Can anybody explain the codes discribed in the workshop manual; the ones written above each wire in the wiring diagrams. I do know the color codes, they're explained in the legend in the manual, but what about the other codes...
For example the wire to one side of the ballast resistor: J2A-16DBL* The DBL* means dark blue with a tracer but what does the other codes mean? Also in the wiring diagram the wire goes from the ballast resistor to a "1 in a rectangle symbol" What's that? (this is an example from the 72 wiring/all engines)
Just want to know cause I'm gonna rewire a couple of wires.
