    i just tapped into one of the wires that plugged into the back of the factory gage cluster. just traced the power source that one of the dash lights used, and tapped into that.

    I am not sure about the newer trucks wiring colors , but the Blazers I have worked on had a gray wire for the dimmer switch , off the headlight switch , off the stereo harness , and off the cluster harness .

    For my tach I cheated , I took the dash lps fuse out , stuck my wire against the blade and pushed it back in . Hasn't pulled out , and the tach dims with the dimmer switch :thumb:

    Thanks guys And Pauly My diagram looked like the grey wire but it was a little tough to sort out. I looked at the cram and jam method but I didnt want to crack all of that circuit board looking stuff back there Thanks all

    I seem to recall that one or two of the accessory terminals on the fuse panel is also run with the headlight switch, but I confess I didn't look at the wiring diagrams (linnked previous) to double check.

    fusebox tap..

    The "old style" trucks from 73-87 had a tap in the fuse box with a male spade sticking out marked "PNL LHTS" or "INS LMPS that works with the dimmer on the headlight switch,just like the dash cluster lights...I assume a 91 with the "old" style body should have it also..beats splicing into existing wires..:crazy:
