I'm going through my wiring harness with a fine tooth comb and I have a couple of questions.
In this picture: I. What are these four connectors for? I think they are for the center console. Is that right? II. Is this green wire for the parking brake switch? III. Are the brown wires for the door switches and the black for the internal light.  What is this for? I believe it mounts somewhere under one of the seats and is used to connect the harness wires to the door switches. Where does it mount? Which accessories are connected through it?  The plastic connector holder on my turn signal switch is very brittle. I don't suppose there are any aftermarket replacements?  Lastly, where can I purchase all new grommets for the wiring harness? Thanks. George |

I've traversed the entire harness and am now deep into the dash components. It looks like at some time the wire from the light switch to the parking light indicator completely melted. The sheathing is stuck to multiple wires and there are brown marks everywhere.
Any idea what could have caused that melt down? I'm wondering if the wire rubbed through the light holder and grounded to the gauge. If so, I'm thinking of replacing all of the little bulb holders with ones that have an attached male flat connector. (Instead of the kind where the wire goes through the end of the bulb holder.) Editors note: I was reading the 1973 fuse box wiring diagram and found this gem. "High Beam indicator (Tach) and parking light indicator (Speedo) are unfused…" So that explains that.
