Obd1 engine in obd2 car
I did an obd2 to obd1 swap and i got some probs.
I got a conversion harness and a p28.
I was using the obd2 ecu before but obviouly i was getting codes, but engine worked pretty well never the less.
Now, when i connected the harness and p28 the engine didnt wanna rev over 5000.
I only got code for 02 heater sensor .. but that wont make the car act that way for sure.
I `think` it might be the dizzy connection wires. The car harness had been previously touched so there is some confusion between the harness and dizzy.
However when i plug the obd2 ecu back .. it works great again.
Can anyone tell me what dizzy wires go where ??Ie: obd2a engine wires to obd1 dizzy ?
Help pleASEE
Tks

Re: Obd1 engine in obd2 car (civic_ekek)
1.This is what it looks like. The one piece connector on the left is the OBD2 from my d16 dizzy. The two connectors on the right are from my OBD1 harness I got with the motor.
2.This is a pic of the OBD2 connector I cut from my d16 dizzy. This connector plugs into your wiring harness.Cut your dizzy with as much room on the wires as possible.
3.These are the two connectors I cut from the OBD1 wiring harness I got with the engine. They will plug up to your new OBD1 dizzy you now have to go buy.
4. These are the connections. I crimped them, but soldering them would be better. The colors match up perfectly. Mine were a liitle faded so it threw me off a little, but you realize which ones they hook up to. ie...white to white.....Goto hondaswap and look at the "clicking noise" post I started and you wrote in. I posted the color chart there just in case.

Re: Obd1 engine in obd2 car (ekb16)
Thanks ! That pic and wire colours from hondaswap helped me big time.
One other question, are the wires same colours on the ecu sockets side ?
Askin this because mine are slightly different.
I`m trying to understand exactly where do these wires end up on the ecu side.
Anyknow know ?? Or maybe give me the wire description like: CKF etc ?

Re: (ekb16)
no prob thanks for the info man.
I`ll take apart the harness and see whats goin on in there in terms of wires, sliced and sliced
... thanks
PS: However what do you think could cause the engien to rev only till 5000. When i stick the obd2 ecu it works fine. Could it be the dizzy connection s then ? ..I donno what to think. No one has givin me an answer on this one
