I need a wiring diagram for poweRED / heated seats out of a 98 tahoe. Drivers side has 5 wires counting ground and passenger side has 4 counting ground. I want to wire heaters to a swittched only and the power to the battery. Going in a 91 chevy pickup. thanks DCSmothers

Are the switches mounted on the seat? Switches for movement and switches for the heater?

Can you figure out which wires go to the heater switch, and which ones go to the switch for the movement of the seat. If you can locate the wires that go to the switches for movement, if there are only 2 wires that go to that bank of switches, One will be power and the other will be ground. Put a 5 amp fuse in line with your power wire for testing. If you connect it and the fuse is still in tact, go ahead and put a 10 amp fuse in the wire. Try moving the seat with no weight on the seat. If you connect them backwards, the seat will move the wrong direction. So if you move switch forward and the seat goes backwards, you have power connected to the ground wire and ground connected to the power wire. Get those figured out so we can eliminate those wires from the equation.

The fuse is important Please put one. I am sure you will have to up the fuse size when the seat is trying to move with a body in it.
