I bought an 86 F-250 6.9 that supposedly ran great. Well, turns out it needs a lot of work but the original alternator was shot and while looking for a replacement, I found some info about swapping a 90s 3G alternator on the truck. So I went out picked up a 130 amp unit from a 91 Mercury Sable with the 3.8L. After looking up and printing out wiring diagrams for both my truck and the car and thinking I had it wired correctly, I have no power to the truck at all. I wasn't able to get the harness from the sable or one from a crown vic like the info I found said. Can someone give me some good detailed info about this so I can get my truck running? Thanks.
