Thanks Mike! I've decided to go with 2/0 since I'm running a 180 amp Nation's alternator. Balancing the charge system seems a good way to go. Mike

I've been reading this thread with great interest the past day or so. I'm about to replace and upgrade my battery cables next week, and this seemed like a good time to do the WT Mod. A couple of points I'm unclear on: 1. Cleaning up the grounds on the passenger side running up to the computer modules on the firewall, and... 2. Size of the negative crossover cable added between the batteries. Several different sizes have been mentioned in different posts, i.e. 4AWG, 4/0, and 2/0. What's optimum? Go as big as I can? My new positive crossover cable will be 2/0. thanks! Mike
