H4 wiring harness upgrade

when talking diameter as in 6mm automotive wire, is that total diameter(wire + insulation) or just wire diameter?
also, i've read single core wires are meant for stable environment, not cars as they vibrate alot thus use insulated strands of wire (can flex better).

It means the wire, plus the insulation - the diameter of the outside of the insulation. They are multi-strand cables - 65 strands of 0.3 mm copper.

where can we find 10awg wire lol. ebay sells per 50m roll.

Here you are - red and black 10AWG (6mm) wire, Qld seller, $2.50 per metre, sold by the metre:

jaycar only got 8awg wire (DC power cable)
total diameter 6.5mm
wire diameter 4.05mm
wh-3060

Yes - you can use it, but it's a bit too thick. The same wire is also sold at Altronics and DSE. Jaycar and DSE also sell 12AWG (5mm) wire - see one of my posts above for the catalogue numbers.
