Hi guys, new to the forum and first post, I have been reading often though since buying my truck a couple of months ago. I have a 2020 LTZ with a 6.2. I've seen on older trucks being able to have the low beams stay on when the high beams are engaged by jumping a diode between relays. I can't find any information on doing this on the 2020. I've found plenty of info about auto on fog lights but not this. Any help would be greatly appreciated.

Thanks for sharing this, unfortunately it doesn't apply to the 2020. The relay and fuse setup is completely different. There is only one headlight relay instead of one for high and low beams. Also the new style relays completely block the contact points underneath them when they are installed.

Sorry - read the post too fast.  I thought you wanted the fogs on with highs.

How about this one: https://boostautoparts.com/products/6hi

Basically the info is the same but the diodes are much cheaper way to go.   If you want to send me a message with your address ill mail you some for free.   I have a hundred or so left over.

I appreciate that, I actually ordered some that are getting delivered this afternoon. That's why I was doing the research.

its super simple, a single diode between the fog lamp relay control circuit 1317, terminal 10 in BCM X5, and high beam relay control circuit 1969 terminal 18, BCM X5 gets the job done

I went from terminal 10 in the BCM X5 to terminal 22 in BCM X5. The fogs come on any time the parking lights come on (you do not have to push the fog light switch) and stay on with high beam

      Cold start Miss, oil in cylinder

      By asilverblazer · Posted

      Can you sample the pooled liquid, enough to confirm it is oil?   ...That its not fuel or coolant.   Also, make sure combustion gases aren't entering the cooling system.   Simply put, either oil being pushed up past the rings (this really isn't possible), oil leaking past the head gasket, oil leaking past the valve, oil entering through the intake air path. If none of this is likely - it may not be oil.   What could be likely is the fuel injector leaking down. A puddle of gas would still smoke and rough idle. (Same cylinder has the same problem after injector replacement?)   What is the crank time first thing in the morning, when the puddle would be present? Does it seem like the high pressure fuel pump needs an extra second or two to rebuild the pressure that injector 8 may have let bleed off? Check the fuel pressure via a scanner prior to starting the engine.

      Good information!  I didn't know about the dementia aspect and asked for a general for my second knee. I'd heard that recovery room time is usually shorter with a general.   The anesthesiologist talked me out of it and I had the spinal.  Inconvenience and/or discomfort is a small price to pay for reduced risk!

      This is for those over 70 years of age contemplating joint replacement surgery involving general anesthesia. Even some 55 yrs. ago when I took my pharmacology class the dangers of developing dementia in the elderly that had general anesthesia were beginning to be recognized. Over the years there has been some refinement in the cautionary warnings, avoid general anesthesia if possible if you've had close to 10 priors, especially over the age of 70 and/or a family history of dementia. I'm not including the twilight anesthesia induced by propofol often used in cytoscopies or colonscopies. Seriously think about seeing a neurologist and undergo cognitive testing before proceeding if any of those criteria apply to you. Spinal anesthesia may be an option in some cases. I'm in the above camp and although I could use a new right knee, I get fidgety according to a prior orthopedic surgeon when the bone saw spools up or maybe it was the smell of saw blade meeting bone, anyhow I may have one general anesthesia left in me which I will pocket for now and I'm choosing mind over mobility, anyway where did I leave my damn cane!
