I have a set of seats out of a 99 obs tahoe both power and heated. Im putting them in my black truck and id like to make the heated park work but the wiring is not working out for me. I can hook a jumper box up and make the power part of the seat work it just seems I cant get the heat to work.

Driver seat plug has 2 big orange wires, a ********* wire and a small brown wire
Passenger seat plug has 2 big orange wires, a ********* wire, small brown wire and a small yellow wire

I know the orange wires are hot and blacks are grounds, does anybody know what the brown and yellow wires are? if I hook either to ground or power the heated part still doesn't seem to come on.

Silly question, but does it have an on/off switch?

-Just saw your reply, You're welcome. I came across that a few weeks ago, and had it bookmarked.

The switch is off/low/hi but it doesn't light up or anything so idk if its actually coming on ,I couldn't seem to get them to come on when I was playing with them and I want to make sure they work before I have the seats redone. Figure now would be the time to fix them if they don't work.

Looks like brown is a 12+ for the on/off and temperature switch and yellow is a signal for the temp that goes from the sensor in the seat to the module(probably can't see that connection) and then also to the seatbelt(the wire you're talking about).

So for testing you need to have the orange and brown connected to your +. The black goes to -. When yellow is grounded, it won't heat, it should heat when it's not connected to anything. You might have to get the belt buckle to set it up to work like factory -I'm not sure if your current buckle has the connection it needs.

When installing, orange goes to an always hot in the relay/fuse center under the hood(not sure where exactly, need to find a power distribution diagram or look at an example vehicle) and brown gets connected to a key switched +(again, power distribution diagram would be helpful to get it 100% right per the factory).

Did you ever get these to work? I just bought the same seats for my 98 suburban not realizing that the trucks didn't all come with the same harness. I found the heated seats actually have their own circuits in the factory fuse box under the hood but the pins aren't in it because mine didn't originally come with them.
