Hi,HerrOtto!I used a 2-prong flasher,and eliminated the "P",(Pilot terminal).Reason being,is I wired in my dash indicator lights. B.T.W...Mine is a Grote 7-wire unit. I installed it with an A.A.W. wiring harness kit,at the same time.I wired mine to the "Hazard" flasher,so I could use my 4-ways without the switch on,or keys left in ignition. Hazard stays "HOT",all the time. Important,in case you break-down on the side of the road,and go for help. This way you can safely lock your truck,take the keys with you,and don't have to worry about thieves,when dealing with other mechanical problems.
