Thanks man. That would be great. In theory if I did go the 2 antenna route would I be able to replace the included antenna for those antennas posted and just splice in the extra one and run additional wires?
And thank you to everyone else for the assistance. I misread the wiring diagram on my compustar alarm and the wiring I was hoping to use is actually a trigger to remote start the truck, not unlock the doors. I might just end up soldering wire to an extra fob I have to simulate a button push. I’m not so worried about locking as the F-150 has a door mounted key pad that I can just press a button to lock and arm the system (love that feature) this might be the way I end up going unless I can find a setting in the compustar DC3 to do what I’d like it to do!
