Sorry completely forgot..... The ecu is a plain to get at in ZR its behind the heater box. One opened looks like this....
The relays are as follows starting from the left....
1. Rear fogs/horn
2. Screen washers pumps
3. Drivers window
4. Intermediate wiper/ door deadlocking
5. Centre locking
Its just a case of desoldering the relays from the rear (I use desoldered braid from maplins)
Relays are available from Technozen's shop on ebay
