if you can get a cheap grounding kit, sure go for it.. mostly grounding "kits" are just cheap audio ground cables marked up 5 times what they otherwise cost. all you need is large diameter cables.
i outlined what needs to be grounded in the first post. anything more than that is too much. if you buy a grounding kit, throw away the silly "distribution block", as its worthless, and just use a couple cables out of the kit. ground the block to the chassis, and reground the negative post to the firewall. clean up the factory grounds and you're done!
the factory toyota grounds really are good enough.. but things happen, especially with older cars! the extra 2 grounds ensure that things dont happen and you enjoy your car for a long, reliable time
