Since fitting the engine back in with twin carbs the wiring in the engine needs extending. What core cable do I need to example to run from the battery to the alternator? Plus all the other small bits of wiring?
I don't know the VW specifics, but if you have a look at the VWP website http://www.vehicle-wiring-products.eu/VWP-onlinestore/home/homepage.php" onclick="window.open(this.href);return false; they suggest uses for each of the sizes of cable.
