1997 Automatic 47re
Okay I just got my mystery switch hooked up thanks to all of you but I have one question. I made it where I can unlock manually, lock manually or run stock, so I had to cut the orange and black wire. It seems to work okay but as soon as I got done I noticed if I turned my key on and then back off I could here a buzzing for about 3-5 seconds and then a click, seems like from the drivers side battery area. I did not here this before so I disconnected the jumper wire for the relay and the buzzing went away. What is making the noise? Is this normal to happen after jumping the relay? Do I have to jump the relay or could I just put it back in? Thanks for all of the help hooking it up.

 

When I installed the mystery switch the converter would not lock up unless the switch was thrown. No normal operation. I did jump the relay.

 

Best I can say is make sure you wired it right... Don't always trust what some people say as the three position switch is a little trickier than the usual two position.

 

What is a mystery switch?

 

It works fine now I just put the relay back in. Thanks

 

The mystery switch is to manually lock your torque converter. I also made it where I can manually unlock it or let the truck do it..
