disco wiper motor wiring

Can anybody help with wiper motor wiring using the existing twisty switch?

I'm rewiring disco and wipers are last thing on my list...honest

Iv found what feds the motor for the 1st speed and fast speed but need to know how to wire it so I get park and intermittent back if any body can help...stuck it here rather than disco section as I figured somebody will have done it on defenders and series motors too.

Cheers

If I remember correctly, the wire colours are:-
Black goes to a good earth.
Red/Light Green ... Delay Wipe
Blue/ Light Green ... Slow Wipe
Brown/Light Green ... Fast Wipe
Green ... Permanent 12V feed

does the disco have a relay like the fender .

i lose park and intermittant if i pull the relay with the wires the same colour as the windo wipers out .....

soon as i plug it back in it all works grand.

According to RAVE there are 2 relays so need to work out how they are used but thanks for the cabling. ..iv managed to wire them.through a fused switch at min will try get them on a relay tomorrow..need to.wprk out stalk wiring too
