I decided to try running the wires both toward the back of the gun. What was happen in is that the wire toward the front of the grip was keeping the motor from moving in the right spot after the bottom plate was installed. Basically after you installed the plate it would try to line the motor up but couldnt because of the wire.

Thanks for all the tips guys.

Oh bugger, I guess I saw this post to late haha. The last time Cushak and I worked on my M4 we had trouble getting the motor to seat the way I usually do my wires in the grip. He suggest running both wires along the back of the pistol grip with the red wire bent and looped in a half U where the grip aligns with the mechbox, before running it up the back, motor dropped in perfect.

I did that once, had I seen this post earlier I could have told you lol
