New large cap HEI distributor connector. There are two types of large cap HEI distributors, and each use a similar, but slightly different connector. The stock TPI distributors from 85-86 used this connector. The 84 and older distributors used a different connector, part number WIR-330. This connector will work only with large cap distributors with a screw down cap. If your large cap distributor has a latch-down cap, this is not the correct connector for you. The difference between the two is the orientation of the slots in the prongs.
Assembled with new connectors, terminals, and seals from Packard, and TXL grade wiring. These are the same products used by GM on factory harnesses, and the leads are GM color coded. The 6 inch leads for this connector are are black/red, tan/black, purple/white, and white.
