Hiding the wires in engine bay

Remember this, always run a ground wire from a trunk mounted battery to the engine directly. Do not use the chassis for your ground cable. Also run at least #1 ga or 1/0. Welding cable should never be used in a car as it does not meet the insulation temp and spec of car wiring. It may be cheaper but not a good idea. I have done a lot of research on this and the best source is the Ron Francis catalog. It is an encyclopedia of do's and dont's. Not much on the web site but the catalog is a bible for wiring. PM me if you need some cable. I am running battery cables inside the car on my 69 Dart. Your Valiant looks great, like the way you did the wiring under the fenders. Is that conduit?
