Hi, i've just removed an alarm from a fiesta 1.8 16v xr2 mk3 and have a couple of questions about the ford wiring,

1, there as a wire that went to what i think was relay 2 orange 1 next to red, what does this relay do? the wire connected to pin 54 what does this pin do?

2. there was a brown wire going to relay 3 (red one) either pin 86 or 68 what does this relay and pin do?

3. there were to wires that connected to a thick black in the fiesta loom, what are the black wires?

cheers
