Hey guys, 

 

I went into my tail light assembly to hardwire an led tail gate light bar. With what I seemed would be an innocent project had my scratching my head…I went to expose the wire to splice into my light bar wires with the truck turned off. I go to turn it back on and it says “check light assembly. Sure enough no power to the back left but right works just fine….thinking it was a fuse I went in and changed what I believe is the fuse # but still nothing….could I have shorted the whole assembly??

I tapped my marker bar with the clear LED backups into the left tail lamp and the B/U lamp circuit and have never had an issue. I did my 2021 and my 2024 the same way.

you will need a scanner to hook up and clear codes in the bcm, it thinks the light is shorted and turns off the power

 I went in with my own scanner, found a code, deleted it, but check engine light is still on and assembly is still not working. Will a standard OBD-2 scanner not work?

Another quick update. I got the code out and engine light is gone but assembly still not working. Is it really possible I fried the whole assembly now?

      Injector update

      By iso221 · Posted

      Because single shot injectors are ancient and multi hole injectors provide smoother running engines and sharper throttle response due to the fuel being atomized better..the best lead I have is a 24lb blue top injector almost everything matches up but the injector will put out about 26lb/hr which is just outside the gm threshold.figured id ask here to see if there was an absolute answer

      Injector update

      Why is my question?   Any change in injectors requires a tune. Unless you are going back with the OEM part number or a newer part number of that same injector.   Any size difference or type difference like the EV6 style injectors all have different injector data for them. And there is no EV6 injector that matches the factory 25 lb/hr size that your truck comes with. I've been messing with these trucks and tuning them for a long time and what you trying to do doesn't exactly make sense to me.

      When a condition becomes a business model.    https://www.gm-trucks.com/gm-truck-suv-incentives-pricing-2026/   Zane posted this in "Latest Articles".    The honest bottom line   Truck buyers have spent three years assuming this is a temporary condition that will break once inventories normalize. GM just presented it to investors as a durable strategy, on a chart, as evidence of good management.   Inventory did normalize. GM is at 511,000 units and squarely inside its own 50 to 60 day target. The discounts still did not come back, because the low incentive number is the goal rather than a symptom of shortage.   Plan your purchase around that reality instead of waiting for it to change. Follow our ongoing GM News coverage for pricing and incentive changes as the next-generation trucks land.

      Thought it was raining this morning when we woke. Nope. Dew point was over 80 F and humidity 98%. Zero visibility distance. Everything was 'sweating'. I've seen rain come out of clouds but never out of Pepper or the tree trunks.    Wicked storms just missed us sliding off to the east but by blocks. Heat index about 110 F with air temp in the 90's.    This is  our third wave this month of multiple days of this type of weather. And yet the grass is going dormant and the ground is cracking this side of the street and water up the the hood opposite. Just weird stuff going on.
