Hey all. I just wanted to post this for other peoples reference in case they decide to do the BIG 3 upgrade to their Coupes. The following pics show the most convenient places to fasten the wires. 1/0 gauge wire should used. 4 gauge minimum to add to or replace the stock 8 gauge charging wires. It's much less work to just add to the existing wires and it keeps the stock wires in place in case you want to remove the added wires later. Not to mention the more wire the better. This will make your alternator more efficient for those big stereo installs. Once I did mine I noticed a substantial improvement. Less headlight dimming to be exact.
BIG 3 wire #1 - Battery negative terminal to Chassis

BIG 3 wire #2 - Engine Block to Chassis.


BIG 3 wire #3 - Alternator positive terminal to Battery Positive terminal. Route this wire through the existing fuse in the fuse box. Fuse terminal on the right in the pic/closest to front of car goes to the Alternator positve terminal. Fuse terminal on the left in the pic/closest to the back of the car goes to the Battery positive terminal.
