help needed led'ing switches / switch pinout

[Gaz]

Im not anywhere near a haynes but im trying to led my switches and they arnt all the same internally and ive forgotten my curcuit tester

some are 5 pin some 4 most are latching but the rear heated window one isnt.

All labled 1-5 but the internals of the switch are different ideally i need the pins for illuination, switch light and earth pins for the differnt switches if someone could help

Sorry if this isn't much, but when I removed switches before, i.e. demister and fog switch, to find the live and earth, I got a separate LED, already wired on it's own, then stuck the live wires into the different pin numbers to see when it lit up... If that makes sense. I'm on about the standard LEDs you can buy from Maplin in 4 packs.

as far as i can remember


(top) illumination
middle - blank
(bottom) earth


and on the otherside you have the 3 other pins

Heated rear window switch S4

Pin 4 - Grey Green = illumination +ve
Pin 1 - Brown = Illumination -ve (ground wire)

Pin 5 - (colour not stated) = tell-take +ve
Pin 1 - Brown = Tell-tale -ve

(Note the -ve side of both leds are linked within the relay)

Pin 1 = brown = goes straight to ground / chassis.
Pin 2 = black white = feed to latching relay and the mirror demister
Pin 3 = blue/white = alternator / charge circuit controlled live feed to relay.

Hope that helps, as the Haynes manual is quite confusing on Switch S4.

Thanks rob i'll have a go later

Follow the numbers for the relay pins, NOT the socket pin numbers.

for some reason Haynes / Vauxhall took the P!$$ and numbered the socket pins differently.
