2014 silverado wt radio and hmi upgraded to i06

 

This truck never had a back up camera. Upgraded from i04 to i06 via hmi. installed proper back up camera in tailgate, plugged in to RC port. BUT

 

The error from the ecu indicate that the line is open. So, my thought is that the wiring is not there. I was told if the grey and yellow wire are there its there, but even if it is from the back to front, it might not be across the front to the unit.  I was temped to use a harness that would plug into that plug and add a simple rca add.

 

So I have a black screen with  directional lines that work. Then it goes black and days service required.

 

I took it to the dealer, they want 1200 to do it all. uh, no. I need a simple solution. help guys. please.

Check if the camera is getting power when you put it in reverse, it probably isn't.

If it doesn't, you can tap the backup lights to power the camera.

I had an electrician test it an you are right. No power. Which leads me to think it's not prewired at all. So anyone have any idea what wire harness I need? And where to plug it into?

And if I do tap the reverse lights which of the six wires do I use?

From all I've read, your harness should be prewired for everything except the 12V power for the camera when in reverse. 

For the reverse lights, you want to tap the 12V positive to one of the lights (you can also tap the trailer reverse light for this). I'm not sure which one this is, but you should be able to tell quickly with a multimeter.

I know which wire on the truck to use for power what I don't know is which wire on the camera plug is power. Either the wire color or pin number? Due to the frame I can't get to the plug on the truck to test. Can't take the mod off cause can't get to both bolts. So I need to know on the actual plug the pin number or wire color. Thank you!

      Good question, I don't remember for sure but I believe it was the HD. I will check and get back to you.

      OCI, not when but why?

      Point of the post sir was that while both wages and cost are rising EVERYWHERE; the cost is rising faster EVERYWHERE than the ability to buy EVERYWHERE. We're not going down the location rabbit hole. I'm aware of what economic migration is. I've lived in four states including Texas.   It's what "Purchasing Power" means.   I'm not telling you what I think. I'm telling what the government, your government, data shows.   It wasn't an argument. It wasn't a suggestion. It was a statement of FACT. You are absolutely entitled to your own opinion. Your not entitled to your own facts. If you and I were, they wouldn't be facts.    fact /făkt/   noun Knowledge or information based on real occurrences. "an account based on fact; a blur of fact and fancy." Something demonstrated to exist or known to have existed. "Genetic engineering is now a fact. That Chaucer was a real person is an undisputed fact." A real occurrence; an event. "had to prove the facts of the case."

      Transmission jumping out of gear while driving.

      By JimCost2014 · Posted

      Probably a one and done post, but do you have a CEL on the dash? Was having issues with my transmission, fortunately only a week, and it turned out to be the transmission harness. Valve body was in good shape, so new harness with all the sensors attached, new fluid, and filter. Seems to have worked so far?

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Two interesting tidbits of information which are NOT related were just released.   One, regarding the possible thrust bearing issues / engine failures with the 3.0. Demonworks just did a segment in which they believe they may have found "a" or "the" cause of thrust bearing failures: A missing thrust bearing. If the engine doesn't have all its thrust bearings from the factory, the missing bearing can cause extra play which ends up destroying a nearby thrust bearing which then sends metal through the engine.       Of other importance, Lake Speed Jr released some interest information regarding oil weight selection for the 3.0. Comparisons of:   AcDelco 0w20 Dexos D Mobil 1 ESP x2 0w20 Dexos D Mobil 1 ESP x2 0w30 Mobil 1 ESP x4 0w40. Mobil Delvac 5w40   Spoiler alert: The Mobils are PAO Ester -base and the ACDelco is a Group III base. Mobil shows lower wear in their tests for similar weights. Additive packages between 20-30-40 weight ESP's appear to be the same, but only 0w20 is Dexos D licensed. Wear is even more reduced with 30 and 40 weight ESP although all perform very well and resist shear and provide very similar viscosities within temperature operating ranges in the 3.0.   There are even more surprises, so just go watch it.

      Weird click noise when revving my truck?

      By JimmyB4 · Posted

      Hello Guys I'm new to the form,         I just put a 7-inch Rough Country lift on my 2016 GMC Sierra 1500 with the 5.3 and I also put a Borla exhaust on it. But I noticed when I'm in park or in neutral and then I rev my truck up really quick there is a bad click noise and I think it's coming from the motor somewhere. Anyways I got a video of it I will attach below I was just wondering if you guys think its rod knock or lifter tick or something like that because I know the AFM kind of made the lifters weak on these trucks.       Thanks!!!!!
