Okay so I am at throttle side. I thought it best to pull tbw extension first and of course all went well. The problem now is trying to pull the secondary bunch of wires through. I have added dish soap as suggested but the namz wire extension has a bulge where the connectors meet and with the heat shrink it does not want to travel around the 90 degree turn at the bars. I have 14 LA chopper twin peaks by the way. Any tricks or advice much appreciated.
