picked up a 4 gauge 40 inch pre made wire today, 30 inch should be the best fit, but they went from 19, 24 to 40 and then up from there, 40 inches is a bit long but not to bad.
it was just getting dusk as i put the wire on, and i can say the interior dash lights are a tad brighter, the windows move maybe a tad faster. head lights look brighter for sure, but we shall see for real later when i go to park it later on. aka in the real dark.
cost 8 beans.
