Landing gear wires crossed

Last year my drone decided to slam into one of our pine trees and cartwheel down the branches to a hard thud. Sadly it was pretty beat up. I watched the videos and decided to fix it. I got the four compass wires mixed up and my aging eyes are failing me and the smaller compass wire is probably connected wrong.
Knowing this Should I send it back to dji or is there somewhere in the states that will help me out?
Also I would like to replace the gimbal screws as mine are somewhat stripped. Is this easy to order?
