I've got the ARB twin compressor and underhood mount kit from @4x4TruckLEDs - and am doing my homework for the install - but I can't find any videos for how to hook it up using the factory aux switches.. I just realized that the highest amp switch is rated for up to 30amps, but the compressor has a max draw of 50amps.. so it's looking like I won't be able to use an aux switch for this - is there a way around that?
Here is how I wired my ARB pump.
1. The Aux switch is used as a signal or trigger switch that enables the ARB switch next to the pump. ( This requires I think 8 amps from ARB,
Therefore any of the 10 amp Aux switch’s will work).
Note: **** the main 30/50 amps to drive the pumps is coming from two large amp fuses via the Battery included with the ARB wiring harness)
Also… it lights up the ARB switch to let you know it is “enabled” (see pic).
Why????
It is paramount that you have the engine running when you start up your ARB pump….
This will save your battery…the Aux switch ONLY works with the engine running.
Using the Aux this way acts as a Safeguard against accidentally turning on your pump without the engine running…(which is easy to do)
2… the pump is wired directly to the battery via a relay that comes with the switch.
3… the ARB switch controls the pump
(Wired plug and play as per the ARB directions).
Also… I originally ran with the air outlet on the pump located at an angle (as everyone does in the videos) and discovered that my roof insulation felt was hitting the valve….(not cool!!!😡)
**** (side note) Not that you need to… but I relocated my outlet valve and switch…. I purchased the switch mount bracket kit from the makers of the pump bracket… now nothing comes close to my hood insulation…
