For a fullsize print you'll need Arch-B 12x18 paper and a printer that can eat it.
This is Grip Heaters, Horn, Turnsignals, Winches, Load Reduction Relay, 4x4 Override, Backup Lamps, LED headlamps, and Gauges. I'm not using the backup lamps for work lights and I don't have a bypass for the 4x4 override.

I use space saver Micro Automotive relays (.5" x 1" x 1" vs Mini 1" cube) for anything I can. The Micro saves space by using .187" terminals for the low current coil and Normally Closed contact while keeping higher current capacity on the Normally Open contacts by using .250" terminals. Micro Automotive relays are not the Omron ISO 280 relays the how-to warns against. The ISO 280 relays would work too if someone took the time to layout the wiring diagram...
Here's some more on relays if you care...

The diode I used is a GM Delphi Air Conditioning Clutch Snubber diode Part #12135037. They used them on mid 1980's G body cars. It's the same form factor as an ATM fuse so you can put it in any inline ATM (micro) fuse holder. Your GM dealer will have them or you can get em from Mouser Electronics.
Higher output 921 bulbs may help light output... rather than the 912 bulbs called for. I don't use them except in reverse so I'm unsure what would happen if I used them as work lamps.
