Any takers on having someone make this for me? I would pay for parts, labor and shipping of course

Actually I have been towing without it, and it really isn't a big deal not having the pressure switch. Perhaps some day, but right now I'm fine with the current setup.

Once again I will apologized to sag2 in advance for steering his thread away from his original intent. Since sag2 has toyed with the idea of not using a pressure switch in the circuit, and several of you members have expressed an interest in having this circuit "made up" for you, I thought I would supply this link from CF. If you read far enough into the thread, they do get around to building a press switch into the circuit.

It is a DIY w/pics that is straight forward and simple enough to understand for the common person. Hope this is helpful, and if I have strayed away too far from OP's content, feel free to let me know...I can take it :-laf . Jess

I have just read the link from Cummins forum. Definetely some good info there. Its just that sag2's design is exactly what I have been looking for in a lockup switch. To lockup when I want it too and the ECM can take over when it needs to. I have been looking at them since I got my goerend installed and have been on countless sites about lockup switches. I looked at ATS and BD lockup desvices, but they don't work they way I want and they are too $$

I understand completely, I am anal when it comes to my truck, especially electrical. Mine works great and without fail, My original gear shift button locks out OD, my #6 circuit locks in OD, and my #7 circuit locks my TC, in any gear, except maybe reverse...haven't tried that, and cannot think of a purpose...

The only thing I would like to change would be to place a guard of some type over the switch, to prevent accidentally activating with my knee or other, and a release circuit that would kick it loose if you had to hit your brakes unexpectedly, but then with an exhaust brake in use, it would also de-activate it, if you just touched the brake pedal for additional assistance in braking. Lot's of unintended consequences could arise while building these "mysterious switches" :-laf . Jess

OK, I may be interested in making a couple. I'm just getting ready to go on vacation so let me see if I can find a good source of relay harness while I'm gone and see what I can do.
