No, you'd have to add pins for the aswc wiring.

I purchased a sacrificial 70-7552 and pulled the pins from that one to add to the 70-7553. Same size pins but that harness is cheaper. Went to local electronic store and tried to get just the pins but they could not easily match them. As a bonus, leftover pins can be used to do the cross connections for the bluetooth module without any need for splicing in the harness.

Yep, that's what I do, bought a set of pin removal tools as well sense I do it often

Great advice, Thank you!
 

Got the Metra premium audio harness 70-7553 for Nissan and just finished the re-wire. I just want to say big thanks to Bigaudiofanat. It was a simple 5 wire solder swap to make this change. Results as expected were great. I did have to move the 2 SWC cables to the new harness plug. Everything works, audio levels are very well managed now. It is too bad that the original adapter plug manufacturer did not offer a premium audio style plug like Metra does. No matter.

One more thing. I picked up the Sopoby heat shrink solder connectors on Amazon. They worked great for the re-wire. No messy solder to contend with, just a decent micro torch to melt the tiny solder donuts and heat shrink the tubing around the wires. Two birds with one stone.

Did you do this so you wouldn't have to cut the factory wires on pins 6 and 16 when hooking up the aswc-1?

yes did it for pins 6, 15 and 16. No cutting into the car's harness this way

Thank you very much. :tiphat:

Rewire completed
 

Got the Metra 70-7553. Did the rewire. Used extra pins from my other Harmony audio harness to connect the SWC inputs. Great results. Audio levels are now normal. Big thanks to Bigaudiofanat. For a simple HU replacement, still well under $1k, I am very happy the way it turned out. Not alot of effort required to carry this out. Just be able to solder/heatshrink to connect simple wire harnesses together. All the other options (camera, backup cam...) are cake compared to the base HU install.

DIY is the way to go on this. You will definitely know your system when you are done modifying it.

I am in the DFW area. I would like to see if we could meet so I could talk to you and do the same!

Sure, Happy to.
 

@Speedygreene,

I am happy to meet in the DFW area. PM me your info. I have an extra Joying factory harness up for grabs too. It has the entire adapted harness for a direct plug in. It is for non-bose factory audio. I can't use it. For a bose setup you will need the Metra 70-7553 harness adapter. Let me know.
