Single wire conversion

I see no real reason for a one-wire especially with a trunk mount battery, and in some cases it makes NHRA mandated disconnect more difficult. IF YOU do use a "one wire" and you race, and therefore need a disconnect please research how to do this properly.

You need MUCH larger/ oversized charge wire because the "sense" IS the charge wire, therefore voltage drop is much more of an issue.

If you use a disconnect, buy a good heavy FOUR terminal switch so you can "break" the ignition circuit/ relay.

If you are using an aftermarket wiring harness, great. If you are using the stock harness/ bulkhead connector, make certain you upgrade /inspect/ repair the bulkhead connector and ammeter circuit, or do a bypass
