Just match what was used. Never measured it but think its 6mm

This may prove useful if you're in that area. https://club8090.co.uk/wiki/VW ... ain_cables" onclick="window.open(this.href);return false;

The other option (and some have done it) is to fit another relay so the demands on that cable are even less. I didn't go that route myself as starter circuits aren't the easiest thing to get at, particularly in the winter or when its pouring down and I didn't want to introduce more connections and potentially more failure points - just a personal preference. However, the principle is sound and I understand why some owners do it.

I think if I did choose to fit one, I'd make sure the relay was a really good one and actually inside the vehicle rather than underneath to ensure reliability and make it easier to get at. For now, a single cable works ok for me. Just make sure both ends are clean and sound and use shrink tubing ideally. Starter spade terminals are a notorious weak point on most v-dubs and do need inspecting properly at least once a year, relay or no relay.

Making an inspection hatch that you can open from inside the vehicle seems a good idea to me. Its better than laying on snow/ice. If I get around to doing that, I'll WIKI where the hatch should be cut and how.
