I recently bought Limited seats from.a Sienna but didn't get the wiring. I'm looking to wire both the front seats up so they function. I have the heater control that by the cigarette lighter. Anyone have any insight as what else I need. I've hooked up the heater controls as the wires are there by the cigarette lighter. The air bag connections appear to work as they connected up with no issues. The seat belt switch connects up as well. I've checked the fuse panel and the fuse is there. The heater seat control lights up. I just need the connection and maybe the relay, just not sure. Any help would be much appreciated. Thanks in advance.
