BEFORE YOU WATCH THE VIDEO DOWN BELOW - IMPORTANT NOTE!!!
PLEASE NOTE, in the video below, Dark Iron Diesel uses a different pattern to connect his SOTF switch, please follow OUR Connection instructions below :
Skip to Minute 6:15 for SOTF installation!
PRO TIP: If when you try to insert the pins they don’t stay in the gray connector...
If the red insert inside the gray connector is pushed too far down OR if you plug
the connector in and somehow push the red connector down BEFORE you insert
the pins, then you need to pull the red insert back out FIRST
To do this, you can either stick a hook or probe into one of the two bigger slots on
the red insert and pull it up slightly OR grab the small protruding piece of the red
insert with a small pliers and pry it up that way!
