[QUOTE="josephcostello, post: 16695168, member: 165586"] So I wanted to share exactly how I am going to wire this car with the hopes that maybe somebody could benefit from it...it took me almost a whole day researching this to figure this out and thanks to two threads over 10 years ago it finally made sense for me. Every single harness on the 03 04 cobra is different. This does not mean, however, that you necessarily need them. On this car I am going to use the 04 PCM harness, PCM, dash harness, cluster, PATS and engine harness. The body harness is only different from my understanding because of the dual green wires for the double pumps. On my coupe, theres a ground that's in a different location than the 04 convertible harness but I believe that's just a difference between coupe and convertible. This is where things get interesting. Plug C210 is the grey connector that connects from the PCM harness into the body harness. This plug is the same on both cars. The wiring is not. On my 01, there was one green and yellow wire that mated and originated from the CCRM. This goes directly to the Inertia Fuel Shutoff switch (IFS), and from the IFS a pink/black wire goes to the FPDM. From the FPDM, a slightly thicker grey and pink wire goes to the pump. On the 03 in the same location on C210, there was one white wire. This originated from a DIFFERENT location on the 03 CCRM, and ran to the IFS, and then to the FPDM. On the 03 right next to the C210 connector there are the two magic wires with a connector for either side. Those two green wires are in the body harness and run directly to the FPDM. This is to allow the higher amp/volt draw from the dual pumps. The solution to modifying the body harness is to first connect C210 into the body harness. Cut the white wire from the PCM side and ground this. Then cut one of the green/yellow wires coming from the CCRM (doesn't matter which one, they end up splicing together 3 inches from the CCRM) and put it into the white's spot. You're done. Or, you can do what I'm gonna do - ditch the single green and yellow wire in the factory 01 harness and replace it with the 19' double wire as the 03/04s were designed. Again, from C210 to IFS, then to the FPDM, then finally my dual pumps. Notice how there is still going to be a single wire from the IFS to the FPDM, this is what the wire upgrade that comes with a BAP is for.
