    Unhappy No radio or lamp lights after boost gauge install.

    OK, so starting from the beginning. I bought an SPT boost gauge, had the wiring harness connected an working but that gauge never worked right(got it replaced, broke the replacement trying to fix it, yea Im a dumb a$$). Anyways, bought a defi red racer boost gauge instead. Took the SPT harness out and connected the Defu harness to the clock with wire taps.

    Defi gauge / clock harness
    red(power) - blue & red stripe
    black(ground) - black & yellow stripe
    white(illum) - yellow & blue strip
    orange(ign) - yellow & red strip

    Originally had the white and orange reversed and that's when the problem started. Now my radio, dome lights, ignition light(red ring) will not turn on and my clock will the passenger seat belt light, but not the temp and trip gas milage. The doors will also not lock with the remote or drivers door lock all(turning the lock twice). I can only lock the drivers door with the key and the button on the door panel.

    Im now going to just connect the gauge with fuse taps, but the (expletive) has already it the fan and I'm feakin out over here.

    I have checked all the fuses under the dash and most of them in the engine bay(except the fuel pump, fan, hi/low replay, etc...). Just took the dash apart again and double checked the wires. The only difference from when it was working was the SPT wiring harness, maybe I'll try and put that back. Use the illumination somewhere else.

    There is no need to start another thread. Get a multimeter and the factory service manual wiring diagram and start checking. Undo what you did first and go from there. You probably lost a ground.
