I recently bought a 1990 RX-7 and the one problem I have with it is that the taillights do not light up when I turn on the headlights. Now I've searched around the forum to find a solution but I found out it might be the light switch and/or light switch harness. I'm not car savvy but before I buy the parts I'd like to hear other peoples opinions first. If anyone can give their advice i would be much appreciated.

 

Look at the back of the light switch and see.

Pretty much confirms the problem if you see it.
