Laurel Starting Issue

[c33matt]

As a continuation of my last post, I’ve narrowed down the problem to the starter signal wire. When testing at the connector I’m only getting 2.5 volts. A test at the fuse shows 12, so the ignition switch itself is good. Obviously there is a problem somewhere in the wire but as it joins a large loom I’m having trouble finding where it comes into the cabin. Does anyone have a wiring diagram for the starting circuit or know where the signal wire can be traced back to?
