Washer bottle wires? ( 1990 -110 / now with V8)

I am being driven mad as I have the plug which has green and black wire attached which runs to the pump for the screen washer but I just can’t find the end that it plugs into on the loom. My washer bottle is not original and cable has been extended.
Would the original have been in the passenger side wing and should the opposite plug be there somewhere?
I don’t really want to rip dash out to try and follow it back so any pointers of where to look would be useful.

Yes, its on the nearside.

It’s in the loom does not plug anywhere else.Goes back to fuses/switch

Thanks all, I was looking for a two pin plug but the plug from the loom has three pins - all sorted thanks
