2 months later, tis a breeze in time.
Ordered 2 electrocouplers - a 2" and a 1.74", turns out it's a 1.85" coupler, so the 1.74 is a tad short, and the 2" a tad big. Is it worth the shipping and another 15$ to get the right size, or is sizing down/up not going to be an issue.
On the question of replacement, should I detach the entire truck to do this? the coupler seems to be cable managed through it.
And does the coupler polarity matter? Left side on the bent one is color coded as gray, so I assume it's the hot, but the 2 replacement couplers are black/black
