Re: Hella DUAL-TONE, 2 TRUMPET AIR HORN KIT Install (got_vdub)
Find a place you want to mount them. Make a braket to hold them. remove your horns that are in the car now. The air compressor uses standard slide on contacts, so no special connector is needed. You don't need to use the relay as our cars already have a horn relay and to wire in another one would just be useless and redundant. Cut off one of the horn connectors, and crimp the new slide-on connectors ( I have no idea what they are really called but can be bought super cheap at any auto parts store). Make sure you get the brown as ground (-) and yellow/black or whatever the colour is as (+). depending where you locate the horns you may have to add some wire. That's abotu it.
Also, change your horn fuse to 15 amps, because the stock 10 will blow right away.
