Picked these up off ebay... **** Wireless Turn Signal mirrors

With the work I do using my 98 Cherokee as a Pilot Car (escorting wide loads) letting the traffic behind me know what I need to do is of utmost importance as far as sudden lane changes go. This unit has turn signals built into stick on spot mirrors. The mirrors themselves each have 3 AAA batteries. The wireless module needs to be hooked up to 12 V.

The recommended set up is under the dash.
12V igniton/acc wire red
ground black
brown to right turn
orange to left turn

Does anyone know the wire colors of the 98 Cherokee steering column
as I would like to splice into the turn signals wires at the column.
