Hi All. I have an '04 Avalanche Z71 with a hitch, and the auxiliary harness was included when I bought it this past summer. Here's what I want to do, and I'm wondering if any of you have done it or, or have any tips. I want to install a trailer brake controller, but want as slick and integrated an appearance as possible. I'm eyeing the in-dash cubby to the right of the HVAC and audio controls. Here's one install I found that's along the lines of what I want to do:

The brake controller needs some pretty large/thick wires. I think it would be problematic and possibly dangerous running wires with that much amperage through the dashboard. There's not a lot of room/clearance behind the radio and climate controls. Just my $.02. I've installed brake controllers in three trucks, and I've tried to keep them as simple as possible.

Just mount it below the steering wheel at the bottom of the knee bolster. Easy to install, controls knobs are accessible, and you have to pay attention and look to even notice it.

I installed mine just below the little cubby that's below the HVAC controls. (same dash setup as pictured) There happens to be a dash screw under there which can be used to hold the brake controller. In this spot, there's no risk of banging it with your knees, etc. and the factory harness easily reaches over from the wiring port on the left side. Zip tie the harness cleanly under the dash and you're all set.

If the wire sizes are a problem, you can install relay(s) in a hidden area, run control wires from the dash to them and the larger wires from the relays to the rear. Std solution used by the car mfgs - as the cars got smaller and the electronics requirements went up, not enough room for large wire harnesses, so the relays were employed and moved to the engine bay.

No offense, but a relay is a terrible idea. It will delay the application of the trailer brakes, and if it fails due to corrosion/etc, now you're in a bad way. Nothing better than a half-second delay on brake application when you have to make a panic stop and your GCWR is 16,000 lbs.

 

I like clean installations, too. I don't like the look of bolted on/added on crap. But with such an important safety device as a trailer brake controller, function overrides form. Every time.

      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!
