As my Dad always told me , I'm an expert at making things more difficult. My newest venture was to attempt to install a euro horn set on my '84 CD. Horns didn't work as I thought they sure, so I began the restoring process to put it all back.

Long and short of it is that I crossed the horn & turn signal pins in the plug. Now I can simply signal left to honk at someone. Did I mention that I thought it would be a simple fix and let a couple of weeks slip by before I tried to correct it.

Now I have no clue which pins (actually female plugs within the plug) are crossed. Does anyone have a diagram of this plug's pin location?

Thanks in advance for the wiring help, and laughing in private at my stupidity. And don't worry, I've laughed at my own mistake enough for a hundred of us on this forum!

Don`t feel bad, we have all done something similar.

The 123 FSM Vol 1 I have has several wiring diagrams, the newest one is for 300D/CD 123.130/150, 1981

I assume the 84 must be the same, or close?

Pin #5. two wires connect to this one. 1sw/ge rs both wires same color
pin #4 1,5 sw
pin #7 1sw/gn ws
pin #8 3 wires connect to this one. (1sw/gn) (0,5 sw/gn) (0,75 sw/gn)
pin #6 3 wires connect to this one. (1sw/ws) (0,5sw/ws) (0,75sw/ws)
pin #3 2,5ge
pin #2 2,5ws
pin #1 2,5ws/ge
pin #11 1,5sw/vi
pin #14 0,75sw/ge vi
pin #10 07,5sw/rs vi
pin #9 1,5sw/ge
pin #12 1,5sw/bl vi
pin #13 1,5sw/gn vi

Note: not is numerical order, that`s the way it is laid out in the schematic.
hope this helps

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works

Thanks guys! I had crossed the horn hot and left turn output. Now it works like a charm.

Next time I'll take a photo of the thing before I start changing things up!
