Wigwag light flash module

[LanceD]

I was looking for the wig wag light module that is installed to activate the flashing alternating lights. The upfitter guide says it's installed on the radiator support on the passenger side but I can't find it. I applied 12v to the green wire in the harness to activate it but nothing happened. Is there anywhere else it would be or does someone have any pics of one? Maybe with a part number? I'll be looking to add one if mine was removed.

Yeah it works great on my 2011 PPV but can't find it on the 18 model. I tried applying 12v to that wire and looked on the radiator support but I didn't even see any connectors that it would tap into. Unless it's on the front side under the plastic cover?

do you know for a fact that the vehicle is equipped with the module. check your seo codes.

I scanned the QR code to get the codes but it doesn't show them all. How do I find the rest? Theres no label in the glove box like my older one.

I found more on a VIN decoder website but it doesn't show it. Maybe it didn't get one.

Look straight down across the headlight plastic covers through the radiator support.

Mine didn't have the factory one, the upfitters installed one along with everything else. I think there is a plug in module that will put the BCM into "light test" mode, which will turn your Tahoe into something out of close encounters, but I don't have any experience with those.

vin decoder is not going to show a wigwag, that's 3rd party equipment which is often pulled out when sold as a civilian vehicle, if you have no high beam function that would likely be one way to tell it was cut out
