Hey all,
I have been having significant problems with my swap as I just made the thread pertaining to the transmission. Anyways the h22 is running like **** and I have a solid cel. I was told that the harness could be faulty. This is an h22 in a 91 accord. Could the main harness cause misfiring and a solid cel?

so when you check the codes with the jumper wire you get a solid cell?

 

a solid cell usually means there is something wrong with the ECU itself or the connection to it. make sure everything is connecting right and soldered not buttconnected. The harness could be bad or it could be just a loose wire.

is the harness obd2 to obd1?

 

I checked the ecu, there were only two connections altered, but its an obd1, its in a 91 accord....

you need to convert from obd0 to obd1 probably.

 

A 91 is obd1 I think... Anyways, there are three altered connections from the ecu, the knock sensor, vtec pressure switch, and vtec solenoid...

your accord is obd0. the ecu is obd1....you need to get an obd0 to obd1 conversion harness and your problem will go away.

I intend to just change the entire harness over to OBD1
