If you’re building an LS engine with a Holley EFI system and you’re dealing with that annoying 58x to 24x reluctor wheel mismatch, this little harness is exactly what you need.
It’s a brand new Crankshaft Position Sensor adapter harness from Holley, made specifically to convert that 58x signal so your Holley ECU can read it as a 24x – no more headaches, no more custom wiring nightmares.
This thing is plug-and-play, straight out of the box, and it’s made in the USA, so you know the quality is top notch.

No universal fitment – it’s designed specifically for Holley EFI setups with LS engines.

It’s a small part but it makes a huge difference.
