'93 Toy p/u.
Left turn signal and brake light have both stopped working, yet the constant-on driving light and backups lights do. Bulbs are good.
The brakes and driving lights are 1 bulb w/ 2 filaments, 3 wires.
I have this vague feeling I read somewhere that these trucks' turn signals switch the ground, not "hot". Is it the same case for the brakes?
Since it's both at once, I'm assuming it's something farther in...?
