Changing Whelen Flash Patterns
We are about to take delivery of a new engine with a Whelen Warning light "package". I have read the instructions on line about changing flash patterns, but it seems a little more complicated for a novice/amateur like myself (unplug this wire...take this wire and apply 12 volts to it...isolate that wire...etc...).
Does anyone have a way to explain this to me in more simple terms? Is it really as complicated as my brain is comprehending it to be? Our 2005 Tanker has a Code 3 light bar, and changing that flash pattern was as simple as pressing a flat-head screw driver to to connector/connection thingies.
Obviously, if I can't figure out how to do it and not blow up the truck...I just won't do it. But surely it can't be that complicated.
