Hi Kitty,


He can jump 12v direct to the pumps and forget the main fuel relay and messing with the ECU

>Sort of a similar thing thatg some do to use the rear red fog light position as >an esxtra brake light, yet preserves the fog light function? I forget now. Sorry.

I just replaced a busted tail light in my wagon, and thought who needs fog lights?

Maybe modify the foglight switch to be active with the ignition on (instead of the low beams on) and use the fogs as DRL without all the low beam baggage.
For the rear, Unplug the upper fog wire and run a wire from top to bottom
brake lights and have twin brake lights.
This works with the low current Red LED's. Way more light and way less current.
Yes you use red LED to shine through a red lens. Yellow LED through a yellow lens, etc.

Has anyone been able to salvage sections from Volvo taillights that look like
they are cemented together with PVC cement ? Maybe there's a trick to getting them apart? Heat gun?

Easy does it with that eggnog, especially the high octane variety!

Bill
