    Hey guys,
    I have a federal signal streethawk lightbar and was wondering how the brakes and turn signals work in. Do I hook them up to one of the switches and it will operate through the relay, or do I splice them into the main harness somewhere? :help: Any help would be greatly apreciated.

    Yea, I just bought this CJ7 so I am not sure if it has a trailer wiring harness, but I'll just hook it up to the rear lights if so. Thanks for the help!

    The federal Signal Street hawks never came with S/T/T lights, those two lights under the rotators are alternating flashers or work lights, depending on how they were wired up in the bar. :rolleyes:

    Normally the Street Hawk came with four rotators, two rear halogen flashers, two alley lights(one on each side) a pair of front takedown/work lights(front). With just the rotators and flashers you will be pulling close to 25 amps. Make sure you have a HO Alt and a big battery. I would use 8ga wire to supply the main switch box with a 40 amp fuse. Use the maxi's. Brookings Industries makes great switch boxes and are sold at a good price. http://http://www.lshlights.com/AMAZING. Halogen lightbars with rotators are power robbing.
