Wiring issues. Need help!!
 

Hey guys I just got a 96 long bed single cab and the dash lights don't turn on. My friend said it's just the switch but I want to make sure first. Also the tail lights are not working when I turn my running lights/headlights on. The brake lights and the reverse lights work just no running tail lights. Anybody know what I should check first? Also they are aftermarket tail lights.thanks guys!!

Start by esuring that all you fuses are in fact good .. pull them and run a resistance test or a continuity test on them ..
