Like the previous posts on the other site have stated, it's just an older, cheap, genaric controller that is not worth messing with. The aggravation of feeding the wires back thru the holes would be a non-starter for me.
Controllers are getting better all the time and even today's basic models are way better than that POS.
Elifebike has an Ebay store and offer smooth, quiet controllers w/ Displays, PAS, cruise and timed turn-off, all for $30 to $40 shipped;
