Well I bought the triple gauge A pillar from Dan Thurs. It looks great and now I bought 3 52mm gauges from ebay. They are called Prosport performance gauges.I got a boost gauge, fuel pressure gauge, and a air fuel ratio gauge. My problem is the wires are to short to reach the engine bay to splice them into other wires. I see these wires are silver colored inside and I put some copper wires to extend then but I don't see any holes that go from the drvers side to the engine. I put the wires through the side of the car but now I need to know where to splice the wires. I know where the 12V is cause I connected my boost solenoid to it. Now I need a constant energy source, a ground wire? I guess and a hole to put these wires through and if possible a wire that turns on in the dark cause in my SLE in the day the cluster is white and in the night is red and these gauges I bought have this function. Any help will be appreciated thanks!!!

I'm confused a little with your but you can connect your ground wire to any metal part of the car.

i Always just use the constant and 12v source from the radio and the boost guage can be tapped into a vaccum line

3 posts in and I'm more confused than before I read this thread. Can somebody translate for me please?

Look at where your steering column goes threw. There'* like a foam cover there. You can poke threw that and pull the wires threw. It will close up again after the wires are threw. I use a phillips screwdriver. Tape the wire on, poke it threw, remove wire and tape, pull screwdriver back out.

Oh sorry let me clear things up. I bought gauges but the wires dont reach the engine bay. I want to know where connect these wires to power up the gauges. Im going to need to extend the wires out into the engine bay cause theyre too short. There are 5 wires theres a red,green,white,black, and orange. The instructions say red to a 12 volt source, black is ground (thanks nighthawk) white to a constant source, green to the "o2 out" wire so the air fuil can read the voltage of the airfuel, and orange to a headlamp to change the colors in the gauge from white to red. I know in my SLE the light in the instrument panel turns from white to red in dark places. I want to splice the orange wire to what ever does that so i can have the gauge white in the day and red in dark places. any help would be greatly appreciated.
