First off i have tried looking around for answers and im still a little fuzzy on things cause everyone's talking about p06 to p28. I have a 92 cx hatchback with a d15b7. the previous owner had a d16z6 swapped into it and when he blew the motor he swapped in the d15b7 but left the p28 ecu and wiring harness. i know that the d15b7 runs fine with the p28 i would just like to go back to the p06 so it will no longer have a cel for vtec solenoid. My question is will the wiring harness have to be swapped too or can i just plug up the p06 and roll on. Thanks In advance guys.

 

there may be a few extra wires (VTEC) but everything you need for the P06 will be the same for the P28 harness.

BTW-if you're interested in a one for one ECU trade, PM me.

 

Thanks man that's exactly what i needed to know. I figured that but wanted to make sure. and i already have a p06 ecu so no need for me to trade thanks though.
