After I installed my cd player in my 87 RX7 the taillights and the gauge cluster lights don't work. Does the cd player have anything to do with the problem?

 

hehe.... last time this happend to me.. it was becuz my Light switch went bad...
then again... who knows. yours might be Ezer to deal with....
but check your wiring and see if there anyburning or melting on the back of the switch... if there is. well... Icemark duz rebuilds

 

you probably used the parking light wire (red/black) in your stereo installation and if you are lucky, blew the fuse. If you ae unlucky you burned out the light switch.

Disconnect the mazda factory red/black from the stereo you put in, of if you just left the wire bare, it needs to be covered.

And yes I do have headlight switches on my website if you burned yours out.
