When I did it, The fuse panel (top right in the picture) is powered by a 2Ga cable (which also powers my stereo) :D
Hey Ryan I see you have a one touch window module installed for your rear window in this picture. Can you tell me anything about it? I have been toying with the idea of installing them for my windows. I also like the way that you have wired the window and will be copying the idea for mine since I currently have nothing in the way of wiring since my harness came from an F-150.

First look at the original wiring here:
http://fullsizebronco.com/forum/showthread.php?s=&threadid=9397


NOTES
This wires the switches so they both work without the key in the ingition.
It also takes the load off the dash switch. Now the dash switch only suplys 1/8 amp for a relay
For this to work well you need a GOOD ground near the relays.
You need to route a 10gauge or larger wire to the relays in the back.
I mounted my new relays in the back inner quarter panel above the wheel arch.
I recomend replacing the power wire for the tailgate switch; wire it to the same circuit as the relays.

Ray McCormick...will this cause the dash switch to work?

Thanks
Ok you're responsible for getting a Battery HOT wire threw the firewall. I'm anal about wires and fuses so any help from me will be very complicated for this simple electrical work. It needs to be BIG.

INTRUCTIONS
From that Battery HOT run a 18 gauge wire to the Lite Blue / Black wire on the dash switch. This will make the switch work without the key.

Also cut the Pink/Green and Pink/Blue wires. Splice 18 gauge wires to the switch and route them to the drivers kick panel.

Run a 10 Gauge or larger wire from Battery HOT to the drivers kick panel with the 2 18Ga wires from the switch.

Remove the Door sill cover and route all 3 wires along the drivers rocker panel past the seat belt tensoner trim panel and up to the drivers inner quarter panel above the wheel arch.

Drill a hole threw the inner quater panel and route 3 10ga wires down to below the drivers tail light. I prefer a Red wire Blue Wire and Green Wire. But if you get all Purple wire, I don't care, just keep them from getting mixed up!

Behind the Drivers tail light are the tailgate plugs. I recomend removing any questionable wiring, but your wiring skill may stop that from hapening.
Splice the Red 10Ga wire to the Black/White wire
Splice the Blue 10Ga wire to the Pink/Blue wire
Splice the Green 10Ga wire to the Pink/Green wire

Now at the inner quarter panel mount 2 relays. try to sand down the metal at one of the screw holes as you will use that for a new ground. This Ground has to be GOOD!

Wire up the relays as the diagram above shows. When you splice all the power wires togeather make sure it's not a half ass job. Same for the grounds. The better your power and ground the faster the window will move and the less it will bind up under load.
Does the 2----18 gauge wires run to the back with the 1----10 gauge wire?

My dash switch doesn't work...will this fix it?

Thanks

nobody's commented in this thread in over 2 years. the thread starter went MIA long before that and the other recent guy was banned.

you'll have better luck starting a new thread in the Noobie Tech section (no post limits there) so you can get the direct help you want.

The original diagram disappeared with the OP. Steve83 has several upgrade wiring diagrams on his Supermotors. The one labeled "Improved `87-96" works with both switches hot at all times like the modification in this thread. It also adds relays so the main load doesn't run thru the stock switches. There are several other options shown in case you want a different combo.
