Yes, you can use the 30 amp relays. I did this on my truck. The original switches were slow and had to be activated two or three times to fully lock or unlock. Relays corrected that problem. Used 82 and up switches with my original actuators and harness. I purchased a 5 pack of relays off Amazon, I think it was about $30. Used 2 relays on each side. Right 2 relays are the windows, left 2 are locks
