    So I decided to change my gauge cluster with "idiot lights" to one with gauges, I followed the instructions that I found on this website, but nothing works on the new cluster, now I'm trying to figure out what my stock wires do or what they're for. Yes I know I should've written them down before starting, but I'm new at this so "rookie mistake" guys sorry, any help would be much appreciated, also how could I test the tachometer to see if it works at all by itself. Thanks.:screwup:

    Never played with the idiot light cluster...

    But to the best of my understanding, the wiring harness is the same regardless of whether you have idiot lights, or gauges. The thing that is different is the flexible printed circuit on the back of the cluster. Take a look at National Parts Depot's online Camaro catalog, page 15, part#C-9744-4A:

    http://npd.dirxion.com/WebProject.asp?BookCode=car09flx#

    That is the correct printed circuit board, and should work if you have a correct U14 gauge package.

    You should not have to cut a single wire.

    To do the swap you do the following;
    old Pin 4 (brown) must be released from the connector and left out
    old Pin 2 (light brown) moves to Pin 4
    old Pin 12 (dark green) moves to Pin 2
    old Pin 3 (dark blue/white) moves to Pin 12
    old Pin 1 (pink) moves to Pin 3
    tach goes into pin 1

    voltmeter has it's own spade plug connection, run lead to the IGN terminal of the fuse box which supplies power only when the
    key is in the on position.

    Thanks Steve, I did the wire swaps and everything that has to have power has it, still no response from the gauges themselves. My printed circuit board looks jacked up, so I just ordered a new one. I hope that will be the end of it (fingers crossed) and my gauges come alive. Again, thanks for the help guys.

    So here's the update, I carefully re-connected my harness and everything worked, except my tach (what a bummer) which obviously means bad tach right? I only paid $60 for the cluster so I can't complain. Once I fix the tach my dash will look awesome. I appreciate all of the help gentlemen!:)
