How do I connect to kill three winches via a FIA kill switch?????

Does anyone have a wiring diagram for wiring a FIA kill switch that will kill the engine and also the winches which I believe is a MSA rule for extreme challenge events? The FIA kill switch is easy to wire/connect it’s the supplies to the three winches.


There must be an easy way to do this? As all extreme boys must have this, for the life of me I can’t see an easy way to do this without a load of bits contactors etc etc etc


I have the three winches through isolators but want/think they should all be controlled via ONE kill switch or am I wrong? I am running two alternators.


I am in the process of tiding up the wiring on the landy hence asking the question.

Even if you have 4 solenoids, three for the winches and one for the engine stop, you can easily switch those solenoids to the off position with another solenoid that is controlled from the kill switch or directly from the switch if the power consumption is minimal.
Kill switch live to each solenoid actuating terminal and earthed out. When you turn the kill switch off the solenoids open and cut the power.
