I built this GS dash for a stage 2 car I never finished. It uses a MSD 6AL, with numerous switches, relays, and status lights for elect. accessories. Includes Tack, two different oil press. Fuel press, gas gauge headlights and turning lights which uses a solid state relay I found in China that controls the blinking. Works great Dash has a master cut off switch and uses a push button for starting. The whole system worked great. Lots of man hours and bucks in it. Asking $465 plus shipping. If purchased won't be dis appointed.
