List of relay numbers, don't take this as gospel though, refer to the relay location guides above if possible!  Let me know if you know any more numbers or any below are incorrect:

1 = carb inlet manifold heater
2 = fuel pump (MK1 & Early MK2/Rocco K-Jet, no rev limiter)
5 = shift light and MPG gauge
17 = x-over relief (disables most ign live items while engine turning on starter motor)
18 = x-over relief (disables most ign live items while engine turning on starter motor)
19 = front wiper intermittant
20 = rear wiper non-intermittant (when you push the stalk forward, it'll only wipe once, no intermittant!)
21 = hazard/indicator
23 = switched relay, often used for electric windows
24 = switched relay, often used for horn or fogs on older models
30 = MK3 (GTI 8v or 16v?) ECU
31 = 'time control unit' fan control (fan after run)
32 = MK2 digifant ECU
33 = headlight washers
36 = headlights on warning (possibly seatbelt too?)
42 = coolant level sensor control (pre-90 & digifiz dash)
43 = coolant level sensor control (pre-90 & digifiz dash)
53 = misc equipment ignition switched (horn, fogs, leccy windows etc)
57 = k-jet 8v idle speed control relay
61 = decelleration cut-off for carb models
62 = fuel pump (Later MK2/Rocco/Cabby K-Jet, built in rev limiter)
67 = fuel pump (MK2 digifant, 16v and MK3 models)
72 = rear wiper intermittant
79 = ABS system relay
80 = fuel pump (MK2 digifant, 16v and MK3 models)
83 = control unit for syncro freewheel lock
90 = fuel pump after run control unit
99 = front wiper variable intermittant
103= glow plug
104= glow plug
109= early VR6 ECU relay
133= aircon
147= aircon
150= starter motor
167= fuel pump (MK2 digifant, 16v and MK3 models)
174= rear wiper
179= ABS control unit relay
191= hazard/indicator
192= intermittant wash/wipe for models w/rain sensor
204= 40a, fog lamp, electric fan etc. pinout compatible to 53
213= fan, assume radiator?
370= fan, assume radiator?
372= fuel pump relay, 97-05 Passat
389= intermittant wash/wipe
407= rear petrol flap
409= fuel pump relay, 02 Golf
644= x-over relief (disables most ign live items while engine turning on starter motor)

Hi rubjonny

What a briliant effort.

How do I see what the locations A1 A2 B C D etc refer to. Is there a standard labelling system

[rubjonny]

If you click the links on each post, it will take you to a picture of the rear of the fusebox, and will tell you where all the plugs are

[barkstar]

Position 12 on a CE2 fusebox is also the carb manifold heater thingy on Drivers and GLs etc - Relay is numbered 1, Part number 171 906 383. It is exactly same electrical spec as Digi fuel pump relay but the connector layout is a mirror image and just to totally confuse things the Digi relay is part number 191 906 383. Guess which relay was going like a set of castanets on my fusebox today?
