My question is about the wiring harnesses in the 2014+ trucks, specifically my 2018 2500 WT with 7” factory radio. The one thing that I am not very please with in the truck is the factory sound system. I understand this is a WT truck and it is not the premium sound, but the quality and separation of the sound leaves a lot to be desired. I am in the initial phases of putting together a fairly basic and clean system that will allow for expansion should I want to. I have decided to go with the Audio control LC-6.1200 because, I’ve used these products in the past, I love the flexibility and the built-in DSP will make integrating into my factory source easier (at least I hope.)  I am not a fan of the line converters that add RCA outputs so I want to run line level inputs from the source, to the amp, then back to the source to feed the speakers. I do not want to cut any of the harnesses or T-tap into the lines. If I can, I would like to avoid having to run all new wires from the amp to the individual speakers. I would like to make a harness that plugs in between the source and the lines out to the speakers.

 

Question 1. All the line out to the speakers appear to be in the green plug, I have found Metra 71-2107 reverse harness (male end) in the catalog, but I have not found anything that is clearly ID as the female end of this connection. I did find the Metra 70-2057 and it appears to have the female plug that looks like the 71-2107 will plug into, can anyone verify this?

 

Question 2. If they do connect, I assume some pins may need to be moved to allow for proper interface?

 

If I have the incorrect part numbers, or someone knows of a source for the correct harness, pointing me in that direction would be appreciated.

Did a little more research and it appears Spiral Audio makes a plug, non-premium harness that doesn't cost $100, 

Spiral Audio WH-0040 should do the job, simply looking at the pictures, I see believe I see all the speaker wires, constant and ground. I assume the red is to add the ignition signal since I believe it is in another harness. I am going to purchase this and the metra reverse harness and see how many pins I need to add, if any.

I can make a harness for the green plug systems(I05-IO6) for either just adding a sub amp or full system installs.I charge $40 and will come with a 12v,ground and up to 4 channels of high level output.

      Some Assembly is Required

      By Grumpy Bear · Posted

      Missing pieces of the Assembly   Detergency vs Solvency   Not the same thing. Detergency is the mechanism that surrounds solid particulates preventing amalgamation. Usually accompanied by a Dispersant whose job it is to keep those encapsulated particles in Suspension. Solvency keeps things that can be dissolved in solution.    Salt is a solid that can be dissolved. Pepper is a solid that cannot be dissolved. A detergent/dispersant is effective on pepper but a solvent is more effective on salt. As long as the solids remain in either state, dissolved or dispersed then they can be be removed with the oil upon change.    How many wranglers does it take to herd cats? Depends on how many cats your herding. How much sponge does it take to soak up water? How much water is there to soak up? Point is most oil blends start with some herding ability and next to zero sponge and recently even fewer wranglers are being sent to do the same job.    So you start with a dozen cowboys and zero cows but at the drive progresses you pick up cows along the way, but not cowboys. At some point you have more cows that the wranglers can handle and some leave the herd. Deposits. And the API has an acceptable number of cows they are willing to let loose. In the ideal world zero is the right number for he rancher but to the butcher....a few lost is fine. This cow is beat to death. Let's move on....   Solvency isn't something oils on the Walmart shelf care about AT ALL. Problem is, you motor does. Fuels driven varnish sticks rings and only a solvent can keep them in check. The bet is that the solids driven portion that plug the expander rings and the oil drain backs and VVT screens and AFM screens will be an issue long before varnish is. Not that it wont be but if they market well enough the consumer can be kept ignorant enough to either believe it is "normal" (A quart in 1 or 2K is normal) OR is kept at bay longer than the first owner is likely to hang on to the unit. Solvency cost money.    Now the OEM's have John Q. Public buffaloed into the belief that the number cows accumulated along the trail is a known and predictable CONSTANT. It isn't. Nor is the rate at which they crossed paths with them. Only the number of wrangles is constant. Or was. Each new generation of oil sees fewer and fewer of them.    So what happens when the number of cowboys is lower (lower TBN) with each seasons trail but the trial is longer (OCI) and the number of cows along that trail continues increase? (Conditions that promote deposits).    For awhile the blenders were on to something. Better bases are harder to degrade (fewer cows) but that was overtaken by a longer trail (OCI) and improved breeding (More cows) while continuing to reduce the cowboy staffing levels (TBN/Aniline #).    Marketing has been successful. We've fired most of the staff, cows breed line bunnies, the trail is ten times longer and we've convinced the boss his ranch is in better shape that it ever was.    That kids is just the cleaning side. The side few pay attention to.
