Sorry, that went over my head and I really did not think of all the different jacket materials.
I am looking for wire that will be used for general use of lengthening runs for a bottle heater, various switches, gauges/controller and what nots for a nitrous system. I am not sure where I want to locate some of the items and I would like to have extra wires available if I decide to make some runs to the hatch or from the hatch back to the firewall/center console. THHN sounds like it would be best for the under the hood wiring, no? I hope this clears up my vagueness. Thank you for the help
