== Late Van (Requires relay fitting only) ==

'''Matt:'''
go to scrapper; find vw; open glove box; pull out relay with No. 19 on it

drive home past muppets xmas shopping; put kettle on

put in fuse box into position 10 (remove metal insert)
remove plastic crap from steering column

the kettle may have just finished boiling

sit back and laff hard

buy matt a beer when you see him

Vans with wash/wipe but no intermittent wipers already have the relay, so just pull off the steering column cover and pull out the white gizmo from the switch, enabling your switch to move down a notch, and giving you intermittent wipers!

'''Fitting Intermittent wipers to an early T25'''

One thing that annoyed me on my camper was the lack of an intermittent wiper option, especially when it was spitting. [http://www.peterkay.co.uk/ | (Everybody in. It's spitting!!!!)]

I could only put the wipers on continuous and I discovered that in their wisdom VW rarely fitted the option on early vans
and even ommited them from later vans even though they installed the wiring.

Here's a guide on how to fit the option to an early T25 (mine is a 1983 model with ceramic fuses).
There is a guide to the easier method of installing it to later ''blade fuse'' models [http://www.keithandsylvia.co.uk/tech%20pages/t25_intermittent_wipers.htm For vehicles with blade fuses See:]
First job is to get down to the scrapyard and pick up relay number 321 955 531A (as in above picture). These can be found on
most 1982-90 VW's, they also have a big 19 stamped on them. I got 3 from my local scrapyard for £5.

'''IMPORTANT''' Disconnect the battery before commencing and use properly insulated crimped connectors and solder

Remove the plastic steering column surround by removing the two retaining screws underneath.

Then remove the white retaining clip as shown in the next three pictuers. This will now give you a third intermittent down position on your wiper switch arm.

Right now for the wiring. I consulted the Bentley wiring diagram (fig. 4) which shows the relay as it should be incorporated in the system. Being lazy I couldn't be bothered to wire the relay up so it fitted in the relay fuse box so i wired it up next to the wiper switch on the steering column.

After removing the wiper switch harness (figs. 5 & 6) I noticed that the terminals were marked like the above diagram.

[[Image:inter_wipe_4.jpg|frame|left]] 

And from that I came up with the following diagram of what I was going to do. (fig 7)

'''NOTE:''' Position J in the indicator switch has no connector or wire to it so you need to create one. The easiest way is to purchase a 1/8" female lucar connector as shown below. This when crimped will push into the switch plug and lock in place. Feed your wire through position J (the way it would be if it were being connected to the indicator switch), crimp the wire to the lucar then push the lucar back into the J position in the switch connector block

Fig. 8 shows the relay wired up. Now all I had to do then is secure it to the steering column and replace the steering column cover (figs 9 and 10)

Reconnect the battery and you will now have intermittent wipers that will also wipe 4 times when you activate the screen washer. '''GOOD LUCK!!!
