servo problem...help!

[VXL TACO]

Hey guys, I just wanna clarify this. A few days ago I had a bad landing, and the Y-harness on my BL- Emaxx was caught in the spur gear and chewed up, part of it was still hanging by a thread, the mamba max engaged properly and the truck went forward and in reverse the right way, but when I tried to turn the servos would glitch REALLY bad and turn by themselves all the way to the right and keep making noises and twitching, but when I unplugged the Y-harness and plugged in one Lipo, the truck turned fine but did not engage the mamba max, thats because of the settings on it I know, but I think the problem with the servos is the Y-harness, so I just gotta get it resoldered right? Lol sorry for the long post, just gotta shed some light on this situation
