I have a 97 Nissan XE 4x4 PU.

I am looking for the wire(s?) that run from the horn pad to the horn
relay. There is nothing wrong with the horn or relay. I want to have the
horn beep when I lock or unlock the doors on my aftermarket keyless entry.
I do have an unused AUX negative volt wire from the keyless entry
controller. I thought that might work but it didn't. The parking lights
do flash when I unlock/lock the doors. I suppose that I could tap into
the Keyless controller's parking light wire and run a wire from there to
the trucks horn button wire, if I knew where it was. I have taken some
pics of the steering column with the housing removed. There are 7
connectors on the column with many wires. Pics from various angles are
here:

If you know which one it is, I would appreciate it.
I'm just guessing here, so if you know that it would be wrong to do, I
would appreciate that info too.
