Okay, looks like I was wrong - it wasn’t Amazon, it was Allied. I wired the HT for the CPC port back with my original Crossfire and then used the same cable I made then to get the Pro working. That’s what the 2nd post in this thread was referring to. The pinouts there are what need to be used.
I made my cable based on this thread way back for the Crossfire when I switched from my RW45 to the HT with machine torch.
I didn’t get the pinout tool because I had one but ultimately couldn’t track it down so used a small screwdriver to compress the tabs on the pins to get them in (& later out as well), a little harder than using the tool but still pretty easy.
This post has the pinouts you’ll need for the Pro.
This one has all the parts links in one place:
This shows which wires from Langmuir’s VIM connector cable go to which CPC pinouts.
@ntkfabworks original post is what started us all on making our own CPC cables. @bricklef’s post was a consolidated update of that one. I have a machine torch with my HT and needed the CPC port cable back with the original Crossfire because HT won’t fire the machine torch without one. Then I opened it up to add the wires from the short VIM interface cable you’ve got with your Pro. So coming out of the plastic CPC port connector shell you’ll have 2 sets of wires - one set that goes to the long trigger control cable and one short one that goes to the VIM box that you’ll mount on the side of your HT. I have them ziptied for the first 8 or 10 inches and then they split off near the VIM box.
Honestly, it’s 10 or 15 minutes work and you don’t even need a soldering iron as you can just crimp the pins. I think I soldered mine but only because I usually do, I don’t recall for sure now
