I always squirt some WD40 into the truck side connectors and wiggle around some to make a good connection.
I also have one these in my RV TOOL BOX which plugs into the truck side trailer connector and this will tell you if the proper signals are being generated from the truck side. Helps you troubleshoot better looking for the cause of the weird lights coming on.. I got mine from AMAZON but have seen them for sale at regular truck parts/accessories places..
