240z engine bay wiring help

[polybius11]

I have a 1972 240z, and the guy I bought it from got a viper security system and a beefy sound system wired in (very poorly might I add). I need to rewire a lot of the engine bay and the wiring diagrams available are not helping, a lot of wires are spliced and replaced that don't match up or are just taped off and lead nowhere. If anybody has a diagram of all the 10 pin connectors that are located underneath the passenger side of the dashboard it would help a lot, or if anybody has any self made diagrams that are at all related to engine bay wiring please post them, anything might help me out.

Are you SURE you have a 72? The 10 pin connectors are laid out in the 73 FSM. What is the build date on the door plate? What is the VIN?

For completeness, this is what is in the 72 FSM.

These are the connectors I'm talking about, I'll check the VIN when I get home but it is registered as a 72

I would not be surprised if the door plate said 9/72 or later. I'm also wondering if you have the 5MPH front bumper from a 73. 

Those connectors are definitely what I've seen in 73s.

If it is a 72 or 73 I might have a good harness.

I have a really. Nice 73 harness with the same connectors

Alright so after a lot of looking around i found some diagrams someone else drew up, the wire colors match up for the most part. I'm gonna try to wire it up based on these, I'll update later this weekend whether it worked or not
