I have been working on trying to fit the later dash etc into my 95sti.
I am at the stage where its just the later Hazard & rear window defogger switches which need wiring up. The switches are from a 98sti (face lift dash).

The earlier switch when press on illuminates the defogger symbol in the dash clocks, the switch itself does not illuminate.

The later switch has a built in bulb which should illuminate when pressed & nothing on the dash clocks.

Having looked at both earlier & later wiring diagrams I am a bit puzzled as how to wire in the later switch. I have included a link for both wiring diagrams.
The pre96 diagram is correct.

The later diagram is from a 2002wrx model, I could not find the v5 wiring diagram. but the switch seems to have the same layout design.

I am not great when it comes to electrics but just by looking at the later switch picture diagram there seems to be a resistor type system which activates the 2 upper contact? Not sure how this works.

98sti switch wire colour codes
No specific pin order

1. violet
2. Orange/white
3. red/blue
4. black
5. blue
6. green
7. black/white

Whilst working on the speedo clocks I found out that Violet was for illumination power (12v) & the orange/white was illumination earth. This works on the speedo clocks. However does not do nothing when tested/powered up on the switch itself.
The only 2 pin outs that make any connection whether or not the switch is pressed are 3 & 4, this also lights up bulbs when supplied 12volts.

Anyone got any ideas or know how to wire this in correctly.

Thanks Ticky

 

I've got a termainal guide for the 99/00 (V5) but its on paper & I've no scanner.
PM me a fax number & I'll happily send it through.

 

Ive got no fax machine but will try to see if there is anyone I know that has.

Thanks for offering to help
Ticky

 

I'll try to get it scanned at work tomorrow

 

Doh - Wrong diagram !

 

That looks like the rear fog light switch to me?

I have e-mailed you anyway.

Thanks

Sorry Ticky - not had chance to dig through my files yet.
Wifes away on her works Chrimbo do tonight. So I should get enough peace & quiet to have a good rummage
