So today i called up my friend who is a electronic genuis and showed him the schematic for the TC lock up switch that guzzle made. He laughed at me because I was clueless to what it was and went out and bought all the parts. He wired up the box for me and such. Got it all together and it worked like a charm. Thank you guzzle for the excelent write up on how to make the lock up and not having the od light flash! I love it! It fun to let it lug in 2nd gear and watch the coal run out the stacks.
