08 R350 Tailgate won't close - 974113 & 994513



I've done some research on these codes. I don't find much on 974113. But for 994513, it appears likely that the strip needs replaced. It also seems that these pinch strips can be difficult to source, or are very expensive. So one solution is to use resistors to trick the car.
Is there anything special about these codes being together, that 974113 occurs if you have the failed pinch strip? Anything else I should look at besides testing and confirming that the passenger strip has infinite resistance, and is therefore bad? Any any all advice gratefully received.
I also heard you can add resistors to the connectors to fix the hatch closing issue. I haven't tried this and would like more instructions on how to do it. I'm not mechanically inclined enough to figure it out on my own lol
Thanks for the help though
