Hitting this topic again as I've been out for a long time due to Covid. (All through Christmas, New Year, and beyond). Is connection 524 and 307 a steady DC signal as long as the turn signal switch is engaged? Or is it pulsing with the turn lights?

Thanks for the info. I'm finding that the 2019 Silverado to be somewhat an enigma. None of the auto part stores seem to have information on the electrical system, but I'm also finding that good mechanical data is scarce. What I was told by the NAPA guy was that 2019 was a "Change Year", and some components were made from stock of 2017 and before, while other stock was from the new 2020 and later vehicle. First time I've heard of something like that. EDIT: I received an e-mail to check this URL... https://www.gmupfitter.com/wp-content/uploads/2021/05/19_Silverado_1500_Body_Builder_2019.pdf Page 34 may be the page I need, and tapping 524--WH and 307--YE/BN may be what I need. I only need 34mA of +12v to drive the flood control module for lights.

I have a 2019 Silverado 1500-LD double cab. I've been trying to find a good wiring diagram for the vehicle, but there is nothing in Haynes, or on the web that I found. Dealer is of no help unless I want to buy the complete shop set which includes all mechanicals and engine types. The mission: 1). Install cab roof lights. Another message gave me basic info, but no specific terminal numbers. 2). I would like to locate the wires and tap the signal off the turn signal switch to a relay, turning on floods on the side of the grill guard. This is to have better illumination in the direction of turns on logging roads. 3). I would also like to put radios in my truck which we use for comms on the highway and sites. I'm looking for a convenient way to tap for the accessory signal for a relay, so when ignition is off, so are all the radios. It's my impression that there were changes in the 2018 and before, and 2020 and later which do not apply to the 2019. Any help in finding a manual showing accurate drawings, (downloadable or manual purchase), for the 2019 1500-LD would be appreciated.

If you're not interested in the prices, would not one of the Vin Decoder sites work for an inventory of the vehicle?

Old thread, but I'm just now coming in on this. Am I correct that the cab roof light harness plugs into a connection in the truck, or must you "tap" existing wiring for the B+ which feeds the roof array? I'm contemplating putting roof lights on a 2019 Silverado 1500 LD double cab. Haynes and other sources have not been too helpful in identifying electrical.
