What gauge wire ran to what ? Say on a 1953 bug

Example turn siginal switch to semaphores. What guage wire?

I need to know the whole car.

who ever comes up with the answer many thanks

Wiring digram I know. Gauge size I don't.

Will this help you? Its split.

How do I take the Cross Section sq. mm ---- to what gauge wire ??

I'd say that is how they are ordered, at least that was how they are sorted in our workshop at work...

from the site's Technical section: http://www.thesamba.com/vw/archives/info/wireconversion.php
or you could use Google to find numerous conversion tables.

ah, ok, in "american/english" units... :wink: I have never understood you keep using those hard to handle units, metrical system is so much easier as soon as you start making calculations... :D

Hello
Well, sq mm means square millimeters.
If you cut the wire sharp and look at the cuttet surface, thats the flat face,
given in square millimeters. It might be in the states in square inch for wires? So the thickness of the wires is given by their square millimeters surface when cuttet. Does that explain it to you?

There are no direct "equivalents for metric spec to AWG gauges.

The poorly formatted table below will show you the basic, nearest value conversions. Not that for some metrics, (like 2.5 mm^2) there is no direct AWG equivalent. If you are replacing wiring in this case you should "round up" to the nearest AWG value (12Ga in this case).


Gauge......Area
AWG.........mm^2

30...........0.05
28...........0.08
26...........0.14
24...........0.25
22...........0.34
21...........0.38
20...........0.5
18...........0.75
16...........1
__...........1.5
14...........2
__...........2.5
12...........3
__...........4
10...........5
__...........6
8.............8
__.........10
6...........16
4...........25
3...........35
2...........50
1...........56

For the uninitiated with AWG the larger the number the smaller the wire, ie 8ga is larger than 12ga.
