right iv got my mfi engine in my fiesta xr2, i know its an escort section so sorry. but im having trouble putting plugs in the right place etc.

iv got the blue, yellow, brown ones right, but iv got a grey one which need to no where that goes, a 3 pin one and also on the loom say 14" down the line from one of the ecu's there 2 wires branching off for a plug, but the plug has gone and someone has just replaced it with 2 spade connector parts. wires are brown and brown/green but think most plugs are that color

how do i know what that goes to

pic of your bay and metering unit would be good

cheers lew
