As listed above but with correction. Alt to battery is same as 6 ga to power block. A 10 ga fusible link is spliced in nearest the battery for the alt to battery. The 2 ga. was actually from battery to starter. Sorry about that. That was for '96. I think '99's went to a 4ga. from batt to power block. Can double check others if needed but I think other where similar in size. Having to convert from metric to AWG size on the diagrams. My subscriptions are far '95,'96 and '99 so I get coverage for '92 to maybe 2000 carryovers but sometimes it takes more research to find out exactly what wire was redesigned in a '98 for example. '98's should be same as say '96 but of course a new auto 4x4x was introduced that changed diagrams. So I go to the '99 charts for that. Make sense.

Any 2ga. high end wire would be good for upgrade on batt alt or power block with everything else in system stock.

Personally want to go high amp alt with some extra batteries but run inline fuses with a power post where POS+ from power block, alt and batt meet up. Have not been fan of the double stack battery terminals with no fuse protection for battery to power block.
