This should be an accurate representation of the circuit. Now for the fun part trying to meld the three circuits on to one board. The last two schematics on the page I will put together on one board and add a few things concerning the oil pressure warning and alternator circuit.

Once again, thanks for the help. I would like to learn how to use LTSpice and it would be awesome if they had a tutorial circuit that were included. Currently there is a mental disconnect that I will have to work on somehow to get over the learning curve.
