I installed a Scheel-Mann driver seat with heaters and I'm looking for a switched power source to use with the provided seat wiring harness. The harness contains a relay that sits under the seat where the harness connects to the seat heaters and only has a red and black wire for power. There is also a connector in the harness for the seat heater switch, which has high, low and off. I dug into the dash to see what power source might be available in my 85' FJ60. I found the unused connector pictured below which sits between the rear window defogger switch and the cigarette lighter. Looking at the FSM diagrams it looks like this might be for rear fog lights used in the Euro models. One of the four terminals in this connector has 12V switched power, but I'm not sure which circuit this is connected to in the fuse panel and thus what the amp limit is. The Scheel-Mann harness contains a 10amp fuse on the red wire so I assume I need no more than 10amps of current. So will this unused connector in the dash work to power this one heated seat and if so can anyone tell me which connector type and terminals I would need to plug in to it?
If this connector is not a good source for powering a heated seat and I want the seat heater on switched power can I add a second relay to this seat wiring harness? This second relay would be wired to constant 12V power from the battery, and triggered by a switched power source to then provide the power to the seat harness. I watched the Cruiser Cult video on tapping in to the stock electric harness the clean way, but the connector in the drivers side kick panel is plugged in to a Koito Relay Cleaner Cont (see pic). I think this is a relay for the headlight washers. Can I tap one of the wires going into this headlight cleaner relay for the switched power source for the heated seat relay, or is there a better option?
