man i wish i found this thread sooner!! i started my install just by following the instructions like a sucker.. i have a 2016 cc 2500 slt with the cargo cam standard, 7" evic and the 8.4 radio. i got tricked by that short "wear-out" harness...
i pulled the wire through under the cab, connected power to the pin 13 on the TIPM harness, pulled the wires through the grommet and now i've got a terrible no-start condition!
when i open the door, the evic does not turn on. when i put the key in, i can see the gauges themselves wake up and move to zero BUT nothing happens when i turn the key!
i guess i must have knocked out a fuse or something while i had the TIPM flipped over to splice in the power line per the directions. Does anyone here know where i can start this daig. procedure? interior lights work, hood light works, doors lock/unlock with button on the door. basically nothing else works. fob won't lock/unlock, or start truck, no evic or radio with key in. i can't imagine that i've knocked out any computers since i didn't add any pins to any harnesses..
the only other thing i can think is maybe disrupting a connection while pulling the small harness through the tiny hole in the firewall grommet. Of course i've checked these all (i think).
any suggestions??
