Matt, I left one of mine dangle from its wiring for 3 months of summer while driving around with a spare in the cubby. Mostly I wanted to see for myself how little heat they really generate in use, as I suspected, given all the hand-wringing over heat sink compound being done on this board.

It (on its original heat sink and compound) got warm, especially after a long drive, but never warm enough to be uncomfortable to hold in the hand tightly, meaning its dependence on the fender for heat dissipation is nil. And as already mentioned by Kitty, the ground is through the harness, not the heat sink.

No worries...
