I just installed my Stillen Grounding kit, took about 30 minutes. 25 of those minutes were forcing my arm up into the space to reach the 14mm rear engine block bolt from underneath, with a universal (cardan) adapter on the socket. Rest was a piece of cake. Started the mada up and... no difference at all?? Removed the grounding kit, bought a micro butane torch, soldered all the crimped connections, reinstalled the grounding kit, (only took 8 minutes now that I'm a practiced contortionist), and cranked it up. Results- much more stable charging system readouts, faster starts, and so far (down to 30 degrees F) all the voltage related light quirks disappeared. (anti slip, vdc, flashing dash lights when it gets below 40 degrees, anti lock and traction control spurious engagement). Only complaint is that for what I paid Stillen for $15 worth of wire and eyelets, you'ld think they would solder all the connections. A regular soldering iron won't heat up the wire or eyelets enough to generate a total solder set and connection. The micro butane torch took about 3 seconds per connection to heat and solder, and it only melted the plastic insulation about 1/16th of an inch back from the connection, but since it's a ground connection, no biggie! A definite recommendation on both counts. :)
