93 3.0 to 93 4.0 swap

[93Ranger4x4]

Ahh, ok, i understand now looking on your build thread, i'll have to pop out the under the dash white plug in and check those wires with the other harness, then double check that the wires are correct on the under the engine harness.

I'll repeat what AllanD said. You NEED to swap the entire engine compartment harness out. There is an ignition module for the EDIS on a 4.0 Truck that should be on the driver's side core support. On a 3.0 truck ( i have one now) there isn't such a thing..... as 94 and below 3.0 Rangers use a distributor. ALL 4.0 Rangers use EDIS.

I've been entertaining the idea of a 4.0 swap again. The first victim would have been my 2.3 4x4. But it ran out of life and I had to pick up another truck. I now have 3.0 4x4. The 3.0 is a nice upgrade in power, and would be a nice engine in a car......but not in my truck. It sucks on mileage the way i want to drive it. I need a low reving engine......like a 4.0. Too bad my 4.0 parts have seemed to disappeared.......

Now to get back onto subject.......

Just swap the main engine compartment harness out from one truck to another. There is a black plug over on the passenger side that you'll unplug( don't worry about the stuff that controls the HVAC stuff), then unhook it all around. Going from the light(headlights, and turn signals) plugs, to that ignition module I was taliking about, making your way to the driver's side fender, where you'll undo the fuse block, PCM plug, and that white cannon plug on the driver's side firewall. Don't forget the horn plug....It's way down beloow towards the core support. Lift both of them out of both trucks and swap. Then when you drop the 4.0 in plug the "on-engine" harness into the donor harness. Simple as that...... and your 4.0 will run when finshed.....

You have no need to swap out the interior wiring.....that's what the cannon plug is for. The pins should be in the right place.

sounds stupid, but how exactly do you remove the cannon plug from the drivers side? i've tried pushing the tabs in but I can't get to them all and push or pull at the same time. also if the donor is a 4.0L and an automatic, all you should need is the computer from a 4.0L and a m50d rig right? all the wiring is the same in the engine bay? can I swap in a gauge cluster from a 4.0l-m50d rig and have all working tach/gauges as well? I have a 89 ranger and the donor rig is a 92 eddie explorer.

I plan to rebuild the 4.0, run a computer from a 92 or a 93 (not sure which year, its was at the scrappers) that had a 4.0l and a m50d, and run a gauge cluster from a mazda navajo that also had a 4.0l and a m50d. just want to know if it will all work, sorry to thread jack!

I cant remember the exact size, but there is a bolt in the middle of the cannon plug, just find the right size socket you need and start loosening the bolt, the bolt doesnt come all the way out, but you should know when its enough to unplug it.
