Switch for Torque Converter

My buddy has a 2001 Dodge with a Cummins and when he bought the truck it had a switch that he can manually lock up the torque converter. I have a 2000 Powerstroke and I was wondering if anyone knows if i can put the same type of switch in my truck?

Do you pull the wire out of the PCM or splice into the purple w/ yellow wire?

Splice it if you dont mind the od light blinking on the shifter, go and and do guzzles mod if you want it all clean and pretty. Just peal back some insulating, or use one of the those wire joints, blue in color, you can dead head a wire on one side, and leave a run through wire on the other. Then run to your switch, then ground. Sorry, dont have any in my office to snap a picture of .http://www.tessco.com/products/displ...85&eventPage=1

Found one

Preferrably solder and shrink-wrap the connection...."scotch-locks" are a sure way to end up with high resistance and corrosion problems down the line.

Ya I just looked at the PCM wiring and there is a lot of wires!!! Any idea on how to locate the correct wire for a 2000 PSD? There are three wire blocks that go into the firewall and then there is one wire block that goes into the computer board. Any idea what block?

I subscribed to www.alldatadiy.com to get schematics, pinouts, etc for my truck. Might want to check that out. I just looked and it says the violet/yellow wire is the torque converter clutch solenoid on the 2002 at least.

Thats what they say. I tried to use those blue connectors you squeeze that you dont have to strip the wire before hand and they must not have worked. I am going to try to work on it more tomorrow night. That wire is a little difficult to find. Mine was in hole 54. Also I think I am going to cut the wire and soldier it back together because that wire is a really small gauge. Will update more tomorrow night after I work on it more.

If you pull alot you can also do the EBPV/ eshaust brake mod.https://www.ford-trucks.com/forums/2...brake-mod.html

I will be doing this when it warms up.

It does show every connector and a general location of that connector if that's what you mean. This wire is on the main connector to the powertrain control module.

It looks like you would not want to ground it all the time... you can't have the torque converter locked up all the time. Just ground it when you want to be sure it is locked.

Yes I understand that. I am pretty sure I found the correct wire but I couldn't seem to get it to work last night. I think it was those blue squeeze connectors that are the problem. Going to look at it again tonight.
