I just bought a 7-wire Grote unit,and I wired it into my A.A.W. fuse block,(grounded to the mast). The unit called for a 3-prong flasher-I got GREAT results with a 2-prong. If you wire for the dash indicators,(my choice),I was told not to use the "P"(pilot) unit indicator wire. This could result in your turn signals looking like a railroad crossing. I used a "Hot" lead,not an ignition/accessory. That way,I may use my 4-ways without having to worry about "did I leave the blower running"? scenario,in case of a break-down. Did you try your bulb connection in the unit? it may have worked loose during shipping. Take your time,and check each wire for continuity as you go. If you lose patience,it's better to stop,and come back later. It took me 3 days,Grote tech said one thing,A.A.W. tech said another! Finally figured it out for myself!(P.I.T.A.),but I "got'Er Done".
