Here's what I do.

Look at the '63 wiring diagram,
http://www.thesamba.com/vw/archives/info/wiring/bus_63_USA.jpg

The gauge used for the oil light wire is 0,5

According to this page in the Wiring section of this site:
http://www.thesamba.com/vw/archives/info/wireconversion.php
0,5 = 20 gauge

So you should be fine with 20 gauge. From hacked Buses I have seen, a lot of people use 16 though, I think because it's commonly on hand.

Better to go a little big than too small...

If you have a parts bus you could cut up the wiring harness, usually the stuff in the middle of the long PVC tube is in great shape and is ideal for making repairs. I like to solder, shrinkwrap, and then cover the repairs with fresh pieces of PVC tubing. It takes a little bit more time but the repairs are pretty much invisible.

Greg said it best. Find a bay in a junkyard (where you'll find most bays anyway)- and liberate its harness. My engine bay now looks exactly as it should- and I have spare 'coils' of color coded wire for every future need.

If you look at the wiring diagram above, it looks like the largest size used is 1,5 which equates to about 15 gauge but I think 16 gauge will be ok for those wires.

I've had 16 gauge for some of those wires on various Buses and not had any issues.

Zombie thread warning =)

Hello Everybody. Im about to rewire the Double Cab.

Printed and studied the wiring diagram, conversion chart and I bought/ repaired most of the switchs and electrical related stuff.

The question is: The AWG 20 wire for the tail light circuit seems to be too thin
Is it a deliberate way to underpower the tail light circuit to make noticeable the brake light brightness? ( circuit with AWG 16 wire)

Im using the wiring diagram vw transporter from aug 1966.

Thanks in advance.

If it was too small the wire would run hot. No problem with that for us.

We likey zombies!
