I wired mine a few years ago using stainless-high temp jacketed wire, soldered and heat shrink on every connector. I wrapped the groups of wires in 3M electrical tape, and anchored them with adel clamps, riv nuts and stainless screws. I have a lot of heat and have had not issues whatsoever. The wire groupings are along the upper edge of the firewall and fender liners. Neat and accesable if necessary. The 3M (Best) tape holds up well to the heat.
