Yes we have a few things to fix on the 2003 nbs GMC Sierra Stepside. The first thing we tackle is replacing the relay a took out for the dually build. While replacing the relay I wanted to do the 6 on mod or the all on mod for the 2003-2006 and 2007 Silverado Sierra Tahoe Yukon and Escalade. This allows you to use dims, brights and fog lights all at the same time. It is a simple upgrade that just requires removing a few relays, putting in the small plate and replacing the relays. It is a even bigger upgrade if you have led bulbs. It no longer kicks off the fog lights when you turn on the brights. Next we fix a common issue on gm trucks in these years. The Oil pressure sending unit. When I bought this truck the oil pressure was not reading correctly. This oil pressure switch or oil pressure sensor can be installed on the truck without removing the intake. You will however get some scratches on your arms. After replacing this the oil pressure is now reading correctly and back working. Last I was not a huge fan of the bullet antenna that the truck had. Instead of buying a short antenna, I decided to have Kam help me cut down a stock antenna. You can make your own and it works as well as the options you can buy. The short antenna will cut down some of the reception but I can still pick up radio stations from about 40 miles away. We have a few more fixes to do on this truck to get it up to my level. Follow along as we have more NBS Truck content on all the projects in the shop. Hit the Comments and let me know what you think…….

Would the 6on mod work for 1999 gmc sierras?
I have an aftermarket short antenna on my Ford Explorer but, I never use the radio…my wife got me into Spotify.
Great mods on that truck it looks sick as is , big inspiration as well I got my 2006 crew cab because the build u did
I ORDERED THE GM ALL LIGHTS MOD FROM FLEECE ALSO ITS GREAT
Such a good buy! That truck is clean! Hope you’re recovering good from all the scratches! I had to do it twice on my 05 cateye Silverado and my 2012 Silverado .
Nice work. Love the red truck❤ If you ever decide to sell it , hit me up.
That antenna mod I figured out in 2006. I’ve never seen anyone else do it before. Great minds think alike.
I have a ree 99 silverado that im doing a v6- v8 swap now. I absolutely love these nbs trucks and my obs trucks are my all time favorites. Still have my nnbs dually as my daily till my 99 is done and will be my new daily with a choppy cam!
Where did you get the tool for the antenna??
Nice work, the home made shorty antenna is one of the first mods I do to my trucks too.
It's not a bad Idea to pull the screen out of the block where the sensor screws in. Mine started acting up because of the screen after about a month after replacing the sensor.
6 on mod is so good! Red next to white truck looks very good
I changed my oil sending unit n it is hard hard hard on the right hand , not a job a guy wants to do very often .
Kam’s the best!
