There are two kits available, depending on your year of bus. See the links at the bottom. I have a cross over, so have the early wipers and switch on the dashboard. This has always been a right pain when the UK does its usual not quite full downpour but useless drizzle meaning that I have to keep reaching forward and flicking the switch every few seconds (Matron!) I had tried a universal kit that promised to do the job, but it burnt itself out on first try. Then I came across a kit on eBay that was specially designed for an early setup. It connects in line and adds intermittent to the slow speed. Starting at 8 second delay, you can flick the switch to fast and back to slow and it changes the timing to 5 seconds, then 3 seconds and lastly normal slow. You can lengthen the timing by flicking the switch to off then back to slow so reversing the timing from 3 secs > 5secs > 8 secs. The kit works out at about £100 from the States including postage and came with all the correct connections and also some tie wraps and heat shrink tubing. Instructions where clear and I had it fitted in about an hour. It worked first time and as usual this time of year I didn't have to wait long before a full wet test. It worked well and I am really pleased. Don't know about longevity as it has only been fitted a couple of weeks.

I had looked at these a couple of years ago, the USA market use them for upgrades on their classic cars. I decided against it as I thought that unless the rain was pretty constant you would still need to keep leaning forward to adjust the timing. It is a bit of a faff though. I know Snotty has posted a good solution in the past , Got the relay ( I think) but then never got round to completing the task…..which was/is probably beyond me anyway ! Think his solution was a lot less than £100
I liked this kit, because there was no faffing about. It came sealed from damp, had all the correct connections and worked first time. I find that most of the time I needed intermittent because for some reason it never seems to fully rain whenever I use the bus Sent from my AC2003 using Tapatalk
Use to have one of these on my old TR6 https://quasarelectronics.co.uk/Item/quasar-kit-8093-intermittent-windscreen-wiper-controller or a fancy version https://www.smart-screen.co.uk/ Or make your own with a timer relay
