Success! DSP Amp Replacement Adapter Harness (With Wiring Pinouts)
Reason for this is I am going to create an adapter harness for my aftermarket amplifiers using a, presumably, broken DSP amp I bought off Ebay to harvest the connectors. Will update this post with the results of that this weekend (hopefully). I apologize for the large image. I use a 32" 4k monitor so it all fits on 2/3 of the screen for me. If you want the excel file to make it easier to read, here it is: Gdrive DSP Xcel Link. If anyone sees anything that needs correction, let me know. Hopefully not as it took me 2 days to make because I am slow and easily distracted.

If you can successfully create and duplicate that harness, that would be a hit item in these pages! I’m certainly interested!
Good luck, CW.

Well... it's not fun to do. And it won't win any beauty contests... but everything tested out with the adapter harness and the diagram is correct. All speakers responded to 3v button cell battery test.
  The big one is pretty easy. The 26 pin one is not as "fun."  No soldering station shaming please. That thing has been serving me faithfully for 15 years. Though, lol I guess I could get a new sponge for it. Also I do need a higher temp iron. This one had a rough time flowing the solder well enough to loosen the pins when removing connectors from the DSP amp board. Helper station is a MUST. Impossible without it.  And the almost finished product. I could have depinned the unused connections but meh. Now that I know polarity is good, connections are correct, and there are no bridged solders/shorts, I need to seat the back of the connectors in something. Do you guys recommend silicon sealant (like gasket maker) or maybe an epoxy? I was thinking of building a form around the connectors and filling with silicon or epoxy. I want the harnesses to hold up to plugging/unplugging forever. I'm leaning epoxy.

Yep, epoxy is your friend here. All our motorsport connections get epoxy on the boots and on built potted connections.

Unfortunately I don't know the name of the product but it's basically a softer epoxy or REALLY hard silicone depending on how you want to look at it It's regularly used in the boating industry to coat the back of PCBs for waterproofing or to make security modules and other electronics tamper proof. I'm guessing one of those 2 part syringe epoxies would work also but it might be too runny
