Silverado Radio Power Problems

    I recently installed a Alpine IDA-X001 into my Silverado but I have one problem. I noticed that there is 2 orange power cables coming from my vehicle. 1 I hooked up as the main power lead and the other to the switched igniton lead. I can not get the Alpine unit to turn on. I tested the 2 orange cables for voltage with the igniton on and I am getting 12 volts from one but 0 from the other. I tested both power leads today and found that the ignition switch wire is not giving off any voltage at all. Even when the ignition is on and the car is running. Is there a fuse for this wire any where?

    - Check the radio fuse it never hurts
    - Gm usualy uses one orange for the dimmer control, try playing around with your switchand see if the voltage is raising/lowering
    - if your vehicle is 2003+ you have to be using the gmlan01 harness that basically tees off to the aftermarket deck, and you still have to plug the stock deck in (or the module version), if you are, the ign/acc wire runs to the relay, its usually red, and it doesnt work, run a piece of wire from the ign fuse in your fuse box (visible when you open your driver door) and use this wire as the ign/acc wire.
    - usually ign/acc wires are red, make sure you got the right wire.
    - usually they put the 12v, ign, and ground, sorta beside eachother, 2 powers ontop, and ground on the bottom.

    if none of these seem to check out let me know what year and other info like ex. are you using a wirirng harness or did you just cut the stock connector off?

    I cut the stock connector off. I checked and I don't have a red wire coming out all I have is 2 orange wires besides the speaker wires.

    I checked the 2 orange lines for power. 1 is definitely constant 12v the other one has no charge at all. I tried dimming the lights and raising them but the voltage was still 0. The only other power wire is black and that is ground. How do I fix this?

    Im not gonna tell you you cant cut the harness buddy, i mean obviously you did, but on all gms03+ you should used the relocater harness or the even more expensive t harness module. your stock radio controls, chimes, apparently, abs and airbags and a buch of other small things like the signal noise (tic toc noise), i would highly reccomend using one of the two harnesses, either way, if your not going to gm is usually
