Knock Sensor Wiring Harness For Toyota 4Runner, MR2, Lexus LS400 – OEM 89615-50010, C-HORSE
About this item
This is a direct-fit knock sensor harness for select Toyota and Lexus models—think 4Runner, MR2, LS400, and even Tacoma.
OEM part number 89615-50010 is the magic number here.
If your engine’s throwing knock sensor codes or you’re replacing the sensor itself, don’t reuse that brittle 20-year-old wiring.
This harness from C-HORSE is brand new and ready to plug in.
It includes everything you need: the correct length, proper terminals, and heat-resistant sheathing.
No splicing, no guessing.
Just unclip the old one, route this in, and clear those codes.
Matches interchange numbers like SU4040, KS159, and 82219-07010.
Solid fix for a common issue.
