i ahve an 1986 f 250 and i would like to convert over my old windows to power. has any one done this before and what all is going to be involed in this. i know i will have to run power wires and buy window motors but where or what can i take these items from in the bone yard or at a part store.

 

You can get the wiring harness,motors,regulaters,switches from any 1981-1986 truck or bronco. the motors and main harness are also the same up untill at least 1991. I put window motors out of a 91 in my 80, which had 86 doors on it at the time.And I think the rangers and broncoII have the same motors also.

 

thank you. i am starting to get tired of rollen them down by hand.

 

The motors are the same but a lot of other stuff is different. Go for an 81-6 truck. 80 stuff will also work except for the goofy door locks in the panels.
You will need both door harnesses (grab the power locks while you're at it-you'll be adding the wiring for them anyway), the regulator assemblies with motors, "power" door panels with the switches, the 2 circuit breakers form the fusebox, and the wiring that goes across the dash from door post to door post.
The big harness unplugs at each door post, the back of the fusebox, and has a ground or two. It's easier than you would think to pull it out, just take off the top dash pad and kick panels and worm it out. It will plug right into your existing fusebox and each door harness plugs into it. If you took care pulling it out it will plug right back in, including the little fuse clips in your fusebox.
The 1987 and up harness ties into the main underdash harness. Easier to fabricate it than try to transplant it from a junkyard truck. A major project compared to an 80-6 swap which amounts to just swapping and adding parts.
My plain-jane 82 is sporting power locks and windows from an 86 Bronco. I thought to do the same with my 89 until I discovered the wiring mess. I collected a bunch of the stuff anyway and then sold the truck to my son-in-law who has no interest in power windows so I didn't bother going any further with it. My 87 Bronco already has all the power goodies.
If motors are too hard to find you can use them up to '96 plus many car motors (avoid Lincolns some of them are goofy and not useable). But you may find different plug-ins and maybe only two bolts of the three will match up. Not a big deal, the motors only have two wires, crimp connectors will work. And you can grind out the third hole a bit to get the last bolt in. The motors come in different styles and shapes but generally most "FORD" motors are useable. Beware stuff like Probes which are just rebadged Mazdas and WILL NOT work.
