Which relay is which?
« on: 01 June 2009, 16:34 »
Does anyone know what relay does what thing. Here's how they're laid out in my '98 16V GTI

Need to know which is the ECU and which is the Fuel Pump?

Fantastic - thanks for this.

Stumbled into this on another site as well:

1 = Carb inlet manifold heater relay
2 = Fuel pump relay (MK1 & Early MK2/Rocco K-Jet)
5 = Shift light and MPG gauge
15 = radiator fan
17 = x-over relay, 40amp?
18 = x-over relay
19 = front wiper intermittant relay
20 = rear wiper non-intermittant relay (when you push the stalk forward, it'll only wipe once, no intermittant!)
21 = hazard/indicator relay
30 = MK3 (GTI 8v or 16v?) ECU relay
32 = MK2 digifant ECU relay
36 = seatbelt warning relay (possibly headlight warning too?)
53 = misc equipment ignition switched relay (horn, fogs, leccy windows etc)
67 = MK2 16v/ MK3 VR6 fuel pump relay
72 = rear wiper intermittant relay
74 = carb decelleration cut-off
80 = MK2 digifant fuel pump relay
99 = front wiper variable intermittant relay
109= VR6 ECU relay
133= aircon relay
167= MK3 & MK2 16v fuel pump relay
