VetteVet, is the man when it comes to electrical.

Just some general things to look at first.
Battery of truck grounded to frame are motor.
Motor grounded to frame.
Cab grounded to motor
Cab grounded to frame both sides
frame to bed both sides.

All light housing's are grounded to the metal of the truck some how. Clean all spots good.
Dash cluster should have a ground wire running to the dash also seperate from the harness.

Old thread and the OP hasn't been on since 5/16/20. Don't know why it never went any farther. It ended kind of abruptly.....

Sorry for not coming back, but I did figure it out, the hard way.

Apparently I wired all my turn signals wrong. The wireing instructions were not very clear from LMS. They claimed that if you had this one year, you use this wire and not that wire and so forth.

I eventually just made some jumper wires for the weather packs then trial and errored it till they worked. I can't remember the specific wire colors that I ended up with at the moment though.
