I hate bending over and getting down on one knee and plugging and unplugging my block heater through the tow hook door. My 126 had the cord accessable under the hood. So I finally got around to adding an extension to access the plug from the hood (bonnet for the otherside).
I had a 8ft 16 gauge 3 prong tool cord replacement layng around. So all I needed was the female plug end ($7.00) from Homer. There is a small space behind the passenger head light to drop a cord down. Now I can access the plug from the under the hood.
