If you are just using your system for race or quick shots for towing, then a few simple on off light will do. Personally I need to see if everything is working when it should be. Lets also not forget how cool an array of LED's look! I used a total of 8 LED's of various colors to indicate what is happening.

I removed the original CD player from the dash which made a great place for my control panel. I fabricated the panel out of a piece of sheet aluminum and painted it black. It is held in with allen bolts. I don't think this could have worked out any better.

It's not pretty but it works. This is all of the resistors for the led's soldered on a separate board. Unless you can make a custom pcb board, you will be stuck using the Radio Shack pre-made boards. Getting everything that you want on one board in a nice layout is difficult. It usually ends up being large and bulky. I broke up the led board and the resistor board into two separate boxes.
