I recently traded a ford focus for a 1989 5.0 lx convert. I thought i got the better part of the deal because both cars needed work. The problem is when I put in the battery one fuse gets super hot and also a group of wires that go to the ecu. The previous owner had replace the wiring loom and there is a ton of wires that don't match up ! i have a wiring diagram but its like greek to me. Any advice??

If you can't read wiring diagrams, you need to either learn how or find a friend who can.
Find the problem wire or circuit using the diagrams below.
