Connected my wiring harness from my Clarion Head Unit to the aftermarket adapter harness to plug into the factory wiring of my Durango. The HU has 2 yellow wires on it one with a 15a inline fuse marked "Memory Back Up Lead" and the other yellow wire has a 2a inline fuse and is marked "Bus Power Lead". Which wire to I connect to the Yellow "12 Volt Constant Power" wire on the adapter harness?

Thanks!

I believe the BUS power lead could possibly be for an accesory turn on.

My guess would be that the bus power lead is for powering components like fm modulators, satellite radio tuners, or video master boxes. i.e. anything that would be located relatively close to the head unit, and requires very little current to operate.
