Hey thanks for the compliment! I feel really bad for Graperson not being able to locate the plug. The best way is to lie on your back and stick your head under the bike, right under the right footrest and all will be revealed. You just can't see it otherwise. Could try a mirror I suppose...

For those who've fitted the unit, I'm looking for feedback on how your MPG varies after installation. You should see a reduction in fuel consumption of between 4-7 mpg on the default setting.
