Hi all , sorry for the delay on the trailer brake .
went to dealer and had them check out the computer to see if the plug under the dash was turned on , they looked at me like a dog tilting its head , said had to do with the ABS , blah blah . could find any issues and gave the truck back .
Now until then i had not plugged in the trailer , and still saw no activity on the trailer brake .
So after i had got the correct harness installed ,plugged in the trailer , Bang on came the controller and it works fine . YAY
So things i discovered since . oem plug is connected and turned on at factory if the truck came with the hitch and 7 pin installed .
The voltage coming from the brake switch is not 12 volts ( hence why my test lite did not work ) .
All new controllers go into a sleep mode when not sensing the load or trailer plugged in . So anyways all is good and look forward to yanking my camper around this summer
