Alex3000 Posted July 26, 2017 Report Share Posted July 26, 2017 I am about to rip out all my stock wiring as well as all the hacked up wiring I've done over the past 4 years of racing. OK, I have tried reading all the internet sites but I am still uncertain about "proper" wire gauges. DISCLAIMER: I understand the wire gauge charts. Proper wire gauge in a 12v system is determined by length and required amperage, blah, blah, blah. But look, I don't want to buy 10 spools of varying gauge wire and then measure every single piece I run. So aside from the obvious heavy duty items, can I just use 16 gauge for all my crap? Is there a downside to having too large a gauge? Lets say something only pulls like 1 amp, and would only call for a 22 gauge wire. Would there be a downside to using a 16 gauge? Finally. Does the wire gauge matter for ECU wiring? So for an 02 sensor to ECU, or Injector wiring, or whatever sensor to the ECU, would 16 gauge wire be fine? or might that cause too much resistance?
