For color of lights, Red to the rear, Yellow t the front and the sides. The very rear running light if on the side should be red. I added extra side running and turn singal lights. These are the ones I put on the Monty.

They are a three wire which you will need for turn and running lights. They are bigger than the stock type lights. You will also need a turn signal converter, as if you just hook them up to the stock wiring, they will work as a turn signal and running light but if you apply the brakes they come on as brake lights. Also when wiring the converter make sure you have the right wires connected. Had a pre senior moment the first time I wired, had if backwards. Because it was wired backwards when hooked up to the tow veh, the truck was telling the there was something wrong with the brakes and would not let the engine start.

The wiring loom from the pin box runs down right next to the batteries and then into the belly, in a 1" black plastic split conduit. Just reach in the conduit by the batteries and find the green and red loose wires (left and right turn). Verify with a test light. T-Tap those wires with leads from the converter marked for left turn/stop and right turn/stop (T-Tap: connect to the factory wires, but let them continue to carry current to the factory taillights). The converter input also has a third wire for ground, which I grounded with the battery cable ground on the frame right next to where you are working.
Output on the converter is left turn, right turn, and stop. The stop wire is not used and should be taped or protected from grounding. The left and right output wires go up to the frame in the front of the compartment, then straight out to the LP compartments where the forward marker lights are. Remove the 2-wire marker lights and replace with your new 3-wire mid-turn lights (ground, marker, turn).
You will have to run wire for the mid turn. I used a 100 ft outdoor electric cord 3wire 18 gauge. Worked great takes alittle time to run the wire. Sorry but have no pictures.
