Help! Autometer Hook Up!
Help! Autometer Hook Up! Ok I have a 5" tach. I need to know where you guys hooked up the power and where you hooked up the ground. I have a LT1, which wire to I tap in for the RPM's.
I need to know a 12v power source that isn't on 24/7, just something that comes on with the ignition or light switch!
NEED RECOMMENDATIONS QUICKLY THANKS

ANY PICTURES OR WRITE UPS WOULD BE GREAT! MAYBE EVEN A SCAN OF THE DIRECTIONS TO HOOK UP! I bought it used!

The white wire coming off the coil going to the PCM and from the PCM to the dash cluster is the wire to tap into to get a signal for the Tach.
as far as the power for it your fuse box has two or three empty spots use the one marked ASSY, or IGN those will only turn on when the key is on, and for the ground use any bolt or screw going into metal. good luck

Ok sooooooo...........Some guy who had an LT1 told me it's the white wire under the passenger kick panel.........here is what happened.
so I tried to tap the RPM wire, which you said was white, but I did it and it didn't work, then I realized as I was connecting it off and on, my interior lights were going off and on. hahaha. so I was like hey i'll try to white one with the black strip. (WRONG) Then my security light came on and wouldn't let me start my car, I locked the doors, alarm set, then I opened the doors, teh alarm went off (usually i turn it off by putting the key it and putting it on the ON position, but that didnt work. It went for about 3 mintues and shut off, then it let me start it again (PHEW)
So i have determined it's not the white or white with the black stripe. Any other suggestions...I scared now to just tap wires now.

its not loose under your dash, if you are going to tap in under your dash you are going to have to cut the insulation off your main harness going to the dash cluster, its much easier to tap in right after your PCM, then there is no confusion
