u/Frashure11

I have been planning out a new harness for an old truck of mine and came across an issue. The receptacle I was planning on using for sending power to my relays is rated for 150 amps total but the largest wire its connector supports is 14AWG. All my relays are within 14 AWG usage for their amp draw except 1. I need to run a wire just 6 inches to the heater relay, but this guide recommends 10 AWG though it only goes down to distances of 3 feet. Hoping the distance is enough of a factor this one run can be an exception. Receptacle: SBB-12 from Deutsch
