Pretty easy to install and run cables/wires. Operates exactly as it should!
Only thing that might make this easier would be a small picture of normal mod location for the probe on various vehicles but that would be about it. I think it would help confirm what an individual will actually see and ease whatever worry or uncertainty before they drill a hole into their manifold.

Plugs right into the eas wiring harness. Load the egt gauge and watch it work. Installation was a breeze. Just need a tap and die.

Easy to install and necessary for towing
