Swapping manual to power seats
hey i was wondering if anyone could help me?
I have a 2007.5 new body style chevy 2500hd silverado LT truck it has manual seats in it but i got some heated power seats out of a 2008 chevy silverado LTZ to put in my truck. the passenger seat pluged right in and the driver seat wont. My truck has 4 wire for the driver seat and the new seats has 14 wires and i was wondering if anyone could tell me how to hook it up. i have looked all over the internet and youtube and i can't find anything on how to hook it up or a wiring diagram on it. Thanks Adam |

This is the factory plug in the 2007.5 chevy LT. i cut the red and black wires and connected them to the red and black wires on the 2008 LTZ pigtail to see if i could get it to move in any direction. it wouldnt move at all.

Re: Swapping manual to power seats
4 wire plug has hot and ground and 2 small wires for the seatbelt buzzer
14 wire plug has the same 4 wires, the rest are for seat heat and memory functions unfortunately the memory functions require a new body module to operate hook the red/white to red/white and black to black to make the seat work tie the seatbelt buzzer wires together at the plug :D as for the heated seat... your on your own |
Re: Swapping manual to power seats
Thanks for your reply.
I hood the red/white to the red/white and the black to the black and it wouldn't do anything. Someone told me that I would have to hook up more than just them two wires. But he didn't know what color wires all had to be hot (+) or (-) |
Re: Swapping manual to power seats
Does the drivers seat have memory in it. Most people have no luck getting the memory seat to work..:chevy:
|
Re: Swapping manual to power seats
Yes but I'm not wanting to hook it up. All I'm wanting to do is to get it to move. I'm also trying to find a switch for the dash so the heat will work to but that will be later. I'm just wanting it to move up, down, back and froward

Re: Swapping manual to power seats
post a pic of the under seat wiring
there may be a relay box that you need to bypass should just be 2 wires into the switch |
Re: Swapping manual to power seats
Drivers side Lg red ,lite blue and orange to 12v power black to ground. Passenger side lg red to 12v power black to ground

Re: Swapping manual to power seats
Ok I will try that. I can't get the pics of the seat to upload but I will keep trying until I get them to.

Re: Swapping manual to power seats
All of them pics are of the drivers seat. The passenger seat just plugged right in and worked without cutting any wires.
If u need more pics let me know and I will try to get some better ones Thanks |
Re: Swapping manual to power seats
Hey I went and got a car battery and brought the seat and the battery in the house and hooked the red, orange and lite blue wires together and hooked them up to the positive (+) and the black wire to the negative (-) on the battery and it did not work
Do you have any more suggestions? Thanks |
Re: Swapping manual to power seats
I was perusing a factory diagram for the seat circuit and the actual relay controls inside the module are wires labelled A through H. But, the relays inside appear to be of a solid state design requiring a 5V reference signal to actually move. I'll do a little more research into it for ya....

Re: Swapping manual to power seats
Just went and checked my seat and sorry mistake it was red/dk blue and orange. Lt blue is for heater controls.

Re: Swapping manual to power seats
your going to have to do some work
regardless of how many wires and sensors you have for the memory, the seat still has 3 motors and a switch all the other stuff is just stuff. stuff that needs to be cut out and thrown away the easy way would be to look at the passenger seat and hook everything up similar to the pass seat the switch should have 8 wires coming out; hot, ground and 6 wires, 3 pairs for each motor each motor has 2 wires that need to be hooked to the switch not sure if the drivers seat switch is rated for motor loads like the pass seat switch is you could just set the pass seat in a good spot and transfer the wiring harness and switch over to the drivers side :D |
Re: Swapping manual to power seats
Ok that's a good ideal! I will try that when I get back in town. Thanks for all y'all's help!!
|
Re: Swapping manual to power seats
I tried it with the bark blue wire to and it still didn't work
|
Re: Swapping manual to power seats
I put 01 Cadiliac 8 way power seats in my 68 and that's the ones I had to use and the plug on your seats looks very similar I will try and get some pics of the wiring
|
Re: Swapping manual to power seats
Ok thanks but hey it was worth a try! I don't have the seat in my truck yet I'm just using a car batterie. That should work right? I don't think the seat should have to be grounded anywhere since I'm hooking the black wire to the neg. (-). Do you know if that's right ?

Re: Swapping manual to power seats
I had 2003 Tahoe electric memory seats that I got from my local yard and could not get the drivers seat to work. Today I Brought them back and got 2002 trailblazer electric seats without memory and they work perfect..

Re: Swapping manual to power seats
Ok. Do you think I have a bad seat? I looked and the passenger seat has only two wires and they are red with a white line and black wire

Re: Swapping manual to power seats
My passenger seat had 6 or 8 wires and it worked fine, but the drivers had about 200 wires. I was told by 2 good chevy mechanics that the only way to get them to work was to rewire the whole assembly and bypass all the computer stuff. so it was a lot easier for me to bring them back and look for a non memory set
|
Re: Swapping manual to power seats
I just took the lrg red hook to 12v + and lrg black to 12v- then started adding wires to the + side till the seat moved then started removing other wires till it stopped moving and those are the ones you need for your seat. I used a jump box for testing. All functions work and they are memory seats that I have.

Re: Swapping manual to power seats
probably not a bad seat, it's just going to take some work to get it operational
if that is above your skill set then try to take it back realistically you have 3 motors with 2 wires each figure out how to hook up 2 wires to a motor to test it |
Re: Swapping manual to power seats
I guess I had a bad seat! They let me bring it back and they had a lot more seats come in and we found one that would plug right into my truck and worked fine.
I would like to thank everyone for y'all's help!!! Adam |

Re: Swapping manual to power seats
I realize that the OP has his issue worked out, but I thought I would post my rendition of wiring the same type seat.
I used 99 Cadillac seats that also had the memory position sensors. I eliminated the memory wiring part and wired them with new switches. I used one rocker switch for each motor, with the switch reversing the polarity of the motors. It actually worked well, and I was able to fit the switches where the openings of the old switches went.
