STS radio/ignition problem

[im2gq4u]

My 99 STS has decided that when the key is on accessory power, the radio, windows and speedo screen will light up and work, but when the key is turned on and the car starts, everything goes dead. I have been told it is some sort of harness of some kind and I need to know the location of that harness. I have my radio out currently so I can go ahead and work from there. Thanks

I'd say Ignition switch is no-good. If it was in the harness you would NOT have anything at any time.

Replace the ignition switch before you go digging in that harness. Tis' be a pain in the butt!
