    Enabling pin#42 in Hummer H2

    I’ll be doing the conversion from mechanical fan to electric one in 2005 Hummer H2 and to do that I need to enable pin#42. Can I enable this pin by HP tuners, and if yes do I have to get the Beta version to do so?

    If you're using the "Harness" once you have added the pin and replace the ground on the battery, you just need to set the temps. on the System dropdown under Fans.
