i used a jr servo extention with plugs.i used a six inch,it is a bit longer than needed,a 4 inch would be perfect.3 inch would work as well, but i like to have slack in my wiring.the tekin esc plug just came to the rx box so i couldnt tuck it in the box.but it looks good and is not exposed at all.

my center diff doesnt seep anymore after doing the sanding tip. i love when things i read on hear help.thx guys for the tip.
