You are right you need one more cable from the engine to a ground on the frame in front; forgot about this one, thanks.  I ran mine from the front motor mount bolt on the block.  Two more ends to buy.

I also think that 6g is plenty for the charging wire and any bigger would be overkill.  Also I don't know how you would hook too big of wire to the back of the Alternator?

I'm running a 1/0 from the battery through the kill switch to the solenoid on the starter. The ground from the battery through the floor to the bolt on the kicker shock on the frame and a 2/0 ground wire with a 7/16 bolt in the frame to the block. I want to run a 6 gauge wire from the switched side of the kill switch to the fender wall solenoid to re power the car and ignition and a10 gauge to the starter to trigger the starter. I have 4 gauge I can run from the alt to the battery side of the switch. BUT can I use the copper stranded gas and oil resistant wire in a car?

Don't forget to put an inline wafer fuse between the alternator output and the battery.  This will pop in case of a crash or overload like the old factory fusable links.  For a trunk mount system I usually put one at the rear of the car and one up front to make sure that wire is dead in case of a crash as they are cheap insurance.  Sizing the fuse is based on wire diameter and length of the run.

Ive got a 150amp buss with a nice case like the one from RJM  http://rjminjectiontech.com/collections/alternator-accessories-1/products/alternator-charge-cable-kit I made my own for a fraction of the price. Ill put another one in the trunk if its a good idea but I don't understand why it will pop in an accident how will a crash overload a fuse?

I used to work at a car stereo shop and we did this on a regular basis.  I do not believe it is required by any sanctioning body but we did have a customer get into a bad wreck, t-boned I believe, and the 1/0 cable got pinched and it popped both fuses.  The fuel line split/broke and there was gas everywhere.  Not saying it was a life saver or anything but the customer was very thankful and ended up putting another system in the next vehicle at our shop.  Ever since then we just made it a standard part of an installation so I use that on my cars.

The other benefit of the wafer fuse is to calculate the load capacity of the cable and use a fuse just under that capacity.  If the system put a heavy draw on the cable it will pop the fuse instead of overheating the cable.

Darren the link I posted is that a wafer fuse. And should I put on on the battery side as well?
Thanks

I finally found the website I had been looking for the last couple of days.

http://madelectrical.com/

I am not saying you have to buy their gear to do the job but if you read what they are saying I think most people could piece this together to meet their needs and it would be safe.  If someone is not too electrically inclined then I would suggest buying their gear and doing it right and safe.

Pay specific attention to the part about how hard it is on the on board electronics using a disconnect switch in the trunk if you do not have it mounted correctly.  If you do not have the alternator wired back to the battery when the disconnect is used it will cause a voltage spike.  This is exactly what killed an after market fuel injection system on a buddy's road race car.  We could not figure out what the hell happened until we noticed the ABS module had gone bad as well.  John knows an engineer at Ford and explained what had happened.  It took the guy about 30 minutes and he let us on to what was happening and suggested taking a look at MAD's wiring diagram.  Took a few hours and the problem was fixed but it was costly.

I cant find anything on a wafer fuse. For now Ill stick with the fuse link battery connector and fuse on the alternator and when I get the coin I like the look of the relay on the hot lead to the starter
