I've got to do a little bit of rewiring and finally properly loom up the engine harness. In the past I've made due with sub-par solutions or reused harness wire. This time I'd like to purchase and stock myself up with some automotive grade wire that will be at home in an engine bay. I could buy from Summit Racing or something, but I wasn't sure if anyone had any good tips. I've looked at DIY Auto Tune and found something that would work but I don't need nearly that much wire nor do I need the labeling to confuse things.
Where should I buy wire from?
And on a related note, where should I buy heat resistant braided loom, and also larger sizes of heat shrink wrap?
