If you have bypassed the relay, and you hold down the button for however long you want the GPs to cycle...
Open the truck door.
Count the 'dings' that the little alarm makes. Those seem to be about a second each.
Regardless of how they are timed, just decide on a number of dings, and let that be your normal cycle.
Point being to know exactly how long you are cycling the GPs, instead of just guessing, or having to watch a stopwatch or something...
HEY! I wonder if I can get one of those little ding alarms, and just wire it in with the same button, so I don't have to sit there with the door open!!!
