I'll start this off by requesting mod's to move this if it isn't properly posted. And thank you a head of time for any valuable comments.

Please help me ID these seats, and possibly point me towards any power seat electrical diagrams or the like. I picked these up off Kijiji, to install them in my '85 F-150 frame-off resto. I do not need heated (if these are equipped), or memory recall, only interested in up/down, front/back, tilt, and lumbar if equipped. You'll see what I have for electrical, all motors are complete I am assuming, as well as an ecu mounted under each seat.

I know they are from a '97. Unsure of model...

They have headrests, full power, and I have the rears as well - however not interested in installing the rear seats.









Electrical under the driver's seat with grounds:






Electrical under the passenger's seat - looks like the grounds were cut off with everything else unlike the driver's?






Can someone clarify the switch operation?
Looks like front/back/up/down, tilt (what does the up arrow and up/down action here represent??), then lumbar switches?, and then memory block.






Here is my project progress I am starting body work, which was why I picked up my seats in case I needed to modify the cab floor if I couldn't make the seat brackets fit nicely.

 

full size range rover P38.

 

Also, the seats connect to several other modules not present. The RAVE shop manual has about 12 pages of electrical diagrams for those seats, including the colors for various motors, position potentiometers, etc. May require quite a bit of modification to make percolate at a basic level. Here is one page from the manual.

 

Thank you for the help. Once this RAVE manual completes I should have an ok start.

These other modules they connect to, is that something that would normally be mounted underneath that I am missing, or elsewhere like under the dash?

 

Couple of locations, which are shown in the RAVE. But you won't be able to make a body control module work without an ECU, etc. IMHO the way to proceed is identify seat motor wires and try using 12 volts on the bench to move them. After all, once this truck is complete only a few will be driving it. Earlier ROvers had no such module, just switches.

My F250, 130,000 miles on barrier islands, did not look like your frame. There is just something about salt water mud in hidden places.

 

I can't believe it's been five years but I thought I'd come back and update. I'm finally ready to play with the body stage of my 1985 F-150 resto so I decided to tackle these seats last weekend before I figure out the mounting for them.

Thank you for the help! I was able to get it with full function from the switches aside from the memory recall, including the power head rest!

The original harness I pictured in my first post actually wasn't used at all. The forward/backward & up/down switch as well as the backrest/head rest switch are double pole double throw, and that's what saved me. Each switch is sent a common hot lead in, common ground out. The DPDT switching allows the switch to control the output to the motors without the need of the potentiometers and servos as originally equipped. The lumbar pump is given a hot lead, and is fed back to the switch as needed and completed by a switch ground out. I didn't alter anything behind the switches.

The connections are only butted and taped together so I can put it on the floor of the cab with a 12V battery and check fitment and comfort. If I like it, it will come out and be fully soldered and wrapped neatly.

As you can see, I removed most of what I could and that is from one seat. I still want to decide if I'll use the heated seat function as the truck will only be used in the summer. I'll remove the memory switches and fill them in when I colour match the plastics. The seats will get reupholstered once I figure out my interior theme.

So it can be done, and thank you!
