So I completed the WT mod and now how do I test for ac noise? I know I should have done this first but didnt think about it. I also know its in here somewhere but cant find it. Help a guy out.

    Same way you would before you did the W-T ground wire mod. So take your DVM and red probe you touch the BATT post on the alternator and then the black probe you touch to the passenger battery.

    On manual trucks the AC noise affects the cruise control like on my truck say I could set for 65 MPH and holding good for several miles then all of sudden it would surge up another +10 MPH from AC noi

Ok I know on autos this helps with TC lock and shifting and such but whats the biggest advantage for a manual truck?
