i bought an 2003 gmc envoy. this truck has become my baby,and its basically all i got.im not very well off according to a poor man's mentality.but im pretty swift when it comes to learning,following directions,and so forth.i catch on fast.but to make a long story longer,when i finally got under my hood it was a mess.wires EVERYWHERE. even got headlights wired up with speaker wires.i bought a year worth of alldata to try to help me remedy this problem,but that was just another problem because i never learnt how to read wiring diagrams. could anybody walk me thru re-wiring my headlights and other lights? when i try to use a blinker,my hazrds come on. pretty messy situation.thanks in advance
