My OEM GMC headlights are not yellowed nor delaminating.
That said, I took a 1200 mile trip through Wyoming last week and that's a key upgrade I would like to do.
Got a bird strike also which broke the previously cracked bug deflector.
Heavy signage on open range 2 lane roads for Cattle, Pronghorns and Sage Grouse.
Went around the corner and there were the 2 pronghorns just waiting to run out on the road.
I did not harvest the Sage Grouse that caused the bird strike.
Lucky it just rolled up onto the windshield and didn't break it.
Any recommends appreciated, truck has 73k original miles and will be the last truck I buy.
I just used Sylvania LED lamps for my 06 Sierra. Using the factory housings and the Sylvania lamps gives me factory original look and bright white lights, able to be aimed. Really satisfied.
My housings were original and not good so I bought OEM from ebay. New housings and LED lamps were a game changer.

My CTS3 was doing something similar - would sporadically not turn on when truck started, would cut off sometimes, etc. Voltage was fine and I had autozone check their scanner for codes - they could read everything fine. Sent unit to Edge. They said they updated and replaced the screen. Got it back and it turned on a couple of times then nothing. So … I bought a new obd cord and it hasn’t missed a beat since - about 10 months ago. Might be worth a shot - cord was pretty cheap.
Edge sent a new cord with the new head unit. Didn’t make any difference, with my old head unit or the new one. Only after disconnecting the TCM, and later the 6-Gun, did things start working again. I completely unplugged the 6-Gun last night. I’ll have to reconnect the CTS and drive it a few days now.

Took the Camaro out today for a shakedown run before headed to a car show tomorrow 70 miles away. First time out of the garage this year. Smooth sailing the first 5 miles, then went WOT and she started to break up, backfired, and cut out completely. Quick diagnosis on the side of the road, no RPM signal, and found the terminal on the distributor power wire is bad. Got it running and back home fine. We’ll take the truck instead lol

pls post an outcome / what the outcome or fix. My cts3 has had few hiccups and I’d like to know your result.

I’ve been stealing time when I can to figure out this data communication issue. Unplugged the S205 splice connector to test each module individually. Nothing seemed to stand out as the problem, similar readings on each module circuit. Same with the Banks 6-Gun plugged in or disconnected. And with everything reconnected, my original CTS3 still had the same issue- no data when the 6-G connected, reading but with missing PIDs with the 6-G disconnected. I tried the New CTS3 again, with the 6-G disconnected, and it works fine. I removed the 6-Gun completely now.
The main Engine-to-Chassis harness connectors had some corrosion in them also. I dug around to find out what terminals are used and ordered a full set of replacements. Metripack GT-150 & GT-280 Sealed terminals. The smaller 32pin male connector was the worst and I replaced all pins in that connector. The other ones only got new terminals where it needed them. I bought way more than I needed 🤦‍♂️.

She fired right up after this and runs smooth as silk. New CTS3 reading fine also. I’ll get some drive time later this week.

Looks like FUN! Not.
I actually like this kind of work lol

Also did the hidden radio antenna mod last week. Turns out the cable was corroded out of the base so I had to replace that as well. The truck looks so much cleaner without the antenna sticking up

I made the bracket to hold the base using a slack adjuster servo bracket. Perfect size and stainless steel.
