5.2 5.9 magnum EFI plug and play harnesses

The one in my 66 Fury is the only "mounted" one I have pictures of, but the batch I have for sale differ in mounting.

The ones I am selling now mount the computer behind the passengers side of the motor. THe harness is long enough that you could feeed it through the firewall and put it behind the dash if you so chose. There is a small power distribution box that then mounts in the drivers front corner of the engine compartment. It houses the 3 fuses and 3 relays you need in a small, neat, self contained unit. You could hide this under the battery tray if you so chose. The wires that mate to your car come out at the rear of the drivers side head, right where they'd need to tap into your bulkhead. Simple and easy....

From your donor van, youd need the entire motor assembly, sensors and all. All the sensors are bolted to the engine (coil, injectors, throttle body, intake temp, coolant temp, dist, CPS) and you can remove it as one unit. Youd just need your motor assembly and the matching computer.

You do not have to send me your harness, I am selling them outright....no core needed.

To use the 518 from the 94 van, just bolt it into your vehicle. This harness connects to the neutral safety switch just as your 904/727 did. You can use your speedo housing/cable from your old trans. To get OD to work, you can use either method mentioned above. Some people want it on a manually flipped toggle switch, others choose to get the $85 pressure switch from PATC that makes all 4 gears fully automatic, even lockup (if your van has it.....2 wire plug is non-lockup, 3 wire is lockup). You'd need a driveshaft 3 inches shorter than your old 727 trans, but the yoke is the same. Obviously, you know the 518 requires a bit of floor surgery to fit....

for a fuel system, go to any parts store and order a fuel pump for a 1991 lincoln mark 7 LSC. Its the same pressure and flow rating as the magnum, but is small enough to put inside the tank. pull your sending unit out of your tank, cut off the pre-filter, and mount this fuel pump onto the intake tube. Make a small bracket to keep it firmly attached. Drill a small hole at the highest point in your tank, put a grommet in it (tightly), and feed the two pump wires out through it. put the sending unit back in (with a new seal!). One wire from the harness goes to the pumps positive wire, the pumps other wire goes to ground.

Magnums used both returnless and return fuel rails/regulators depending on year. You will want the one WITH the pressure regulator on the rear of the drivers side fuel rail, as this will return excess pressure to the tank via a return line. Seems the dakotas had these systems. If it doesnt have the regulator on the rail, then the vehicle originally had the regulator in the tank with the pump. You can still use this style, but you must buy a (pricey) external regulator. Just nab a dakota rail and be done.

anything else?
