Has anyone installed the Whelen UHF 2150A wig-wag flasher in an '02 TrailBlazer? From what I've read it's not so easy.. any feedback is appreciated...thanks!

Ive used a regular sound off without a problem.. It is standard positive switching. I just finished one for the US marshalls..

Okay, excellent. Someone had told me that it was positive switched until it got to the relay board and then it was negative switching beyond that point. I just wanted to make sure that it wouldn't backfeed into the computer system in the truck and cause any problems. If so, I may just put some diodes in to prevent that. Thanks for your help
