[QUOTE="Renomaan, post: 1332118, member: 22519"] I bought a dual airhorn kit from Amazon which uses two on demand air compressors, so no tank is necessary. Finding space on these Gen2 is tough! Here is a quick summary of the install with some pics I mounted the Horns behind the front grill The black plastic grate in the bumper pulls off without any screws I made a small bracket that mounts the horns horizontally with a slight drain angle I used self tapping #12 screws to fasten the bracket to the bent metal frame on the bumper I bought extra hose from Home depot with barbed couplers, I used crimp style hoseclamps from Mcmaster Carr-who wants to dig everything out later if a hose pops off? I made a narrow bracket from thin sheet metal and mounted both small compressors to it, one on ea side fastened the elex wires to the compressors with Faston crimp connectors. I slid the bracket with compressors thru the side black fender vent and bent the sheetmetal such that the narrow part of it came up under the top of the fender so I could TEC screw it to the inner engine bar area. The hoses and wires to the compressor run up thru the hood hinge passthru hole. --I can sketch out how this looks if anyone needs a pic--- Elex hookup: ==relays have 4 contacts, 2 things go on in there: the coil uses low current to throw the switch on the High current contactor.== I ran two relays (they come with the horns) one relay uses a trigger wire from the OEM horns ------lift the rubber flap to the left of the radiator and you can reach in and unplug the horn harness connector. Pull that up and tap a wire into the Yellow/Org wire and reconnect the OEM horn)-- This tapped in wire will active the coil on Relay one (other side of coil to GND). The switched contactor of Relay 1 will provide the GND for the coil on RELAY2. The Coil of Relay 2 will get triggered from an Upfitter switch The contactors of Relay 2 will throw the 12V 30A line to the horn compressors (in Parallel) The otherside of the horn compressor goes to GND If the upfitter sw is off the OEM horn honks If the upfitter sw is one both the OEM and the Train horns work Easy Install, took maybe 1-1/2 hr all parts for about $120....Horn kit $104...extra hose $20 Horn [URL]https://www.amazon.com/gp/product/B071NJB8HH/?tag=fordraptorforum-20[/URL] [ATTACH=full]119210[/ATTACH] [ATTACH=full]119212[/ATTACH] [ATTACH=full]119210[/ATTACH] [ATTACH=full]119212[/ATTACH] [ATTACH=full]119213[/ATTACH] [ATTACH=full]119214[/ATTACH] [ATTACH=full]119215[/ATTACH] [/QUOTE]
