This is what i just got done installing on my truck for my gauges. Plus there is still plenty of room for other items that i might install later. I did buy the 12 position with ground, made a bracket and installed in the engine comp. right behind the drivers side battery. Looks professional and room to grow. I different prices online but went to the local marine supply and they had it for about the same price. The one below is at West Marine: Home Page
