the other wire connected to?

Boostedbeaver

It isn't period I looked around I can't find the blue/black wire or orange one anywhere near the motor but I know the blue/black is running off the ecu

tony_2018

You just said the black/blue wire was in a12, so where is the other wire connected to?

Boostedbeaver

Yeah there is one in a12 but there is no orange wire period dot lol

tony_2018

Why do you keep bringing up the orange wire, I didn't ask about the orange wire. I'm asking about the two wires that are in my diagram PERIOD DOT OP FAILURE

Boostedbeaver

Alright my bad i misunderstood you. There is no iacv plug in my bay

You don't have a 3 wire tan plug like above at all?

Boostedbeaver

No plug at all no cut wires on the harness nothing.

Do you still have the OBD2a engine harness?

Maybe the IACV plug is incorrectly plugged into something else. The original OBD2a IACV connector has 3 wires. Remove the intake system and post pictures of the sensor connectors on the throttle body.

HondaPartsHero

Why not just tap into your obd1 adapter harness using a round tow wire connector?

#1 will tap A9, #2 will tap A25

He still needs the iacv plug though
