Well in case anyone else is wondering I heard back from Mark @ Probe:
The 9V battery connector that comes in the BT-05EL kit has a snap-type 9V rectangular battery connector at one end, and a 6-pin Molex Mini-Fit, Jr. connector at the other, so that it can plug into the control module at the same location that the power-cable harness plugs in when the installation is completed. Assuming you don't have the correct mating Molex connector housing, terminals, and crimp tool available, your spare 9V battery connectors won't get the job done by itself.
BUT, if the installation is already complete, you don't need the 9V battery to set the static timing...all you need to do is to disable your ignition coils, either by disconnecting the yellow & blue power-cable harness wires from them, or else disconnect the +12V applied to the coils' positive terminals. That way, you won't be pissing away battery current and making sparks while you set the static timing. When you're done setting it, you can re-connect the coils.
If the installation is NOT already complete, and you want to go in the order of the written installation instructions, you can connect your 9V battery connector to the red and green wires of the power-cable harness. The red wire of the harness connects to the red wire of the 9V battery connector, and the green wire of the harness connects to the 9V battery connector black wire.
The factory setting for the blue potentiometer is done by setting the time delay from the full-advance point at 1,000 RPM engine speed, using a test setup and an oscilloscope. But, if you're uncertain about the position of the pot, gently turn to screw to its clockwise limit, then its counter-clockwise limit, and set it at the mid-point. That will be close enough to get the engine running, then you can dial in the final idle-speed timing value using a xenon-flash timing light at whatever idle speed you prefer.
I'm guessing you have a copy of the installation instructions for your generation of the BT-05EL kit, or you probably wouldn't know about the 9V battery connector/harness for setting the static timing. If you do have a copy, you'll read that the static timing is set correctly when the red LED extinguishes just as the alternator rotor's full-advance timing mark(s) align to the fixed pointer.
Final timing setup is always done with a xenon-flash timing light, for both full-advance (rotating the pickup plate) and idle-speed (blue pot adjustment) timing.
