Can Rain sensor wipers be retrofitted easily?

Our 93ss gets it right most of the time, they are set to 'medium' sensitivity and I've not neede to change it.

I have as much trouble with the 9-5 choosing 1 of the 3 intermitent settings and waiting for the next sweep for that setting to take effect.

Like voice control, the ford system in my transit is spot on and it only struggles when I drive fast so the noise in the cab is quite high. I have a friend with a Merc and the voice control in that is rubbish, its been back several times and the dealer reckons it struggles with English 

I have orderd one of those kits so I will see what it looks like when it turns up. Anybody got a schematic of the wiring of a 2002 Aero so I can see if I can break into the system when I come to fit it, my thought was to put the wires from the control unit in where the Intermittent relay goes so not having to cut any wires if possible? Where is the relay for the wipers?

There are two wiper/washer systems.  It's difficult to say when they changed from one to the other, but I think it was mid-2003.  But I can't be sure.

All the relays are in the box by the battery.  List of fuses and relays is in the lid.

The wiper motor is fed from Fuse 37 in the fuse box at the end of the dashboard.

The kit has arrived.



Looks OK but might be a complicated job to wire in.



I am hoping if I can work it out I can connect it to where the relays are, hopefully I can remove the existing relay and connect this box in instead. This way if it does go wrong I can pop the old relay back in and be back to where I was.

Anybody got a copy of a 2002 wiper wiring diagram I can use?

Good luck Steve - you're a brave man!

Let us know how it goes and how many days it took to work it out

The difficulty is coping with DICE. For that reason I wouldn't recommend cutting any wires.

A brief description:

The motor current is switched via the wiper stalk. However the intermittent wipe and single wipe after wash signals are generated by DICE, which doesn't have the capability to sink the required current, so drives the intermittent wipe relay instead.

The suggestion of removing this relay makes sense. I would think it might work just by connecting the yellow wire of the controller to pin 3 of the relay base, and not bothering with the white or green. You'll need to connect the brown, red, grey and black as per diagram.
