My radio is controlling my headlamps! help

[Luke Perry]

Hi, a couple days ago I posted regarding a problem I thought I was
having with my fog lamps. This is on a 91' Coupe. I diagnosed the
problem incorrectly, it seems that in the headlight "off" position,
whenever I turn the power on to my radio (non-factory) it turns on the
headlamps.

I recently had the radio installed by proffesionals (or at least I
assumed!) so I wonder if they crossed wires somehow? The radio works
fine. Do the wires that provide power to the radio on a 780 also used
for the headlamps? I just want to know before I bring it back to them
to try and fix.


thanks
lp

Well, generally there's a wire from the lights that takes power to the
radio to light up the radio face when the lights are on. If they wired
this wire to something on the radio that is for the power antenna for
example, then turning the radio on would turn the lights on as well.
