What are the Wire Functions for Pig Tail Wiring Harness for Optronics LED Tail Light STL23R24B

Question:

I have a 1969 Chevy C10 that I custom built a rear bumper for. I installed the STL23R24B lights in the bumper and need to know exactly which wires to connect to which as I am in the process of installing a new and updated wiring harness. There will also be another set of LED lights to be connected with these as I also am installing a set of Chevy Bowtie lights in the same position as the originals only with custon mounts to make them Frenched in. The wires going to the back are as follows,yellow is left rear turn signal,brown is running lights and green is right rear turn signal. Will I need to install a diode in line between the lights to insure proper operation? The bowtie lights suggest you install one to insure proper voltage and blinker operation as LEDs do not require as much amperage to work as filament bulbs do as you know. Any and all suggestions will be helpful as this truck will be a show truck when I am thru with it as there is a lot of custom fabrication involved in it. THANK YOU!!

For tail light # STL23R24B you should be using wiring harness # A47PB which has the following functions:

White is ground and will attach to truck frame
Red is turn signal/brake lights and will connect to yellow wire on left side and the other light red wire will connect to the green wire for the right side
Black is running lights and will connect to the brown wire.

The one running light wire will go to one of the lights. Then you will splice in a jumper wire from one light to the other to get running lights for both sides of the truck. No diodes required. If you have a hyper flashing situation you would need load resistors, # DI34ZR, on each affected circuit, not diodes.

The load resistors create more power draw to compensate for the low amperage draw of the LED lights.
