I bought 68250-08A 68271-08A both sets of numbers are on the Pdf for the leds module that fastens to the rack. It has mounting instructions but nothing on Wiring. It has three wires black, red and Blue. I assume black is ground. My bike is an older 98 EVO Road King. I really hate to miss wire and burn up something. My guess blue is running led and red brake led. Can the red and blue be tied together for a really bright extra brake light or wire it to my Custom Dynamics Triple Play Run-Brake-Turn module? Thanks
Black=ground
Red=brake
blue=running/tail lights
Harley has used those colors from umpteen years.
The connectors that came in the kit with the 2008 rack and light won't match up to your 1998. That's ok. Just find the tail light, brake light and ground wires on your 98 and bring them to the tour pak for the connection. Easy place to find them is the connector under the seat behind the battery.
You could splice things together. Could even do that at both ends. I hate making fixed connections though when something might need to come apart sometime. Find a local auto parts store and check their electrical section. You'll probably find some sort of pre-made wire connector pair you could use. If nothing else use a flat Whitaker type four wire trailer connector. They can be bought cheap in a pair so you'd have "both ends" and could easily splice one end in to the bikes rear harness under the seat while the other end connects to whatever pigtail you make that goes back to the tour pak.
