I specifically bought the 4 pin version for my 2002 GMC Sierra 2500HD to replace the stock 105amp one. Run 14+ volts consistently all the time. Installed easily and has noticeably been performing better than stock for the last several months that I have owned it. Would definitely recommend for GM models.

Can't fully test the output until I install my amplifier and power inverter, but specs seem promising.
