hi, you would have to find out where the multichanger is normall installed on estate vesrions. if its in the boot then the mdule is probably hidding behind the wall carpeting where it should be,, the other end will be behind you existing stereo, the remote lead to the remote stalk on the steering colum may also be hidden just behind the dash.. I hop this helps and I cant guarantee it will be correct but fords are great for extra wiring thats used on higher classed models already being there. I had a 2000 Wreg St24 and the footwell lights had been fitted but as they didnt come as standard on the st ford just left the bulbs out.. a trip to halfords and 2 bulbs later andI had footwell lights,, if you have a Mk2 and dont have the lights get a mirror and check under the glovebox and above the clutch pedal and I bet the light sockets are there (sorry for rambling on)
