Originally, I was going to connect the strobes to the switch for the four-way flashers but decided against that concept.
As I was mulling over my (limited) options, my Senior Technician said: "Why don't you use one of the programmable outputs on the radio?"
Obviously, the radio cannot source sufficient current to run the device so the supply voltage must be connected via a relay. This allows the radio to output a low-level signal, sinking the relay actuator current and engaging it.
The relay is wired to the radio's accessory connecter:
And it is plugged back into the radio:
Now, into the radio's programming software. Pin 14 is set as an active low output:
It is set to toggle between its states and the states are assigned alias:
Finally, one of the buttons is assigned for auxillary control:
So, test it out and it works as expected - cool!
The seat is put back in. Fits perfectly without dragging on the supply:
Here we are:
I'll take some better pictures later on once all the snow melts. Perhaps a video is in order as well.........
