Changing wiring

I had to drive 300 miles to get the merc seat. I only needed one little piece off the frame and a couple motors. It was an all or nothing deal, seat, 4 window motors & regulators plus two front doors. What I am saying is those parts are very rare and if you find them the cost is premium. Unless you are doing a restoration a front seat with manual levers would probably be a better choice. If anyone needs a pair of '54 Merc hdtp doors (same as the Ford except for trim holes) I'm the guy to see.
 
Update on front seat. It's not hydraulic. There was what looked like a clear 1/2" tube that I thought was for fluid . I cut it so I could get the s at out figuring it was going to be replaced. It was a wire within the clear tube, so it's electric, yay. Pulled up the carpet, pretty much in one piece. The padding under it, or if that was soundproof, was also intact. The floor is still 95%paint with a little surface rust, no hole in the floor pan. Amazing. Next is the headliner,
 
The wiring of a door window motor. Your regulators will be different, this one is from the rear window for a hdtp, but the wiring itself will be the same. The relays can be opened up for cleaning the contacts fairly easy. As you can see it is a bit more complicated than modern electric windows.

Just a general wiring comment....
When you are cutting leads to a connector or motor or steering column, etc. be sure to leave at least 4" of wire so you have enough to attach or solder to new wires. And if you buy a part from a junkyard make sure the guy who goes to get it leaves 4" of wire on the part. If he clips it too close, the part can be worthless.
 
I use a lot of different connectors depending on what results I want with a connection. I use two types of bare spice crimp sleeves if I want to attach to an existing lead that is still serviceable and then I cover the whole splice with shrink wrap sleeve. I keep about every size of shrink wrap and the more common ones I also have several different colors. A person can't have too many resources when working with electrical.

I still do a lot of soldering when necessary but avoid it if I can. I always pre-tin the wires before soldering. It just works better that way and keeps the solder joint clean & ready to stick. Solder with small diameter rosin core if you want good results.
