Custom BIG 3 Wire Kit 1/0 AWG
(Required for all High Output alternators)

Our Big 3 wire upgrade kits are a must upgrade when purchasing your new Pure Power 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 to 400 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 the vehicle demands.

What's Included:
4 ft of 1/0 Gauge Premium SGT Positive Cable
3 ft of 1/0 Gauge Premium SGT Negative Cable
30 in. of 1/0 Gauge Premium SGT Negative Cable
6 Pcs. 5/16 Ring Terminal
Machine crimped ends with weather resistant adhesive heat shrink tubing

    This unit comes equipped with a smaller alternator pulley, and we recommend using a ½ inch shorter drive belt for proper belt tension. For information and help to identify your current belt size and locating the ½ inch shorter belt size needed, refer to our Technical Notes, Reducing Your Vehicle's Belt Size | TAE (tucsonalternator.com). Our smaller drive pulley is not recommended for sustained use above 5,500 RPM engine speeds.
