This is what I got @Tonyrodz

20170413_012124.jpg


Mount the camera and run the wire to the main harness. From there run the red and black to the reverse light. From there run the rest of the cable to the deck. Plug in the yellow rca to the AV/in ......and I guess the red wire coming off the rca splices into the reverse trigger wire on the back of the deck?

I know it's simple but I feel dumb, it's my first camera install and Mr ebay never sends instructions for anything lol.
Run the power line for the camera into the power of the reverse light, and ground the black wire from the camera to the body like I did

Then you have to get the Head unit to "see" when you switch into reverse, I tapped into the wire running up the a pillar to the reverse mirror that shuts off the auto dim function when reverse is engaged. There is another wire you can tap into at the BCM, but I couldn't find it well enough.

Exactly what he said @05Single .not hard at all. Hardest part is running the cables and hiding them. We have faith in you! :waytogo:

Chatted to my mechanic last night. Hit him up for some lift time next week to have a look at the front end. Researched some Moog and Energy Suspension parts to see how far we want to go up there. Thx guys info.

Two other issues looking for input.

1. Drivers side power mirror functions are intermittent, as in sometimes they work and sometimes they don't and slow when they do work. Passenger side responds, but seems sluggish. Wondering if the switch on the door panel might be going bad or a loose connection behind the sail panel? Other thoughts?

2. My CHMSL/3rd brake light is out. I replaced the OEM one with a Dorman one last year. Worked without any issues until recently. All tail light functions and cruise control are operational. I replaced the CHMSL 10amp fuse inside by the driver as it was blown.

The CHMSL light worked for maybe one or two brake pedal cycles and then blew the fuse again. Tried a 15amp fuse just to see and it blew. I checked the fuse box under the hood and everything appeared to be okay. Might need to have another look.

Thoughts on where to chase a possible short? The actual harness where it plugs into the CHMSL or elsewhere to help me start somewhere?

Thx guys.

Electricity isn't my forte' but I would reason that if too much power was being pushed out at the light, it would just blow the light. I would check any of the wire before the light to make sure that it hasn't grounded out on the body or something.

Other than that, take it off, and put a voltimeter back there on it and see what you're getting. Something in that circuit is bad.

**EDIT** put the voltimeter where the fuse goes too, and see if that can tell you anything.

Got an alignment today finally after replacing the pitman arm, idler arm, idler link arm, passenger side inner and outer tie rods, driver's side outer tie rod, and driver's side upper and lower ball joints.

She's driving like a new vehicle!!

Just take the light out and test the brakes again. If it doesn't blow the fuse the light is your issue. You can get one at a pick n pull really cheap.

Thx guys. Good points. Will check that harness where is goes into the headliner thru that grommet and see if maybe it has vibrated/pinched itself and grounded itself on the body or if the light is an issue.

Yeah electricity is not my strongest suit, hence my questions. lol but I am learning more and more from this site though.

On that note, I did order another Dorman replacement CHMSL and it would not light up at the time. I ended up sending it back before the 30 day window, but maybe the fuse/light combo I didn't have all working together at the same time.

Ok will give those few things a whirl and see how I go. :waytogo:

Does the fuse blow with the light unplugged? Thinking it may be the light itself. If the fuse doesn't blow until you plug the light in and hit the brakes a few times then that's the problem. Otherwise check where the wiring moves or is next to something that moves,like where it goes into the hatch from the vehicle and the hatch opening and closing can cause it to break down. A visual inspection of the wiring will yield the best results.

Thx Red for backing up those points. Will see what I come up with.

What about that red wire that comes off the yellow rca plug? I figure plug that into the back of the deck instead of running a separate wire to the a pillar. Has to be interconnected in the harness to the other wires that connect to the reverse light. What else is it for ?

Pulled the CHMSL down, popped out the rubber grommet and pulled as much of the wire out as I could. No water intrusion, no chafing on any part of the wire and the OEM foam wrap is still in place. The plug is in great condition as well and no indication of any grounding. I metered the plug and it is pulling 12V. Working methodically just to make sure I didn't skip a simple step, I popped in a new 10A fuse which stayed intact without the CHMSL plugged in. I plugged in the CHMSL and the 10A fuse blew immediately. Just to confirm, I repeated all the above steps and blew another 10A fuse.

Amazon Primed a new CHMSL, which will be here Saturday. Hopefully it is just the light, but based on the input you guys have given me, that sounds like the culprit. Sucks that the CHMSL is only 13 months old. But if it's just the light and not chasing an unknown ground, then it is worth the $40 to get a new light. Will update once the new CHMSL is installed.


Anybody have any thoughts on my earlier drivers side mirror issues?

Also gave her a wash after yesterday's rain and picked up some Lucas Oil Slick Mist Speed Wax at the new O'Reillys down the road.

My vote is the switch but that one is hard to diagnose without having another switch to try. If it's not the switch then further diagnosis is needed.

Thx man. That was my thought as well....Hmmm okay might have to see about a new switch and try that route to see if that gets me the way fix.

Maybe a bad contact connection in the switch. Again bust out your tester and test the leads at the mirror end while someone else pushes switches. Then go from there.
Might also be the gears inside. Have the key in the accessory mode and have someone push buttons form the drivers side. Listen closely if you can hear it , even when the actual mirror isn't moving.

Maybe look for a used but real oem chmsl from a wrecked tahoe/yukon and see if it pops fuses

Good thoughts on the motors. It crossed my mind, but usually think of NNBS mirror gears.

All good points. Thx guys. Will see what I can come up with.

I took my truck in today to have my 26's balanced at my local tire shop where I bought them. I've always had a good relationship with them even though sometimes they do some stupid shit and today was no exception. These guys know me by name, they know my truck and they know my wheels. They're the only 26's they've worked on. They love them but they hate them. So I didn't even look at them until I got home and I see the weights plainly visible even though it looked like they tried to hide them behind the spokes. Then I noticed one was hanging so I pulled it the rest of the way off. We've been through this before. I drove back and reminded them that isn't the way we do the weights on my truck. They go on the inside, at the tire bead, like everybody elses does. Dude says " but they're silver, you'll see them" and I tell him you can't see the inside of my wheel but you CAN see the ones they put on, definitely can see THEM. It took them 2 1/2 hours to do it wrong, now I need to take it back again. I stayed calm even though I wanted to scream at them for wasting my time. I mean, they didn't charge me a thing but my time does mean something to me.
