Firstly, the intermittant wipers are set to a fixed timing. According to the wiring diagram there's a trimpot within the combination switch, so I pulled it out and took it apart... only to find I have to desolder a couple of spots on the circuit board to get the cover and switch assy off. Has anyone looked inside this? I've misplaced my soldering iron so I won't be able to go any further today.
Second is the power windows system. Looking at the drawings I've found the relay that allows the windows to operate only when the key is set to ON. However this relay controls other things so I'm a bit hesitant to wire it on permanently, I was thinking of separating the window wiring and having that on the hot bus, as long as the window system doesn't draw standby power.
Also with the windows I want to have a single switch that puts all windows up or down simultaneously, but to do that I need to know how the driver's window does it - is it set up with limit switches, or does it sense the load on the motor and shut off when it goes over a preset level? The wiring diagram only has a box thing between the auto up and auto down mode and the rest of the switch modes. I'm going to pull that area apart and see if I can duplicate the circuit for all four windows.
On my keyless entry system, the indicators don't flash when the doors are locked and unlocked - and it's supposed to happen. So I'm going to have a look at that, there's two pins of one of the immobiliser box connectors that go to the indicator box.
I also want to make the fog lights work with the main light switch set to off. I tend to use them as daytime driving lights, but to turn them on you have to have the main light switch on, which dims the aircon display and other things, which annoys me.

Once I find my long lost soldering iron, I can start getting into it further, but until then has anyone else fiddled with these things?
