What is this?
I am going through the dash and trying to fix all what previous owners have botched. I cam across this and not sure what it is. My K10 doesn't have this so I am thinking it has something to do with this K30 being diesel. I found it under the left hand side dash under the headlight switch. It was just laying on the backside of the lower dash not hooked up.

Re: What is this?
I am about ready to tear the cluster out here in a day or two so I will see what is there. Everything seems to work except the oil pressure gauge but that is an easy fix. The "water in fuel" light stays on all the time. I suppose that is why the PO pulled the bulb out. That might explain why I didn't see it on my K10 since I have not had the cluster out of it. Anyway I will check that out. Thanks.

Re: What is this?
Bringing this back to the top. It does screw into the back of the speedo but what is it. The part number is 25007327 but I can't find it when I google the number.

Re: What is this?

Re: What is this?
It's an optical vehicle speed sensor that reads the vehicle speed via the speedo.
http://www.rockauto.com/catalog/more...=40855&cc=2796 It's used by the cruise control http://www.justanswer.com/chevy/6mti...chevrolet.html

Re: What is this?
Is that the one that lets you know you are going over the speed you set?
