Awesome!

Took a little longer just making sure which modal to remove and connect into. Have a ‘25 Sierra 2500 with I believe 7 BCM moduals and 5 LCM ones to the right of it up under the left side. The bottle panel pulls right off. Need to use a curved pick hook to pull down on the release tab on the left (inside) of the 2nd from rear purple connector after lifting up on the white retention tab on the right (outside) then slips right out with little effort. Plug in splicer modul and zip tied up under dash. Choose to run the long black wire button switch up under kick panel, up around the left inside area between dash/ steering wheel and routed on top of panel where light knobs are at. I ended up liking flash pattern one and moved the (4th or 5th?) dip switch to slow flash which gave a nice wig-wag (back & forth) pattern. I love it flashes all the front and rear lights on the side mirrors which are very attention getting. Been telling everyone about this product and showing it off!
