Success! DSP Amp Replacement Adapter Harness (With Wiring Pinouts)

Thought I would post this as it might help someone in the future. These are the pinouts of the 4 harnesses on the LCI DSP amp. I think it's the same for all DSP amps but am not 100% sure as I referenced the TIS 4.8is wiring info. I know all of the info in the charts below has been posted before (I referenced some of it to create this) but I wanted to consolidate it as I had to view a few different posts and TIS diagrams/pinouts to get all the info I was after.

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.
