SC 300 and 400 wiring diagrams
 

These diagrams are from my old installation program I used when I owned car audio stores, but since they cover a wide variety of things such as tach wires and other things of interest they work as a general reference of wiring for the SC 300's and 400's.

There were indeed subtle changes on each revision that you should pay attention to.

This took a good while to photo and organize so don't say I never do anything for ya :D.
