Hey guys, first off does anyone have or know where i can find a set of directions to do this mod? i found this one http://www.guzzle.rbmicro.com/tclock.html but I like to look at a few and compare notes. Secondly, which wire from the PCM controlls the T/C?
thanks alot guys!

I remember a couple of months ago RÖENTGEEP was talking with someone about ways to do this mod. Do a search with post by him and look.

 

You simply ground the purple with yellow stripe wire to lock the TC when you want. Cut the wire and there is no TC lockup, leave alone-acts as normal, and ground the circuit-Manual Lockp. I have yet to do this mod but I will soon.

Thanks guys, do you know if the OD off light will blink with this mod?

 

Im not for sure but i do believe it does blink when the computer tries to unlock it and you have it locked.

Jboard is correct just hook a wire to the purple and yellow wire. Then just hook it to a switch. All it takes is a ground for the TC to lock. Dont flip your switch to lock it under 25mph though, it can cause the truck to stall, and defanitly do flip the switch sitting still or at a stop light, this is about like dumoing the clutch on a standard. I havent found too much use for the mod though, but if making a exhaust brake out of the EBPV then the TC mod is a must and works good.

 

ruger, does ur OD off light blink with this mod?

 

No the od light should never blink, if it does you have a problem or got the wrong wire.

Hey thanks for the help guys! today i climbed under the truck and found the purple wire w/ yellow tracer and spliced into it and ran it into the cab. I have a spare toggle switch in the cab with (power, load and ground) so i connectedted the (Power) to a ground and connected the wire i tapped to the (load) and left the ground empty. Flip the switch and t/c locks up. Works great. again appreciate the help.

EDIT: as a note, the od OFF light doesn't blink as a result of this mod.

 

now do you just splice into it or just cut the wire in half?

ohh and where did you find that wire at? i would like to do this next when i get my truck RUNNING AGAIN.

I just spliced into it and ran the wire up to a toggle. To find the wire, crawl under your truck and look under the driver side frame rail. There should be 2 sets of wires wrapped in that plastic insulation stuff. 1 set runs back further in the truck, and one runs to the rear of the trans. Find the one that goes to the trans and carefully start picking through to find the purple wire w/ yellow tracer. (to me it looked brownish/purple) hope this helps! good luck!

after you do this mod do you have to manually lock the tc everytime you drive it or does it still lockup on its own

 

It will still do it on its own thats why you just splice into it.

 

what use would it be helpful to me is it worth doin
