For saftey reason and protecting your investment if you ran the ground (Black) wire directly to the battery. You should install a fuse on the black wire at the battery with same rating fuse as the red.The 4550 works great for the local DMR repeater, and even though it is on the driver's side of the center console it does not get in the way. My leg doesn't even touch it.
It is wired direct to the battery with switched ignition sense ... turns on when the car is started and turns off when I shut the car off.... I highly recommend it!!
Using a block of wood that is cut to fit the storage compartment and the I angled the wood and attached the clip to the angled side.How is your HP-1 clip attached?
