Good Info!
 

The whelen info is good stuff! seems a straight forward install. Thanks for posting that. How many other SSP's were equiped with these?
BTW they are the 3 wire type. I have not had the chance to take the trunk or interior apart to see if there is a power box.
Thanks
Rob

No telling how many had these....they weren't super popular until most of these cars were coming out of service.

My department retro-fitted them to one of the Mustang traffic cars we had that was still on the road...probably in 1999 or so.
