Update: the headlights can't be used at all now (even on low beam) without overheating. Attached is a picture of the wiring from above (facing the engine) and pictures of the two relay boxes.

But that's unfortunately the least of my worries....now the truck will crank but won't start. It was starting fine with the new switch, but now it just cranks forever and won't fire up.

From the reading I've done it seems like it's either not getting fuel (clogged fuel filter) or spark (bag plugs). not too sure how to check either of those on an IROC Z28 so if someone has advice lemme know.

This also feels like it could be something else weird since it comes on the heels of replacing the ignition switch ....thoughts?
