Our Big 3 wire upgrade kit is a must upgrade when purchasing your new Pure Power Sling Shot high output alternator. It is important to understand that when upgrading from a stock alternator to a high output alternator your factory wiring harness becomes less efficient because it was not designed to handle 250 amps of current flow. By simply adding the Pure Power Big 3 wire kit in combination with your factory wire harness will allow your new high output alternator to produce its maximum amperage upon demands.
