I hid the wires for my headlights today and hopefully will be able to start filling holes/smoothing out the engine bay this weekend.
Before (first picture is some relay/fuse box thing):
The box was screwed into the engine bay originally but I welded it onto the inside of the fenderwell so there were no screws poking into the engine bay:
I lengthened the wires going into the car by 3 feet so that they would reach. I also had to add 1 1/2 feet to the wires going to passenger side headlight so that i could run them behind the shelby front apron
