I installed the 2/0 AWG starter cable tonight. It starts at the output side of the mega fuse and follows the right parking brake cable forward to the aft end of the transmission tunnel.
It crosses over to the left side of the tunnel and then up the left side past the shifter and then cuts back to the right at the forward end of the tunnel.
It travels down the diagonal tunnel support member and then attaches to the starter. I’ll secure this with adel clamps when I have run all the wires through the transmission tunnel.
I also installed a 4 AWG cable from the alternator to the starter. This is covered in black expandable sleeving and black heat shrink tubing in keeping with the color theme of the engine bay.
