What gauge wire should go to Duraspark module?

I'm in the process of cleaning up all the wiring under the hood which was a complete mess. I'm doing the Nutter Bypass and have removed all of the old computer wiring.

I want to do a clean install of the wiring and want to use Weather Pack connectors at the ignition module instead of the Duraspark connectors which leak and corrode badly (I've never pulled one apart that wasn't). Both of my female Duraspark connectors at the module are broken, anyway. The only issue I found with the Weather Pack connectors is they only accommodate a 12 ga. (thin wall insulation) or smaller wire. That's fine for the distributor wires, which are 16 gauge. However, the red wire supplying power to the ignition module is a 10 gauge wire (the one that's spliced into the ignition switch wire, resistance wire, and alternator excite wire). Is there a need for a 10 gauge wire from this splice point to the ignition module connector?

Reason I ask is from the Duraspark connector to the module, this red power wire is only a 16 gauge wire just like the others. Is there any reason that the short section of 10 gauge wire can't be changed to 16 gauge wire?? From the Ford pics I've seen, it looks like they used 16 gauge for it all. (Not to mention the replacement Duraspark connector NAPA sells has all 16 gauge wires coming out of it.)

Is this OK to change?
