I installed E-fans on my 2001

[ScottyBoy]

UPDATE: After daily driving my Suburban for the past 13 years since my Electric Fan swap, I have had zero issues. Thats over a decade of brutal Louisiana summers, countless road trips, including one trip that was over 3,000 miles total when I drove the family to Orlando.
The Electric fans are working just fine, and the fan harness has held up quite well. I was even in a collision a few years ago, and cracked my radiator mount, but the fans were spared of any damage. Lol.

One of THE best upgrades for our older GMT800’s!! Thanks to you, and some other members here documenting the process, I couldn’t be happier with the results, and ease of installation.

How do you convert from 4 pin to 2 pin alt?
