2007 SJB Wiring

I had the passenger leaking problem and need to change the SJB, I haven't found one that fits my car but I found one that is almost the same, the problem is that in the back of the SJB in the upper left corner there is a connector with a P1 label on it, mine has it but the one I found doesn't, it has a hole in it and also the P1 label but inside has no connector, does anyone knows what it does or if I can wire the connector so it can be used?
