From what I have been reading the '03 - '06 grounding is not great and the '07+ models changed that. Also, the purpose is mainly for the ManuMatic mode since shifting, whether up or down, has a lag. With the manual transmission people said they don't notice any change, but with the automatic there is during the manumatic mode. Even if I use wire and do the grounding myself, it doesn't hurt, it's pretty much an extended version of the Big 3. I do get your point though, not all cars need additional grounding an alot of it is a marketing scheme, but some vehicles can use better grounding.
That's a bit expensive, I bought a full Kicker 4 awg kit for about that much which included distribution blocks, fuses, and 30 ft. of wire, I just need the grounding locations.
Just follow the main harness from the Computer, you will see a couple heavy wires come out of the harness to ground, just run an extra ground from the - bat terminal to those points and be sure to sand/clean them thouroughly. On all the rest, just use a good clean bolt on the motor & trans respectively.
Oh snap!! They really exist? That would be awesome for keeping the screw in contact with the screwdriver while I'm placing it!!! //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif
Trust me, I will. I don't information like this should be kept a "secret." But some people want to make money off of it. I don't blame them and the only way they can do it is by not telling others how to do it. I'd post it on the G35 forums, but I might get banned or post would get deleted since one of the Admins sells a kit there and instructions are copyrighted or something...but that doesn't mean I can't state steps in my own words with my own pictures //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
