Great question. I do have an extra relay. I thought it was the original one supplied that later got upgraded to the two post. Funny enough the documentation, while updated, did not provide details about where it should be mounted. Maybe it gives the option to wherever the owner wants, but a best practice/simplest approach would not have been hard to add in. The bracket I have on mine is a little different looking than yours. Mine has 3 screw holes across and looks more horizontal in nature where yours looks more vertical. I will most likely use the same install place as yours and will possibly need to get a little bit longer screw to allow for the additional thickness of the relay.

I have none of the original AC components left besides this wiring harness. If I ever decide to add a second I'll probably run all new wires for them. I'm hoping the climate is not harsh enough to warrant a 2nd condensor.
