The following wire colors should be correct for your truck but check them
with a meter before making any connections.
The big red one is a 40 amp power wire that is always on. There are three
ignition wires, a pink wire with a white stripe, a pink with a light green
stripe, and a dark blue one. There are two accessory wires, both are pink
with a yellow stripe, one is 14 awg and the other is 16 awg.
The ignition wires are live in the run and start keyswitch position. The
accessory wires are live in the run and accessory positions. If you are
hooking up a gauge or something that is only needed while the engine is
running use the ignition wires. If you are hooking up some stereo equipment
or something that you would like to have powered without the engine running
use the accessory wires.
