2-Speed wiper wiring diagram / switch pics

Recommended Posts

This is currently the source of more confusion than I expected - does anyone have a diagram that actually shows the 2-speed wiper wiring for a Series 3, and/or a picture or diagram of the correct switch an the wires going to it?

Well spotted :hysterical: I would have sworn black was white I had 2 speed wipers, mind you, note yesterday's date ;)

I've a late series three with the 2 speed switch, plus wash. 

Do you need a photo of the back of the switch?

That would be great if you can get one, yes!

The only difference with two speed is there is one more wire to the motor.  ULG is the high speed. NLG = off, RLG = low speed, LGB = wash, G = power.

Well that's the theory but no-one seems to have a 2-speed switch (part no 575146) or even a picture of one, and the one I sourced from eBlag is not actually internally wired correctly for self-parking if you use the regular diagram as you posted. So there's a discrepancy somewhere in all this.

It would work with a Defender wiper stalk, but not the rotary-type switch, at least as far as I can find.

So, the question remains as to where the real differences are and what an original install looks like.

I converted my 2a lightweight to twin speed with park using a series headlight switch, if any use? Didn’t require any cutting into loom either.

Fridge, what makes you say it isn't wired for self park?
As I understand it, that is all internal to the wiper motor....

That true. There's a little plastic on thing about an inch long on the motor. Permanent live to the motor?

Thanks Gazzar those photos are absolutely bang-on!

The self park feeds back through the switch on the Brown/Light Green wire, which is connected to the SLOW speed contact when switched OFF... and thanks to @Gazzar it shows that the switch I bought is NOT the right thing despite being advertised as the correct Land Rover part number.

My single-speed switch looks the same as Gazzar's but with one fewer terminal. All makes sense now!

Thanks all.

I used a Cole Hersee Switch.  Fits the stock location and you get variable intermittent.  Works great.  https://www.littelfuse.com/products/switches/windshield-wiper-switches/electronic-windshield-wiper-switches.aspx

They also do non intermittent ones: https://www.littelfuse.com/products/switches/windshield-wiper-switches/electrical-windshield-wiper-switches.aspx

They look great! An all in one solution, probably stick one on the Moggy.
