Stop in for a cup of coffee

Thats kind of my thought process with returning the harness and going a different direction. While I could probably make a turn signal harness that'd work, i'd have more than the cost difference between this brand of universal harness and the slightly more expensive mopar specific one. Wish I'd found the mopar specific one before I'd ordered this one. Usually the mopar specific ones are 450-600 bucks, this universal had 2800 5 star reviews and was only 175. The new brand mopar specific one is just 235.
Maybe find a better used harness from something close to start with. Even if it's not right it will be closer than a Universal. Lay them both out and compare, change as needed...
