I just received my Twin Hella Electric trumpet horns from BAT Inc. today and I need some help with wiring them up.

All that came in the kit were: two horns, one relay, two metal brackets, and a wiring diagram.

I jacked my car up and removed the horn and found that the horns are not a plug and play type of thing (which I kinda expected they would not be)

Does anyone know what strength of wiring I will need to use? or for anyone who has installed these, can you give me any tips?

Thanks

I used the existing wires. If anything get the blue wiretaps so you don’t have to cut anything factory off. From what I remember the horn wire is 18 gauge, just get some crimp on spade connectors and plugem into the compressor. Had to take mine off because water kept getting into the trumpets

Point them at a downward angle and facing towards the rear of the car. I had mine mounted up under the car near the stock horn location. Never had a problem with water getting in them.
