I have a painless wiring kit, seems to be very thorough, but I have no idea what this component is, and I can't find it in either the painless schematic or the chiltons schematic. What is the component below the voltage regulator? Thanks.

 

I think that is the horn relay and key warning buzzer. The drawing below is from the Assembly Manual.

 

Awesome, thanks! That makes sense because the painless harness said it repositioned the relay to the fusebox. Looks like I'll need to look for an assembly manual. That would be useful on every project.
