It sounds like you have the normal set-up: green wire for right turn and brake, yellow wire for left turn and brake, white wire for ground, brown with green stripe wire for right side running lights and brown with yellow stripe for left side running lights.

Using a connector like the Quick Fix (TM) 4 Pole Flat Trailer End # HMC20031, you can connect color for color the green, white, and yellow wires. As for the brown with green stripe and the brown with yellow stripe, these will both need to be connected to the brown wire on the new connector.

Load range B trailer tires are going to have a lower capacity than C load range tires. Basically that, psi rating, and the ply rating are the only differences. A higher load range tire would last a little longer than lower load ranges of the same…

The two sizes you mentioned are pretty similar and fit many of the same 15 inch wheels. The 205/75-15 fits rim widths of 5 inch to 6-1/2 inch whereas the 225/75-15 fits widths that are 5 inch to 6 inch. The 205 is 27.1 inches tall and the 225 is 28.4…
