I also added a compass and Eagle fishfinder/depthsounder. I replaced the inoperative 12V accessory plug with a rubber covered unit. You can see the new switch panel in the lower right corner.

I really like the look of these gauges. They have a stainless steel bezel and white face. They light up red at night. The compass is also backlit red.

A nice improvement over the whacky graph-style gauges so popular in the 80's.
