the gentlemen with the fury in the pic wasnt going to do that. we made our own harness. we just posted pics to this thread because he was doing something similar to the 5.2 in the E body. this car (gold fury) used factory dakota wiring harness modified and the 5.2. he is trying to do this as simple as possible. justin

Fired the car up for the first time tonight! Plugged in most of the harness, and tapped 12V off of the alternator and 12v ignition on source off of the old coil wire, temporarily. If you take out the ballast resistor and jumper the terminals you get full 12V on start and run position in the ignition switch. Still did not plumb a fuel system, just running it off of a pressurized tank for the moment. Now for permanent wiring since I know it works. Thanks to Justin (wldtm) for all of his help on this car
excellent! I'd sure like to know what wires are necessary for making the engine and computer function so I can retain my stock dash etc if I go that way. Nice job!

The best thing to do is build a wiring harness using a 94-95 dakota schematic. You will need an ASD and fuel pump relay socket. This is the part where you will need to do a little modifying.
It depends on how much stuff you want to keep. You could keep AC, overdrive trans, and cruise if you wanted to...
Use the vehicles stock sending unit to run gauges ex) temp, oil psi, volts
I can make this harness for interested parties

Found an oversight in my parts selection this afternoon. 5.2 and 5.9 magnums use the same oil pan, not like 318 vs 360 LA. When I first filled it with oil I had a leak and chalked it up to me screwing up the gasket install. After the second one this afternoon leaked I looked it up online and got conflicting stories. MP tech line confirmed that I need a 360 car pan instead of the 318 pan for the 5.2 or 5.9, and they said the one piece rubber gasket should work. Minor issue, but annoying!
the one piece does not work. I know. unless you adjust the pan, it will leave a gap at the front and back of the motor. you need to use the LA gasket set.
