Harland, there are three things you need to understand about the lighting circuits on the Triton.
First there is a high current circuit. Power comes from the battery to a relay (LHS of engine bay) and then goes to the lights.
Second, the relay is switched by an ECU inside the cab which activates a low current relay that earths the circuit from the engine bay, activating the high current relay there.
Third, the ECU takes its signal to activate the low current relay from the stalk switch. This is a very low current circuit.
You should NEVER use any wiring inside the cab to power auxiliary lights. None of this is designed to carry the loads that are generated by spotlights or light bars. Some is positively switched, some negatively. Some operates on voltages well below 12v and some of the switching is momentary. Unless you really know what you're doing you risk blowing fuses at best or, at worst, blowing up an ECU. At $2.5K each this can become an expensive mistake.
Hopefully you've just blown a fuse. Check all the fuses in that block under the dash. Many of them are connected to circuits other than what is indicated.
The correct way is to take power to switch a relay from the circuit between the high current relay and the headlights. Blue/yellow wire to the left hand headlight. On some models you have to splice into this circuit behind the headlight, others have a socket that you can plug into. Either way, use this to switch a relay which draws power from the battery, through a fuse.
This is the circuit diagram for the headlights:
This is how you should wire up your auxiliary lights:
