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:
