What does the Relay on top of the fuse box do?

[science 0]

On my 93 VR6,

What does it do?

[J.C 10]

From what I can gather, relay 53 is a standard relay and could control a multitude of things,

I'll have a look at the wiring diagram and see if I can trace those colour wires

Looks like it could be

J208, (HO2S) heated oxygen sensor control module, which supplies voltage to G39 HO2S heated oxygen sensor, when the engine control module power relay is energised

red/yellow wire supplied from fuse 18, to confirm check voltage(to earth/chassis) at R/Y wire with ignition on, (12Volts), then remove fuse 18 and test again, should be 0Volts

Electric windows.

When I did my 24v wiring, that was for the lambdas/Heated o2 sensor.

Thanks!

It's my Lamba that isn't working.

I thought the window relays were behind the rear panel?
