Still wiring the car and made it to the FI harness. Mostly all is well but I'm stumped on getting the ignition hooked up.

It's all Holley stuff on a BBC:
Dual sync distributor
Hyperspark 2 ignition box
Hyperspark coil

The distributor connector was obvious enough but there's the points trigger wire on the diagram going to a random spot and it looks like I'll need to source a few terminals and seals to go with the connectors. If anyone has sketched this out before or can help me out I would appreciate it.

Is this what you need? I have used this a few times to do what you are describing with a hyperspark distributor.

Nope, the distributor is already plug n play. I thought everything else was too.

I called in to Holley this morning and maybe have it straightened out. Basically finished the regular rewiring of the car this weekend and my brain shorted out when I laid out the ignition components.

I actually got some follow up info from Holley later on from the same tech support person. There was a harness pigtail included with the ignition box and immediately made everything make sense.
I think I was just tired of staring at wires at the end of Sunday.
