Most places ASK for the VIN to "ensure" it fits, but don't require it. You just have to pay return shipping if you order something without the VIN to verify, and it ends up not fitting.

Not in drive... I am almost 100% certain (and I'm too lazy to go outside and verify) that the lights will only come on in park and reverse (and possibly neutral).

Also, two more questions... Has anyone determined if the 2015.5 has the BCM programing or not? Does anyone have a blue switch for sale?

My eyes are hurting from reading 27 pages... I have a 2015.5 3500 HC Dmax. I have read about the latching relay, and such. I currently have the sports bar, and want to add lights to it (though I'll likely be using aftermarket lights, as the ones GM sells they are very proud of). My question is, has the "kit" been produced for the pre-2016 models yet, or do I need to build it out? Also, if I do need to build it out, is there a more detailed wiring diagram for using the latching relay module? TIA
