I installed a d16z6 a few months back with the help of H-T ... thanks once again but i have been using my stock CX harness and stock ECU. I manage to get a hold of a manual p28 and finally a harness this weekend. Found harness at a junkyard for 50 buck. the problem is it was off of an automatic so the are extra connectors on the harnes but the needed o2sensor is there and vtec solenoid is there. my question is can i use the automatic harness. i have a 92 civic so i was hoping i could just install this harness and change to the p28 and it's instant vtec. let me know if i can do that or if i will need more wiring near the ecu to get it all working... well i will stop rambling now but i just luv the honda stuff ... LOL.
PS- I did the swap all by myself in one day ....

 

For what i know the 92 is the only year that you are able to plug a vtec harness in at the strut mounts and not have to add from there to the ecu. the auto i believe has wires in the empty spots on the manual cars. you should be able to plug and play without wiring. your car like i said before being a 92 has the vtec wiring in the car harness already and it is the only year that honda did that in the civics so no ecu wiring is needed to run the P28 in there.
