Topic: So I helped and they hooked up the cables backwards!!!!!!!!!

[94MtnYote]

 Yeah I was giving someone a jump and they got the terminals mixed up.  It was only a few seconds and it made a bad ticking sound. The truck seemed fine until I was heading out to my welding class when the low beams, left corner light and right hand blinkers went out. The bulb on the corner light is burned out, but all the fuses look ok.
Any helpful ideas?    I need to this bs fixed

Woops...  The fuses for the headlights are in the fuse box under the hood.  The relay is in that box too.  Sounds like you may need a blinker module too.  A standard 552 module will work in a 3rd gen so no need to get the spendy stock one.
