I'm probably not going to say this right, but by definition, a reluctor wheel is a cogged wheel with metal vanes. As a shaft rotates, the reluctor wheel vanes pass between a magnet and a coil, a magnetic field is interrupted and voltage is produced....basically allowing for monitoring of how fast a shaft is rotating. They are used for crankshaft sensors, camshaft sensors, etc. In some cars, they are also used in differentials to send information to monitor traction and slippage for traction control , ABS systems to monitor individual wheel lockup, that kind of stuff. I'm sure someone will jump in with a more accurate description......

They called it, '06. From what I've read though, not all '06 had the 58x wheel, the earlier ones had 24x still. The color of the harness will help determine, as well as the cam position sensor style. The older 24x had a 1x cam position sensor (the cam gear had 1 raised area), the 58x had a 4x cam position sensor (4 raised areas on the gear). The GTO retained the 24x throughout the model year, where as the Vette changed over.

If you're talking about the cam reluctor, then it changed with the 07 model as part of the switch from a 3 bolt cam gear to a single center bolt. Gm makes a 07 reluctor with the 3 bolt 06 mounting to match older cams.

If this is what you're talking about. Ask Dave. My car got held up at Cartek an extra day because of the change over. An '06 gear came in instead of an '07. If you're talking about something else then just ignore my post.

it is my understanding that the '05 uses the 24x gear while the '06 and up uses the 58x gear.
"2005 Model Year, has 24X reluctor wheel"
"Starting with the 2006 model year, the LS2 now comes with a 58X reluctor wheel and new camshaft sensing, and is not compatible with pre-06 ECMs."

I *believe* it's a gray harness for 58x, black for 24x.
I checked it again, and according to Speartech (on another forum, sponsor), that's correct.
The '06 was definately the change over, and I've never personally seen 24x in the vette on the '06+, but there are definately rumors that they exist. That said, the easiest way is to check the cam sprocket for raised sections, 4x indicates 58x reluctor as they come hand in hand.
