I've searched all over trying to find instructions to wire a torque converter lock up switch on my truck with no luck. The problem is my truck is a 2003 with a 47RE tranny. All the info I found is for 2003 up 48RE or, the 47RE in lower year models. Can anyone point me to instructions specific to my application? Thanks!

Wire it the same way, there is no functional difference between a 47 and 48RE transmission.
