Hooking up lights is very simple. You can use any switch like a toggle or rocker switch. I run the wiring to the switch then straight to the battery. Mount the switch on your control panel or somewhere convenient. A toggle switch only requires 1 hole to be drilled and you can get toggles that light up when the power is on.
My son likes wiring up stuff so he done these for me because I am away from home right now.
These would work good on the TT control panel. I use the same switch as a nitrous activation switch on my racing quads. You only drill 1 hole to mount it and it looks clean and professional when you are done. Red LED Light Carbon Fiber CAR Automotive Illuminattoggle Spst Toggle On/off Switch Button
