got to love the PDM60. makes wiring easy. i have my air horn set up for a ground trigger at 20 amps. and a 5 minute delay shut off for my dome light. easy to program the unit for what you want to do. and if you need help the folks over at the PDM60 sight are awesome to deal with.
power distribution module up to 60 amps total. has 6 circuits. you program it to what you want for amperage per circuit. only one circuit can be 20 amps. you can set time delay on and off. google PDM60.
Am I looking at this right that you could only have one circuit on the ground trigger? So basically you would still have to run a relay on everything or have the power for the accessory running thru your switch?
