Mentally Unstable..
First off, I can not take credit in this all myself. LCAM-01XA, OLDBULL8 Trackspeeder all need a round of applause for their efforts in this!
All the mods are to be done on the transmission plug. The plug is located behind the little heat shield (held on my two 8mm or 5/16" bolts). BE SURE TO REPLACE THIS SHIELD WHEN THE JOB IS DONE AS THIS IS VITAL TO THE EXHAUST NOT MELTING YOUR TRANSMISSION PLUG!!
You will need to unplug the power plug from the transmission, cut or peel back the protecting covering on the wiring and locate the PURPLE WIRE with the YELLOW STRIPE.
NOTE: WHEN INSTALLING THIS MOD, BE SURE THAT WHEN YOU INSTALL THE SWITCH THAT YOU HAVE BETWEEN 12 - 14 VOLTS ON THE PCM SIDE OF THE SWITCH, AND BETWEEN 0.5 AND 3 VOLTS ON THE TRANSMISSION SIDE OF THE SWITCH. HAVING BETWEEN 0.5 AND 3 VOLTS ON BOTH SIDES OF THE SWITCH MEANS THE TORQUE CONVETER IS LOCKED AND YOU WILL GET A SURPRISE THE FIRST TIME YOU PUT THE TRUCK INTO GEAR!!
All instructions are in PDF format WITH appropriate wiring diagrams attached.
A HUGE thanks to LCAM-01XA for the write up and wiring diagrams!!
The First Mod is for those that want a two position switch. Lock and unlock. You have full lock up and unlock control via a two position switch.
This is what I currently have done to my truck and I got to say, it performs WAY better.
Basically, you find the purple wire with the yellow stripe in the transmission harness about 4 inches from the plug. Cut it. What you want to do is then extend the wires into the truck cab. I chose to go up through the floor where the transmission shifter cable comes through the floor, but it's up to you where you do this. I used RED on the computer side of the wire, and BLACK on the transmission side...it made the wiring easier when I was in the cab.
ALL FOLLOWING TESTING IS TO BE DONE IN PARK ONLY!!
Start the truck, and check for voltage on the red and black wires separately... the RED wire should have 12- 14 volts, and the BLACK wire should have 0.5 - 3 volts. Use a multi-meter and use the cigarette lighter outer ring as a ground..it's a perfect ground if it works. If this is the case, shut the engine off.
Find a spot to put your switch. I used a 2 pole, dual position aircraft style switch. My switch is located to the right of the WTS light in the 1992 and up trucks, but this is all personal preference.
Hook the RED wire to one pole, and BLACK wire to the other post. ALSO, you need to run a wire from ground on the chassis or body, to the pole with the BLACK wire on it, or the wire that is coming from the transmission side of the harness. It needs to see ground to work correctly.
Make sure that when going under 30 MPH, that the switch is UNLOCKED. Stopping may become harder and you can burn up the transmission in 1st and 2nd gear with the converter locked due to lack of lubrication.
Installing a BIG cooler is recomended as the torque converter generates a lot of heat in the unlocked position.
