Ok, so I just did the battery-ground, and chassis-ground...and I'll just write everything I noticed/did.
I cut the wires, about 10 inches for the battery-ground, and 18~20 inches for the chassis-ground. Cutting them was a pain in the ***, but manageable. Stripping the ends is much easier, just use a good knife. It's also a pain putting the strands into the ring terminals, but also manageable. Just be patient, and it'll work out. Table vise works great for a strong grip. Also, if you have rubber ends for the ring terminals, put them onto the wire before you put the rings on. It's impossible to put them on through the ring.
Remove negative, then positive from the battery, then remove the battery. Trust me, it'll make it so much easier. You don't need to remove the tray. The V6 engine has a "chassis--battery--ground" connection. However, i just made 2 different connections chassis--ground, and battery--ground that connect to the same point on the frame (stock location, by radiator)
Use an extension and a ratchet to remove the chassis bolt (10mm.) It's wayy under, by the transmission..might even be on it lol. The stock wire is fed through some plastic coils which is attached to a small cip to the side of the battery tray. I couldn't for the life of me get the clip off, so I just cut through the stock wire and pulled from both ends.
Other than that, it's easy enough; just a matter of elbow grease. Also, try and route the wires away from heat sources for obvious reasons.
Oh, and you probably removed the coolant reservoir to install the ground bolt. Don't forget to put it back (like I did lol).
I'll take some pics tomorrow, and do the alternator-battery on Monday. If you have any questions I'll answer them as best I can...
