blinker/tailllight wiring issues

[pat]

I’m wiring up my truck right now, and I’m almost done. Before I tore it all apart, I had it wired by a body shop with a Painless kit and everything worked. Now I’m having trouble with headlights/taillights. As far as blinkers, the left side is dimmer than the right on the front and back, and the rear right taillight blinks the brighter filament(correct) and the left side blinks the dimmer filament(wrong?). My reverse lights work, headlights works, but no park lamps in the front, but rear taillights work. Also, is it normal for my turn signals to be slower when the headlights are on? And when my hazards are on, all the lights blink very dimly.
That’s a lotta questions.
But the good news is I can turn the engine over, cant wait to hear it run.
