Here is what you need.  I too was having trouble with those GMUpfitter numbers.  I contacted them and got this part number for a terminated lead (wire and connector), for like $11 from the dealership.  I used this to tap into the connector and send power to my CHMSL on my topper, worked great.

 

Just use the instructions from the upfitter bulletin and this part will allow you to hook up your topper third brake light properly without splices.
