"HORN HELP"

[John Betsch - "SADIE"]

When I acquired my 230SL (over thirty years ago) It had only once horn.  I am finally correcting that situation.  Unfortunately I have no idea how the second horn should be wired in.  I only see one wire going to the existing horn (passenger side)

Can anyone help with info on how the two horns are wired? Parallel, in Series?  Connected to what etc?  I couldn't find much in the Tech Manual

Any advice to a novice is appreciated

John,

This very recent thread has all the information you should need, and perhaps more!

Much thanks to our electrical guru, Eng. L. Peterssen, for sharing his expertise!

I can see where the wiring for a passenger side horn is routed (appears to be routed through the air filter housing.)

I cannot find any wiring on the drivers side.  I assume that sometime in my pagoda's lifetime it was cut for some reason.  I am guessing that wire from the horn would be routed up into the ?engine compartment, and travel along the driver side firewall?  Anyone have any ideas or pictures?

The passenger side wiring should come from the driver side connection. The wiring harness is routed along the left side to the left horn.  From there,  two wires (same colors) take off along the front to the right horn.
