Upfitter / Aux Switch Wiring Explained

[BigJ]

I've collected info over the months on this subject, written by guys like FSM06, HarleyGuy, Junior and others. I've tried to condense is all down into a simple diagram, that even an electrical idiot like me can understand. Please double check me here guys.

HOLY CRAP! Its about time someone made sense of this. Very simple yet full of information. Thanks.

Nicely done J!:clap: Very simple and easy to understand, and the layout is excellent.

ooopps! only one correction......The relay for the No.2 Aux switch is actually in the position 10, not 8. No. 8 is the fuel pump relay.

Doh good catch FS. Fixed and first post updated. I also made it a little bigger (easier to read) and clarified some of the verbiage a bit.

Please triple check.

THat should eliminate the "how do I make them work" question asked all the time.
