Wire gauge question
Looking at this 1988 manual, here it's specifically showing the R/V(squarebody) trucks. Am I reading this correct, that the first number is a circuit number, and the second number is a square mm cross-section?
If so, I can cross-reference that size number and come up with a AWG size. Link here. Reading those five wires in the middle of the screen, I come up with 22, 12, 12, 12, and 18 gauge respectively. Is this the correct way of interpreting it? Why did GM not list that 22 gauge wire according to its metric equivalent? Another unrelated question. Did GM ever install a factory trailer plug or brake unit in the squarebody trucks, or was it just up to the owner to set up his truck for pulling a trailer?
