Excursion heated seat wiring?
I've got an Amazon replacement seat heater for my 2000 Excursion. It has a black and red wire. The stock Ford seat heater plug has 2 yellow wires and 2 black and red wires. Is yellow positive and black/red striped wire negative?
Thanks all

LOL. I think I was answering you on Facebook.
Without diagrams or testing, my best GUESS is that black is ground and yellow is positive... And that there's two of them because the backrest and butt part of the seats are separate units.
I'll check the diagrams when I get to work.

I had 4 wires on the old plug, and 2 wires on the new plug. I wired up the old plug but only use 2 wires. And the heat seat is not working. Do you think I need to hook up the other 2 wires to make it a closed circuit ? Then it might work?

For some reason, I thought the Excursion seats were on a timer type of situation, from the control box under the seat instead of a relay like the SD, and the SD seats had the stat. I know the EX heaters are in series, so if the butt heater is bad, the lumbar wont work either. When I removed the heater from the bottom of my EX seat, no thermostat.
I have SD seats in my EX now and the heater will stay on indefinitely. Also, the diver butt heater is bad. I tested with my old EX seat heater, just plugged it in and then both worked. Still need to change it.

I'm sure they can, I added heated seats from scratch to my 2001, and was able to use the intended fuse locations, etc.

You'll need to round up all the factory controls, under seat harnesses, and the electrical shop manual in order to get everything correct and understand the various feeds.
You will also need the correct seat side trims allowing the heat switch to be installed, and the heat switch. The 2002 probably works the same as the 99-01 in that the push button function is on it's own small amp circuit, and it triggers the heat module under each seat sending voltage to the heaters which are on their own separate larger amped circuit. I think I also remember seeing the heat module being incorporated into the power memory seat module when I've rifled through the junkyards. I currently don't have schematics beyond 2001.
