Fuze box wiring layout . Relay locations . Fuze locations .

Most commonly asked question seems to be about relays and the fuze box layout . The fuze box is located above where your passenger's feet are .     Here are some pictures of the fuze box taken from a 1983 MK1 GTI [series 2] . If you have an early Series 1 Golf with the small fuze panel , more information can be found at bottom of this post . If the relay is NOT fitted its not used on your model  . Some early series 2 models had a series 1 style fuze box with xtra relays and fuzes mounted on the top (eg. Fuel pump relay with built in fuse ) .



There are 12 relay positions fitted BUT only 6 are used in this 1983 GTI model .

layout for later cars and Cabriolet is below . DO NOT fall in to the trap of thinking that the relay is missing ! It may never have one or needed one . Lights for instance on all MK1 models never had a relay .  


1 (free)
2 Inlet manifold heating (Carb) / Fuel pump (Inj) / Glow plugs (Deisel)
3 Seat belt warning system
4 Gear change up display (Formel E, GTi)
5 A/C
6 Twin horn
7 Fog lights
8 X relay
9 (free)
10 Wash-wipe interval
11 Rear windscreen wash/wipe
12 Hazard warning lights
13 Seat belt warning system
14 Seat belt warning system
15 Headlight dim-dip
16 Cold start valve
17 (free)
18 Coolant temp gauge (Inj, Diesel)

List of relay numbers , marked in white on top of the relay [thanks to rubjonny for info] .

1 = carb inlet manifold heater
2 = fuel pump (MK1 & Early MK2/Rocco K-Jet, no rev limiter)
5 = shift light and MPG gauge
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
30 = MK3 (GTI 8v or 16v?) ECU
31 = 'time control unit' fan control
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)
62 = fuel pump (Later MK2/Rocco/Cabby K-Jet, built in rev limiter)
67 = MK2 16v/ MK3 VR6 fuel pump
72 = rear wiper intermittant
80 = MK2 digifant fuel pump
99 = front wiper variable intermittant
103= glow plug
104= glow plug
109= ACV engine code ECU?
133= aircon
150= starter motor
167= MK3 & MK2 16v fuel pump
174= rear wiper
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
Fuze layout  


Except for this fuze above relay 5 , used for rear fog lights .



Later Cabriolet models had more relays and had the following layout [Thanks to ew for this info]
