mysterious black box

[Max Allan]

Converting the US style "running lights" on my Brooklands Ace to side repeaters (MoT requirement) I came across this mysterious box in the void behind the front offside valance. It looks quite important, with lots of wires, and my initial thought was it was the illusive ecu I'm trying to locate. But it's not the right size and the Ford part no. F48F-12B577-AA doesn't tally with ecu numbers. Any ideas?

Max this box is what Ford calls a constant control relay module... it controls cooling fans speed, AC clutch .... they say fuel pump but Ilm not sure what that would have in relationship to the temp of the car ... if you google it .. it will tell you how to by pass it with a manual switch.
