I'm not sure which years GM went semi-metric. But if you're trying to determine wire gauge on your truck's electrical schematics, and you see numbers like ".8" for small wires and "3" for larger wires, this will help.
US wire gauge and Metric equivalents. (Metric size is in square mm.)
10 ga = 5
12 ga = 3
14 ga = 2
16 ga = 1
18 ga = .8
20 ga = .5
For example, on my 82 C10, "3 RED-2E" is a 12 gauge red wire running from the junction block fusible link to terminal 2E on the bulkhead connector.
And ".8 PPL-92" is a 18 gauge purple wire running from terminal 92 on the bulkhead connector to terminal 92 on the wiper motor.
