Just been towing with this idea for some time. That's considering that all MOT related regulations slowly getting to a point that headlight washers are "must have" with projector lamps. So, sooner or later I would have to do aftermarket system anyway.
Anyway...
We need 3 basic components for our system:
1. Headlamp washer switch.
I don't like idea of hooking washers to windscreen washers. That's because headlight one are "high pressure" so few washes of windscreen will empty tank quickly. Also love to have some independence in operating washers.
2. High pressure washer pump. Important thing - windscreen washer pumps a low pressure one, hence pretty useless.
3. Headlamp washer jets. Obvious choice would be to adapt Galant n/a jets, but I'd rather to go for more discreet one.
So...
re #1.
After some search I had found that easiest to install and quite nice blending with our vr4 interior are switches from Subaru Impreza (1997-2001):
57861
Power supply +12V (from battery via relay driven by ACC) to "blue" pin/wire.
Signal to headlamp washer pump taken from "black" pin/wire.
re #2.
That wasn't easy to find due to size of vr4 tank outlets. Also bear in mind that we can't swap washer bottle for one from Galant n/a with already installed hi pressure pump due to size and shape. We are stuck with our stock tank.
Anyway I've found that high pressure pump for headlamps from Land Rover Discovery Mk I and II, will do job nicely. Pump (Valeo made) is almost p&p (has to be upside down due to size) but will fit perfectly. Pump code is: AMR3661, new can be purchased here:

But used one cost in range from 10 to 16 GBP.
57865
Positive pin: +12V signal from switch
Negative pin: ground
re #3.
There are many different types of headlamp washer jets. Each require different amount of effort and money to fit into our front bumper. After some thoughts I decided to adopt possible cheap and not sophisticated system.
Again, I've found that Land Rover one are quite easy to install and quite discreet.
Also from mentioned website:
http://www.brit-car.co.uk/search.php?xSearch=washer%20jet&xPriceFrom=0&xPriceTo=0&xSort=0&xPage=3
Part numbers are: DNJ000081 (RH) and DNJ000091 (LH)
57864
Over all, once we get all parts we can simply wire the together (pretty straight forward). I rather recommend to use power source directly from battery via relay operated by ACC..
Also water hoses has to be strong one, beware that pump is pushing up to 45psi pressure!
