Like Mark said, you could make it a pretty simple deal. You will need to decide which caliper you want to use as your wear indicator and bring the wire from the inside of the truck to it. I have found that the firewall plug on the passenger side has a couple of unused contacts in the bulkhead connector, and you could probably bring the wire through one of them for a nice clean look. You could use either the Tandem Lock or the Overspeed light ports in the cluster for your illumination. I think I have a spare harness that I could chop off a bulb pigtail for you if you need one. I just recently did something similar and used the Overspeed light as my lockup indicator for my 700r4. I'm using a manual lockup switch, and although I can listen to the engine and determine if I'm locked or not, I decided that I wanted to get fancy and mess with a buddy of mine who thinks that the idea is overkill.
