Rewiring my EFI Magnum - 1970 Dart Swinger
Hey guys, I'm going to post some of what I've been up to with my 70 Dart. This thread will be about the rewiring engine and transmission harness of my EFI Magnum equipped 1970 Swinger.
This mini build thread follows a thread where some members helped me figure out how I should rewire the engine: Do I really need the wire from the alternator to the bulkhead connector?
First, a bit on my car. It's a 70 Swinger with a 1994 5.9 Magnum, Doug's headers, Hughes SER0814ALN-14 cam, Mopar M1 Magnum EFI intake, Mopar Performance OBD1 PCM, and 53 mm throttle body. I'm running a 46rh transmission with a 2500 stall torque converter, and a 3.23 gear in an 8 3/4 rear (for now). I pulled the engine out of a retired ambulance turned hunting / camping rig, and put it in my car with the only upgrade being the cam, and the headers which where already in the car from my old LA 318. All the other upgrades came later. The car works amazingly well, and I'm super happy with it.

I'm doing this because:
- The van harness required extensive modification to work in my car. The PCM was on the driver side firewall of the van, but I wanted to mount it to the passenger inner fender, so lots of wires were lengthened and shortened.
- I didn't wire it with an ASD relay, which is the relay that powers the coil and fuel injectors. I just wired it to the coil positive with the ignition start and run connected together. It worked, but I couldn't get the need for a relay out of my head.
- I want to try to get the factory cruise control set up.
- I want to put the headlights on relays.
