Help installing new '69 forward lamp assy harness

After the good success (thanks Donny!) with my '69 engine bay harness thread, I need to tackle the other harness - the forward lamp assembly harness.

Here's what I have:
  1. Single-wire plug (tan)
  2. Single-wire plug (dk. green)
  3. Two-wire light bulb socket (black, dk. brown)
  4. Four-wire head lamp plug (2x tan, lt. green, black)
  5. Two-wire head lamp plug (lt. green, black) and a black ring terminal too
  6. Three-wire plug with only two terminals (dk. brown, lt. blue)
  7. One-wire (thick) 90-degree ring terminal (red)
  8. One-wire plug (pink w/ stripe)
  9. One-wire plug (black)
  10. One-wire ring terminal (black)
  11. Four-wire (large) plug (dk. purple, orange, white, blue)
  12. Two-wire socket half-way down the harness with no slack at all (?!)
  13. Two-wire plug (white, blue)
  14. One-wire (thick) ring terminal with a boot (red)
  15. One-wire (thick) small ring terminal but no boot (red)
  16. Four-wire head lamp plug (tan, 2x lt green, blk)...
  17. ...chained to a three-wire lamp socket (2x blk + ring terminal, lt. green)
  18. Two-wire lamp socket (dk. purple, black + ring terminal)
The plugs & sockets for the actual lamps are easy, so no issue there. And I'm pretty sure the thick red wire with a boot is for the alternator. But I could use some help deciphering the other ones..! Please

Re: Help installing new '69 forward lamp assy harness

Sounds like you are talking about the engine harness. The forward harness does your lights and regulator and connects to your fuse bulk head.

I started with Nothing and still have All of Nothing!

Re: Help installing new '69 forward lamp assy harness

I've made some progress:
  1. Single-wire plug (tan) brake failure warning switch
  2. Single-wire plug (dk. green) temperature warning light
  3. Two-wire light bulb socket (black, dk. brown) driver side lamp
  4. Four-wire head lamp plug (2x tan, lt. green, black) driver low beam
  5. Two-wire head lamp plug (lt. green, black) and a black ring terminal too driver high beam
  6. Three-wire plug with only two terminals (dk. brown, lt. blue) parking light?
  7. One-wire (thick) 90-degree ring terminal (red) ???
  8. One-wire plug (violet with black tracer) horn relay?
  9. One-wire plug (black) ???
  10. One-wire ring terminal w/ fusible link (black) horn relay?
  11. Four-wire (large) plug (dk. purple, orange, white, blue) voltage regulator
  12. Two-wire socket half-way down the harness with no slack at all (?!) parking light?
  13. Two-wire plug (white, blue) alternator module
  14. One-wire (thick) ring terminal with a boot (red) alternator post
  15. One-wire (thick) small ring terminal but no boot (red) distribution block
  16. Four-wire head lamp plug (tan, 2x lt green, blk)... passenger low beam
  17. ...chained to a three-wire lamp socket (2x blk + ring terminal, lt. green) passenger high beam
  18. Two-wire lamp socket (dk. purple, black + ring terminal) passenger side lamp
I have a kit from M&H Electrical that converts the externally-regulated harness to an internally-regulated (10Si alternator) harness, so that's fine.

According to the color wiring diagram posted in this thread, I need to figure out how to wire in the horn relay. It has:
  • One-wire plug (black) horn
  • Red wire (power for the relay?)
  • Black wire (GND for the relay?)
  • Black wire with circuit breaker/fusible link (power top? but I don't have a convertible)
  • Violet wire with black tracer (key buzzer?)
Suggestions welcome!
