Hi Walter,

For the Deka Battery Isolator # DW08770 you can go with 8 gauge wire. Deka actually makes an installation kit with this wire, the Deka Battery Isolator Installation Kit for Standard Alternators # DW08769.

Hey Walter, how did things go with the 8 gauge wire and the Deka isolator setup? Your update could make it easier for the next person wiring their auxiliary battery.
