Holy Automotive Engineering Batman!!!!
I need to take time to read and digest the information you provided. I have checked the 4Lo circuit end to end and it works according to the supplementary service manual. I have removed for a test the reduction box in the cable so i feel confident that it is triggering the P1875 code because of the differences in sensors. There have been NO other codes triggered.
I'll see if i can call in some favors and see if I can a scope hooked up to see what I can gather to help me understand more.
It doesn't look like from what I am reading here is that using some form of 'off the shelf' box is not going to be possible.
Thank you for sharing. It is very helpful.
