    Greetings all-

    Just thought I'd pass this along, since I couldn't find something similar on fabo (it probably exists, but...).

    Regarding the bulkhead diagrams available for my Barracuda, I found that the manual, as well as my 11X17 laminated, colored diagram aren't exactly laid out in a manner that easily provides a "view" frame of reference. Before I created the diagram, I had to imagine myself as a tiny man, straddling my firewall between the connectors, and looking toward the headlights, and then turning and looking toward the steering wheel... but only after rotating the original diagrams downward at the outer extents (see the "original" pic), so they rotated down in front and back of me like a set of old, rigid garage doors!

    So I created a supplemental bulkhead diagram (google doc at left, PDF) that shows the bulkhead from two graspable views... standing at the headlights looking at the bulkhead, and looking at the bulkhead while laying in the car and looking toward the headlights. This is particularly useful when pretzeled under the dash and you need to double and triple check which bulkhead wire is which!

    I hope I got everything correct!

      It often helps to do your own. I've done the same with the connectors. Sometimes on computer, often on paper while looking at the real thing.

      I don't know if you had seen the layered pdfs 1969383S has made and shared.
      1969 Plymouth Barracuda wiring diagram (not mine)

      They're based off the factory diagrams and then edited as he finds info.
      I haven't used the '69 version except to occassional compare with '68 and '67

      That's a great effort, if you have the skill you could label them with the circuit/ wire number and wire color.

      I'm used to this, as I've screwed with electronics in some way since I was in Jr. High about 62-63. Back then we were screwing with tubes, and other connectors so you always have to be aware of what side of what half of the connector you are "on"

      Generally, the rear of the female connector half is diagrammed CW from some starting point, and so the rear of the male half is mirrored from that. And so you have to mentally transpose that if you are eyeballing the "pin" end of the respective connector half

      Yes, a while back I saw those layered PDFs, which are awesome... but at the time, if I remember correctly, they weren’t working on my Mac laptop.

      Just a passing thought for those less inclined to dig into the wiring.. I remember a time (not that long ago) when it was all a terrifying black box. My first ground-up motorcycle build helped me immensely (i designed and built the wiring system.. appropriately, a pretty simple one for a 1973 Yamaha RD350 two stroke cafe bike).. but when I bought my project car, I vividly remember thinking “how in the hale am I going to figure out what all these dangling gray (someone’s paint over spray) wires are for in this empty project Barracuda engine bay?”

      I’m no expert, and only have a basic understanding, and I have a lifetime of learning and understanding ahead of me, but really... it’s all very simple, if you start small, get some VERY basic tools, and understand the fundamentals first... and try to not let the rats nest intimidate you... you’ll be the better person for it!

      Wiring and rewiring to clean things up, has become one of the most satisfying and enjoyable aspects of working on my car. Especially routing and cutting any and all wires. It’s all so tedious, calculating, and surgical!

      Anyway.. most of what I learned was right here from you all... so thanks much! :thankyou:
