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?

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.

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

Littelfuse have none in stock. They need a bulk order to manufacture.

So I'm looking at the Smart range, instead.  They're based near Abergavenny. I've asked them what they recommend.

Attaching an drawing I made to use the Lucas Switch that has no power terminal when switched off (for park power). An additional relay needs to be wired in. I marked most of the wire colors as found on the Series III. The switch I used for the drawing is what is available from the market as replacement for the wiper switch.

It is very simple if you are wiring a Marinco afi windshield wiper? There are three terminals. There are three wires, red, black , orange. The black is ground, labeled with black Mark, the red goes to the forward spade and the orange goes to the rear spade.

OK this is getting weird round here - random newbies with 0 posts replying to years-old threads, and this one isn't even relevant to the actual thread???
