Well, the Big Guy has been busy tinkering with my bits again. (Isn't there a law against this sort of thing?)
He had read up on some of the threads here about upgrading to Intermittent Wipers and decided to have a go at building and fitting one of the timer kits from Maplin (Order Code:VT27E). (HUGE THANKS to everyone who contributed to those threads by the way! He would NEVER have been able to even think about doing this job without all of the helpful posts therein.)

The kit was only £6! and required very basic soldering to put it together.
The original Wiper toggle switch only has 2 positions (off-on) so he bought a new 3 position (6-pin DPDT) switch so that he could have off-Intermittent-on.
The original wiper switch basically "connects" the 2 wires from the wiper circuit together when the switch is on, so the big fella spent a couple of minutes (More like hours!!) working out how to achieve the same result from his new circuit board and switch....
Eventually, he opted to make "extensions" for the two existing wiper wires, but wired them with 2 wires each (giving 2 pairs of wiper connections - one for the wipers ON setting and one for the INTERMITTENT setting).
He wired the first pair of wiper wires directly to one side of the new switch, so that when it was moved to the ON position, the wipers came on as before.
The other set of wires from the wiper circuit were connected to the output terminals of the new timer circuit, to be activated by the circuit switching on and off.
New +12V and Earth wires were wired in to provide power for the timer circuit, with the +12V wire being connected via the other side of the new DPDT switch, so that it only gave power to the circuit when the switch was in the "Intermittent" position.
It WORKS!
The timer circuit board has 2 adjustable resistors for varying the pulse (ON) time and pause (OFF) time, so you can precisely set the length of time the wiper motor is on (so that it returns to rest after one wipe) AND you can set the gap between wipes to something sensible.
The big guy seems quite chuffed with himself (even though it turned out to be quite a simple job) and the intermittent wiper really does work great.
I'm just a bit worried now because I'm sure I heard him mumbling about my headlights not being up to scratch....
