1990 Ford F-150 • 0.5L V8 2WD •
I have a 1990 f150. Originaly it had a 5.0. Ive taken an engine from a 2000 mercury mountaineer, also a 5.0 and placed it in the f150. I only swapped engines not transmission. Ive taken the entire engine compartment wiring harness from the mercuryand used it under the hood of the f150. I disregarded all wires that werent going to the engine like headlights and crash sesnsors on the bumper and ABS. Ive installed the power distribution box into the f150 also. So all relays are in place. I also brought over the PCM with the new engine. In the new wiring harness there is 3 quick connects with several wires in each one that were leading into the firewall of the mercury to the interior fuse panel and several modules I found as I disconnected the wiring harness from the dash of the mercury. Now im assuming you will have something you can pull up that will tell you exactly which modules are located inside the passenger compartment of the vehical. If not I will track them down. Question#1 I am hoping you can tell me which if any of these modules I will need to bring with the engine? #2 Since I kept the original trans there is a clustur of wires that went to the trans on the mercury not being used. Since these wires arent recieving info from anywhere matter? Will it still run? If I have done anything wrong so far (other than swap engines that are so far apart) please let me know. I would be most appreciative if you could guide me through this.

1990 is OBD1 2000 is OBD2 your best bet is to put all the harness that came originally with the truck, use all the senors from the old motor hook up all that stuff and it shold work fine. OBD2 & OBD1 DO NOT WORK TOGETHER NOR CAN THEY DUE TO THE MUCH MORE ADVANCED ELECTRONICS. It will work fine with all the old stuff in it. IF you did something silly like cutting the harness cause you arne' t going to need it any longer then repair prior to putting it back in.
No the original harness to the truck is still in place. But the old motor had a distributor and the new one has a coil pack. Will I have to put the distributor into the new motor?
