GM Wiring Sizes

[FirebirdGT]

GM wiring diagrams refer to wire sizes as: .8 YEL, .35 PPL, 3 BLK, etc. The wire color is obvious, but what is the wire size? NAPA sells wire by gauge size: 14, 16, 18, etc.

Re: GM Wiring Sizes

GM like to use metric so

0.8 = 18
0.35 = 22
3 = 12



Metric Wire Sizes (mm 2) --- AWG Sizes

0.22 --- 24

0.35 --- 22

0.5 --- 20

0.8 --- 18

1.0 --- 16

2.0 --- 14

3.0 --- 12

5.0 --- 10

8.0 --- 8

13.0 --- 6

19.0 --- 4

32.0 --- 2

50.0 --- 1/0
