StoneandSteel Posted February 20, 2025 Share Posted February 20, 2025 I’m trying to find out if there is a specific trailer wiring harness for my Mack Granite cv713? Hopefully a plug and play hookup.

0 Joey Mack Posted February 20, 2025 Share Posted February 20, 2025 On the back side of the coolant tank should be a buss bar with about 15 posts on it. Your trailer cord attaches there, and goes to the back. You will need a green cord with no plugs on the ends. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/75194-2007-mack-granite-trailer-harness/#findComment-569921 Share on other sites More sharing options...

0 Joey Mack Posted 2 hours ago Share Posted 2 hours ago see if the ledgend is still on the inside of the fuse box cover. it will show you the trailer circuits. I didnt realize this was a granite, thought it was older.
