Description

If you are upgrading your Samurai or Toyota Pickup headlights to high output H4 bu or H4 LED you will need a conversion harness built just for this purpose.

High output bu require a relay style harness to deliver the necessary power.  Your factory wiring can not make the most of aftermarket bu.  Even worse, LED headlights are usually not designed to work at all with the ground switching system found on these models.  Most LED headlights will only function on one side or be stuck on High or Low.  

These are not the same harnesses that others are selling as Universal kits.  These are specifically designed to fix the problems in Samurai and Toyota Pickup headlight upgrades.  

This H4 Relay Harness will plug into the factory wiring harness on Suzuki Samurai and 79-85 Toyota Pickup and 4Runner.  These are able to provide the power needed for headlights from IPF, Hella, and others.  Simply hook up power and 2 grounds and then connect your old headlight plugs into this harness.

Features Fused and Relay protection for headlight harness.

NOTE:  Make sure your LED Headlights are intended for H4 applications.  This harness will not work with 4656 or similar bulb standards without some modification.
