Hello I’m trying to add a switch to my aftermarket actuator. I have a compustar alarm/ remote starter. I have keyless entry by adding the aftermarket 2 wire actuators. When I wired the switch, a 7 wire switch , it works for a few times then blows the fuse from the added fuse box I added for my accessories. If I disconnect the actuator from the harness that I made to go to the alarm/ remote start brain, the fuse does not blow. Do I need to add a diode to keep it from blowing? If so where do I add it?

Thanks

Need more information. What compustar do you have? What aftermarket actuator? Does it (actuator) have a module or relay setup that goes with it? How is everything wired up/do you have a wiring diagram of your connections?

You don't need a diode but you do need to have things wired correctly so that things work without having a direct short condition which is what is blowing your fuse.

You can't use that relay setup with that switch directly controlling the actuators. You either need two additional relays wired like this https://www.the12volt.com/relays/relaydiagram2.html or you need to rewire the switch to control the relays and not the actuators - Pin 2+5 to negative, Pin 1 to relay alarm (-) unlock output wire, Pin 6 to relay alarm (-) lock output wire, no jumpers.
