yes in the above shot you can see where I brought through the cable it's neat and easy to get at on the other side.
No, i was thinking about lube but just about managed without it.. i used a hairdryer to keep the rubber sleeving warm as it was also freezing cold when i was trying to get the damn cable through...
oh and I also used a totally different sized (much smaller in fact just big enough) rubber grommet for the cable, the one Kenwood supply is ridiculously oversized and would require drilling a huge hole
