On the 91 W250s did they put the wiring harness in the floor for power seats even if the truck was a base model? I want to change out the bench seat out for the power buckets, but I need to know if some wiring is needed.

 

I didn't think power seats were an option on 1st Gen trucks.

 

in 93 you could get them, but i don't know about 91.

 

My 91 LE did NOT have wiring for power seats. When I installed a set of power seats from a 94, I had to run power from an auxillary fuse block.

I didn't have the wiring at all. I added to mine to put the power seats in. I'm taking them out. I don't like it.

 

No wiring in my LE either. There just wasn't that much luxury in the world in '91 I guess.

 

Not an answer to your question, but I thought I would mention it.

My 92 has the split bench from a 94 installed (the kind with the fold-down console). I haven't spent any time with the stock seat, but the previous owner assured me the 94 seat is way more comfy than stock.

Two pieces of "z" channel appear to be the only custom parts required, and the seat is slightly offset to the right, and it is a little tight on the right side against the door.

 

Caryl and Rob,


How did you run the wiring for your seats? I'm really thinking about doing this with mine. Any sites with diagrams or any thing of that nature?

 

Just giving ya a hard time! I've been called a lot worse!!

I have installed an auxillary fust panel on the left fender of my truck. From there, I just ran a 12 ga + & - wire through the firewall. There is a big soft rubber plug that I use forf this. Just punch a hole and run the wires through. From there, I ran them, in split loom, down the floor pan over against the left side. There is already a trough there that has wiring in it for the rear speakers and the done & cargo lights. From there, just came up throught he carpet at the right spot. All the seats need is 12 V + & -. Real easy hook up.

My '93 FSM does not say anything about power seats. I don't think they were available.

 

Boojie!
I basically did the same thing. I ran a fused supply from the battery and fed it throught the firewall grommet. I would suggest using a coated two wire purchased from any auto supply store.
Any power seats I've seen only need the supply and ground connected to them. The seats are usually self contained with all the wiring, switches etc.

 

Thanks for all the help guys. I have a service manual on the way for this truck, so that should help with the install.
