gunrunnerjohn posted:The coupler connector is the standard JST EH family 2.54mm connectors used on a wide variety of TMCC stuff. I finally "bit the bullet" and bought a stock of them with the pins and a crimp tool so I could whack this stuff out custom. You will only need one wire to the coil coupler as the other one is already frame grounded, right? I forget without checking, but one side of the coupler connection on the AC Commander will be frame ground, run the wire from the other one to the coil coupler.
If you zoom in the photo I posted above after I placed the electronics into the engine you can see the front coupler connector on the far right of the AC Commander board. As you're looking at it in this photo the left pin is the power. Before I put the board in I looked at the tracing on the back and the common pin [pins #3 and #6 on the connector between to the coupler connectors as shown on page 5 of the AC Commander manual at http://www.electricrr.com/Manuals/Ac-V5-Inst.pdf ] seemed to be on the same board trace as the right side pin. You can see where I put a black dot under it in the photo above so I could remember the common side once it was put together. In that photo above you can also see where I've put a little piece of black heat shrink tubing over that common pin (didn't apply heat though) so I could temporarily wrap the wire from the coil coupler onto the left pin without shorting. Tonight I'll attach my legacy base to my test track and try the board out under command control, including the couplers.
GRJ - If you can make me two connectors with a green wire attached I'd be happy to pay you for them.
