Wakespeed WS500 Advanced Alternator Regulator

from $599.95

**NOTE - Temperature Sensor Sold Separately

The Wakespeed WS500 27-foot wiring harness is purpose-built for van and RV installations where the WS500 Advanced Alternator Regulator is mounted away from the engine compartment—typically inside the vehicle’s electrical control area, near lithium batteries or power management systems.

This harness is designed specifically for P-type alternators, which are commonly used in modern vans like Mercedes Sprinter, Ford Transit, and RAM Promaster platforms. The 27-foot length allows for complete front-to-back routing through factory channels, firewall passthroughs, or underbody conduits.

  • 26-foot overall length – Ideal for camper van and overland builds
  • Supports P-type alternator configurations – Includes field, ignition sense, CANbus, and communication wiring

Testimonials

Absolutely stunning, from the shipping and delivery to the impeccable packaging and identification of the parts. I installed in about ten minutes with the video which was linked to my phone via the QR code included in the kit.. Can't say enough about the fit and finish of this kit. Very reasonable price too when you consider all of the extras.

Hood Strut Kit Review

The mounting system works great. I originally installed my MaxxAir fan with sheet metal screws but opted to replace it with with this and glad I did.
