Thank you for this as I have been searching high and low all over the transfer case and have no point to connect these to. This helps ease my mind a bit as I work to complete the swap.

She's Alive !!!
First start took place yesterday.......starts and runs for just a bit and then dies.
Still need to button up the intake, exhaust and a final wiring connection once I figure it out.
The connection in question is the purple wire from the PSI harness that is to be connected to Brake Signal/TCC Ground signal into PCM.
Not sure which pin this is that the purple wire ties into....any guidance form those ahead of me on where you made this connection would be appreciated.

Excellent, wiring is not my in my comfort zone so glad I am now done with that aspect.
One question I now have based on moving onto the exhaust: Which O2 sensor needs to be placed first in the exhaust i.e.:

The Discovery sensors should be deleted from the Land Rover harness. Your LS harness (assuming it doesn't have emissions parts) should have 2 LS pre-cat sensors. I'd recommend taking a look at the ACE manual chapter on the engine harness wiring just to get an idea what is on the modified harness / what it looks like, especially if ACE did it for you.
Yes, my harness is directly from ACE and it was returned to me with 2 - O2 sensors still wired into the harness. I will read back through the wiring harness information in the manuals and if necessary reach back out to ACE for clarification on the Rover O2 sensor plugs that still remain in my harness.

It took a week or so but ACE will give you access to the documents you need in the “owners” section of the site. There are 7-10 PDFs with the process. My advice is to start cleaning and stripping down that LS block, swapping out sensors and seals that need it. That part isn’t covered in the PDFs but will help you get familiar with the LS if you’re not already. When you’re done with that, start ripping that 4.6 out of the Rover. Reach out if you need help.
