Overview

Replaces OEM 0439561. This is a Rectifier Regulator and Gasket. Due to a design change, the PURPLE DRAIN WIRE is NO LONGER NECESSARY. This drain wire may be contained within your existing wring harness in either a multiple pin connector or as an individual wire connection. If the purple wire is contained within a multiple connection, no further action is necessary. If the purple wire is an individual wire connection, make sure the existing harness wire is secured away from any moving components.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
