914 wiring harness issue_wire size in MM, 914 wiring harness issue_wire size in MM Options

[johnorm]

Guys I have an issue that I could use some help on. I'm rebuilding my 1973 914-4 wiring harness using AWG GXL wire. I have a schematic for a 1973 but the wire size, in MM's, is not shown. I found, on the forum, a file called "914_Electric_74_Current Flow (partial copy of that file is attached). In matching it to my harness I found a major issue, IMHO.

Of the four Red wires coming from the Battery - two are noted as 2.5MM (10/12 gauge wire) and two as 4.0MM (these 4.0MM wires (6 gauge) go to the ignition switch and the other to Fuse 11).

My question is this a typo / I'm reading it wrong because I do not have a 4.0MM wire, in my old harness, going to the Ignition Switch and Fuse 11, all four wires are 2.5MM or 10/12 gauge AWG wire.

Second question, if I have room for 10 gauge in the center tunnel should I run 10 vs 12 gauge just to be safe? GXL wire has a thinner sheathing compared to old PVC wire that I'm replacing.
