03+ Crown Vic horn/siren jumper

On p. 3-8 of the 2004 Ford Crown Victoria modifier's guide, there is a picture of an optional (VSO) jumper harness that appears to simplify the connection of the horn ring to a siren (Item #3 in picture). Anyone know if this harness is a Ford item which can be ordered (part # would be especially helpful)?

Yes & no, it used to be able to be ordered, Ford supposedly discontinued it, I have a box of them, I can get a part # on Monday.

This completely slipped my mind, your part # is.....

5W7Z-14A411-AB, they call it a "wiring assembly".

Good luck

Thanks, I have one of these, but it is for 2005 and up only. 2003 & -04 have a different steering column and wiring connectors. Any one else? Need one, thanks.

Hi Y'all: From 2004 thru 2010, Crown Vics that did not have the police package wiring on the passenger side below the glovebox: I ran a green and violet twisted pair from the siren thru the firewall to the Ford relay panel in the engine compartment. Unbolt the relay panel and flip it over, cut and splice in the grn and vio wires to the bottom of the horn relay. Wallah, you now have siren horn ring. PTL!
