I am installing accessory lighting switch on my 08 street glide, i know where the three wires of the switch goes in the electrical socket and the aux light wire goes in the # 4 slot in each of the front signal light connector as per my electrical manual. What i am not sure is the Aux accessory switch. What is the aux switch connected to on your classic? Where would you find the hookup for this switch?
I use my Accessory switch to power the air pump on my Road Zeppelin seat. The Accessory plug can be found under your seat just in front of the battery. It's a gray four pin plug with a black rubber weather proof plug on top. Good Luck... "D"
