I am currently in the process of doing a swap. I have the OBD0 to OBD1 conversion harness. Now my question is: "Do I use my original HF engine harness?" Will the plugs work on a VTEC head? Any help with this is appreciated. Thanks!

 

Yes everything will plug in for the most part, there might be a plug or 2 that won't plug in but this is normal. o2 will not have a place to be plugged in as obd0 uses a 1 wire and obd1 uses a 4 wire.

The conversion harness will have wires for you to run to the VTEC solenoid, Pressure Switch, 4 wire o2, etc.

 

Is there a post or sticky of the HF engine harness diagram on this forum? I tried searching and no luck. I want to know what each plug or connector is for. Thanks for the reply dephtone!

 

try looking in the FAQ 2.0 thread on the main page...!!!
