The cool harness mod is not what I need. I need to stop it getting to 100C point before the fans kick in. Out here when it hits 120F, its incredibly difficult to cool the engine down, its not a matter of fans turning on and it suddenly drops.

I need to make it so that it slows the rise.

So the cool harness mod is not what I need.

Also raising head pressures is the opposite of what I want. Increased head pressures increases condenser temperatures, which raises coolant temperatures, which raises condenser temperatures which lowers A/C cooling. Its a vicious cycle. Plus, I don't feel the need to contest with MB Engineering on pressures or reduce efficiency and longevity.
