Engine/Transmission (1998.5 - 2002) Converter lock up switch?

[silver03]

Does anyone have the wiring diagram for the trans lock up switch. Which wire do you ground??

While you certainly have the right to do as you please, I would think long and hard before you by-pass the built-in protection Dodge designed into there power management system. The stock TC is at best marginal, in it's ability to sustain for long periods while under strain. The engineers built into the system, a way that allows the transmission to relieve it self of a load, if and when the time calls for it (about a zillion times if towing any load at all). By allowing the TC the ability to UN-lock, it enables the transmission the ability to survive. UN-locking allows the transmission to UN-couple during points of added strain, and also allows the transmission to help cool itself. Manually compromising this built-in safety loop, can and will lead to the early demise of your automatic transmission. Yes their are some that do run this type of hillbilly re-wire, but I would reconsider this though in the strongest of terms. In addition to the mechanical drawbacks, their is also a very serious safety drawback. Manually locking the TC and over-riding the built in safety features Dodge built-in to the system, is a very good method to the manifestation of an accident. By locking the Tc manually, you will deprive the trucks normal ability to UN-lock when needed, like at a stop light, or perhaps during an evasive maneuver on the expressway. It will act just like you have a manual transmission and you forgot to DE-press the clutch pedal, and in a time of need, who would have time or presence of mind, to reach over and UN-lock , turn off the switch? Know one!

Same thing goes for the transmission itself, by not UN-locking when conditions call for it, you over stress the many parts it was suppose to protect.
