Saw this over on denalitrucks.com. Thought I'd give it a shot.
The driver's side already had the mounting holes. I just copied the pattern on the passenger side.
Instead of splicing wires, I pulled the wires out of the connectors and replaced it with the properly terminated wire at the lengths I needed.
I ran the wiring under the insulation for a cleaner look.
