Boost Guage Question???
I was reading the directions for once!!!! and it says to hook my power wire up to something that doesn't loose power while cranking or it won't function correctly. I was thinking the radio, but im pretty sure I recall it lossing power while cranking. So my question is where is a good place to hook it up at. And also there is another wire that says 12v allumination where do I need to hook that wire up at? I know this is alittle stupid question but bare with me im no electrician.. Also it is a 2000 Trans Am
Thanks for your help,
Jimmy

A test light will verify that it doesn't shut off at crank. Its important that it stays powered up, otherwise it will recalibrate while the engine is pulling vacuum making your boost read artificially high.

The 12v illumination lead needs to go to your parking light switch. That's used to light up the gauges when the lights are on. You can hook it up to the same lead as the power lead if you want the gauge lights on all the time (which is what we do in our race cars).

I used a tester to find a source that kept power under cranking.

Later, I went back and split the wire, installed heat shrink tubing, soldered it together, and shrunk the heat shrink tubing around it.

I wanna say it's the orange wire under the dash where the steering column is. Can't remember though since all my stuff is wired to a seperate fuse block in the back of the car. I'd get a voltage tester and try that one first, just don't mess with the little yellow wires. Damn airbags.
