Gauge lights flashing

[chargermick]

I just installed a new under dash harness from Year One. The fuse for the dash lights blows as soon as I hit the headlight switch. With the fuse blown, the lights in my aftermarket gauges flash constantly even with the headlight switch off. The right directional indicator and the left front directional also flash with the gauge lights. Could this be a bad ground somewhere? I tried troubleshooting with the wiring diagrams in the service manual, but I'm getting nowhere fast. Can anybody point me in the right direction? Thanks.

the orange wires are the dash light circuit , one of them is grounding blowing the fuse ,& or you have the dash lights plugged into the guage feed curcuit as it is regulated with a pulsing 5v feed , first disconnect the lights from the guage feed circuit , usually black wire & connect to the orange circuit & see if the short is solved , if not search out the short to ground

Thanks Chryco, I traced out each wire one at a time. Finally found the pin in one of the dash lights was grounding to the housing. Once again, YOU ARE THE MAN!!!
