My 2002 TC lock-up switch "MOD" is working GREAT!

BUT

My brother just bought an early 2003 Ram2500 with the 47RE tranny. My help question is how do we install the Switch on the 2003???? I have read all the posts and some say use the 33ohm resister and you don't need the relay jumper, others say you need the resister and the relay mod. Whats the correct answer?
If we need the relay mod, where is it located ( in detail )??

I did mine with a momentary switch and a fabricated a pistol grip type assembly for the switch.

Thanks for any help, this is a great mod if used with TLC

 

use the search ... I think I remember 03 don't lock...stock anyway
