Thanks. Now just need to track down the harness so we can connect everything...That seems to be the trickiest part of this.

I haven't seen a how to or pics of an install either. I will be doing so with my Yukon.

 

With pgamboa's help, I've identified one of the connectors and think I've found the other for the switch. I'll be making a custom harness.

 

The main difference b/t the trucks and suvs I can see would be the cluster visor. They look to be shorter in length than the suvs. Does anyone know if GM offers an HUD in the trucks as an OE option?

Sorry for all of the probably dumb questions but does the HUD project through the crash avoidance display? Can't imagine cutting a hole in the top of the dash..that would be a deal breaker for me. Anyone have a pic of where the switch mounts in a Tahoe? Just wondering how the switch placement would work in a Sierra given the different dash setup.

Yes it does project that

I assumed this was all in regards to the Silverado and Sierra since it is in this forum section.

Ok..one less thing to worry about. Now I need to figure out how the switch and wiring would work then maybe we could do a tutorial once someone figures it out for the pickups. The SUV's should be much more straight forward since the HUD system could be ordered in one of those..not so in the pickups.

On the suvs, I believe there is a larger and/or separate opening for the HUD in the cluster visor. Chris, please correct me if I am wrong. If there is, and GM offered it in the trucks, then that would address the cutting issue.

The HUD switch is mounted to the left of the steering wheel just under the vent in the suvs.

Like I said sadly I've got no knowledge of this outside of programming probably at least 20 truck clusters for it over the years. I have not had anyone contact us saying it didn't work etc.

I don't see a cover in my Sierra Denali (its a 2017). Just the crash avoidance display.

Understand..appreciate the help nonetheless. If we can figure this out for the trucks, that 20 number will probably go way up :)

Cmatt--If you look at your Tahoe can you see if the additional opening is in the separate front defrost panel that the crash avoidance is in? If that is there is a chance that 'might' be interchangeable with the trucks. Somebody (me) might have to take a chance to find out for sure.

So the cluster visor part# in cocoa for the Tahoe is 23181840 which indicates it is for the hud. The non hud visor for the Tahoe in cocoa is 23181849, completely different number for the Sierra denali in the same color with no option for an hud version. This tells me it will not work in the trucks unless I'm missing something or they use two completely different part numbers for the same part on different vehicles.

The crash avoidance module in the pickups is not capable to HUD info as you would need to replace the crash avoidance module with the SUV's HUD unit. There are atleast 2 different p/n's for the HUD as GM has made revisions of which I don't what the changes are from my research though but a big price difference between them with the superceded p/n. By the looks of everything, there will be some needed modifications to the pickup dashes to get this to work and look decent. I haven't been able to test stuff as I'm still waiting on my cluster as it's still on backorder. The SUV defroster vent panel and cluster visor MAY work WITH modification of the pickup's dash behind its cluster visor but again haven't been able to test yet. As for where to mount the switch, I'm still looking for ideas since I have the trailer brake controller, there is limited space for a clean install.

I just saw your post CRApex (I'm on the app). Sounds like we're thinking the same.

    • are there any codes? with lots of rust, perhaps disconnect/clean both sides of the connection/examine cable ends (the wires) for corrosion going into the sheath & replace if necessary/reconnect ALL the power AND ground cables between the battery, engine, frame, cab, fuse box and starter charm.li (website) has a no-start diagnostic procedure you can work through to get it working.
    • Its no wonder you've gravitated to the oil types and brands you have in later years after trying certain brands and one being a specialty oil or at least very hard to come by up here and the other would have been a commonly found oil of the era and the vastly different outcomes as a result to using the vehicles in question the same distance for an OCI . It shows what marketing hype can do without actually having the product to back up the claims and that is no different now with the insane claims that are written on the side of a bottle of oil from some of the off the shelf oils.    What has surprised me and I was already finding this out before I bought my truck with the GDI engine, that this newer fancy technology that seemingly would suggest better fuel economy/emissions with this high pressure spray of fuel is not in reality kind at all to the engine or at least the oils life. Yet they insist on claiming long OCI with this technology just like they did with the port or similar type fuel injection systems when in reality its a step back in oil life to have a GDI system.    I think the mistake your making Grumpy is that your not sending your samples to Blackstone and getting the feel good glowing report that you can run it another 1000 or more miles and then send another sample where they say run it yet another 1000 miles and on and on it goes until your sending in something that looks a lot like road tar and then they may suggest you change your oil within the next 1000 miles 😆
    • I am guessing that engines of that design back then had a better ability to be abused and survive longer than a new design engine with the long timing chain and the overhead cams and phasers etc. But I would never guess that an engine could go that far and not fail spectacularly or at least die a slow death. 
    • In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them. 
    • I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.
