Just got a 2023 Silverado Custom Trail Boss. I didn't notice at the time but doesn't have the factory trailer brake controller, does have the tow package. I've ordered the Curt Spectrum, looks like an easy install except: The cover where the oem controller goes, as I understand, pushes in and not pried out. It appears to me that I need to remove considerable amount of trim to access the back to remove. I have seen videos where folks have scarred it up pretty good and I would like to avoid that. My question is, can the holes just be drilled to mount the spectrum with the cover in place and just chase the harness thru the hole? I know there is a dummy connector but does not appear to be in the way.  Thanks

GM accessories sells that controller.

Did you buy it there and get install instructions with it? 

 

This is the pic in the accessories section, but it's the pre-refresh style dash.

The controller is just like the picture you posted. Got it at Chevyparts.com $198.00 with coupon. 

Update on the install: I drilled for the bracket with the panel in place. The wire was easy to fish thru, did not have to remove a thing. There are several videos out there and one pushed in the small panel where the brake controller goes and one removed the whole bezel, way easier my way. The controller matches the knobs in the truck and actually looks pretty good.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      2027 GMC Sierra: Official Discussion

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.

      from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.
