Thanks for the quick reply.

the wire will run from the front bumper to the dashboard (driver side), if it's long enough.
There's a nice little story why I need to do that.
The Davis County Sheriff Department uses a Saturn Sky.

A good friend came up to me and asked if he could install undercover lights in my car (temporarily last year).
Here is a little vid.

Everyone asked me to start the siren, but I didn't have one.
So this year my friend asked me again if we could install the lights and in addition a siren (temporarily) for the convention.
The wire is for turning on the siren and switching the sounds yelp, wail etc.
Please don't laugh the Germans love U.S. Police cars
