Yoiur truck doesn't have an external flasher. The body computer handles that. You need to install resistors in order to not get warnings when you start the truck. I installed Sylvania bulbs on my 2017, they are kind of weird looking but they work by directing the light to the sides instead of straight out, this way you get better dispersion of the light. Thay are very bright. Another way is to change the programming in the truck so it ignores the lack of regulare bulbs. First responser equipped trucks have that from the factory, but an upfitter can do that programming. Most dealers do not even know about this setting and I havve a Tech 3 to access the computers but the new ones have to be called in to a central GM rep that must give you a passcode to enter in the computer to turn that feature.
I use Waze to tell me the posted speed and the curreent speed... but I'm going to order the Hypertech because has a Kalifornia approved sticker.. but i have to buy the one without a tuner...
problem is if you live in the great state of Kalifornia you can't get one delivered here and the new cars will tell the computer at time of smog check that a tuner had been installed and removed.... talking about Big Brother
It's much easier to go from the inside driver side fuse box. Go to gm upfitters. They let you download the electrical diagrams that show where you can grab power for auxiliary lamps. The third brake light circuit will not accept any other loads. Plus the harness only has power when the light goes on. I'm giving you a generic answer, if you let me know what kind of light you want to hook up I can give you more options.
Sorry for the long post.... but I felt some things have to be said about the sad state of affairs at GM with their light duty trucks.. 1500-2500 On the soap box There is no better time to get rid of it. My 2017 that I owe 20,000 on it, is worth 35,000 plus. Of course there is no way to replace it in this market. But if you are willing to buy a beater. youll have money for a down payment on a new on next half of 2022. I've always leased my truck because I'm self employed and could write it off. Now I'm semi retired and the business can not afford the leased truck. So I bought the one I have now. I regret it because although I love chevy trucks, they are becoming total pieces of ******, specially the ones we get in the West Coast from Silao Mexico. horrible quality control. luckily I know my way around cars/trucks/computers/etc... so I'm not too scared.. So my recomendation is DO NOT buy another one, lease it if you drive less than 15000 miles a year. GM has been on rush to catch up to Ram trucks and Ford trucks. so instead of spending 3-4 years on testing and getting all the bugs out, from 2016 on they started selling trucks that were only road tested for 2 or so years. So we customers become beta testers for GM. Now as the newer trucks come out since the architecture has been the same for the last four or so years.. then the bugs have been worked out pretty much... The Achilles heel are the transmissions... Would you guys believe that a partership between Ford and Chevrolet worked on the new multispeed transmissions for three or so years.. Multi speed = 6 spd to 12 spd Ford came out with them 5 years ago, even the mustang had an 8 speed and I think now a 10 speed. Meanwhile the same F****g transmissions GM can't get them to survive 100,000 miles on the 1500's trucks. Most of the thing's I've mentioned are available on Google or on SAE.org (Society of Automotive Engineers. OK I'm off the soap box
What kind of aftermarket bumper you installed? You can drill it to mount the sensors. I can give you the measurements of the hole drill. Im on a business trip and I can reply to you with the size. Send me a private message if you want. Another question. What year and model Silverado do you have? I'm looking for a good undented bumper.. thanks
