the receiver has 5 essential connections: grnd. power, ignition OK, relay to amp, and ? I forgot....
the harness includes Bluetooth, several links to Area 51, and X
so what can be done is wire directly to battery n ground with real Ga wires, solder a male RCA, wire up the receiver with permanent conections...eg 2 short Streetwires audio cables, n link to those males with a double end female RCAs
so when parking at the boat ramp or trail head, the unit pulls from the instrument panel n goes back into cargo.
A 2006 Kenwood Replaced the 2006 with a 2016 finding the 1 does not have a users equalizer. The unit was wired in with power grnd to batt where the 2006 was wired into Ford's system.
The direct wiring sounds significantly better than the Ford system.
could be from XM not moving fast into distorting my sound channel #1 but having a custom electric system outside Ford's I went with the direct approach.
ordered a batch from Amazon.....the cheapies...there are 2 here in a box for tv camera video rearview mirror...so prob buy more from amphenol.
