Heres what i wanna do. I want to make my car plug and play with a MPFI harness. I have been looking around and got a ecu pinout sheet for the si pm6 ecu and the dpfi pm9 ecu. PM6 88-91 OBD0 Pinout i made - ClubCivic.com - Honda Civic Forum PM9 http://psytronix.org/engine/pinout.html I know im still going to have to add 2 wires from the ecu to the shock tower. The plan is to depin and repin my body plugs and add the 2 wires into the body harness and shock tower plug so i can plug in and run a obd0 ls ecu or a pm6 si ecu without any modification and have it work. I have the body harness im using out so its nice and easy to inspect/ work on. now i basically want to turn it into a si body harness. has anyone here ever done this? does anyone have any input besides telling me to find or buy a si harness.. or the ZOMG DONT DO IT! Id really appreciate any help and info. i would love to make a nice writeup on this with good photos. P.S; I just woke up and havent had any coffee so im like off right now.. ill check back later and see what you guys have to offer on the idea.
