I am only using one oil sensor of any kind. The stock one from the V6 and it's put into the stock location for the 5.3 sensor. It has the single tan wire going to it.

I took the wire that went out of the stock truck relay out of the box, and wired it to a standalone relay on the 5.3 harness.

It seems they should have been isolated form each other that way, that's why it confuses me.
