Headlamps
Wired up according to the GBS instruction sheet - tested, side/dip/full beam all working.
Wiper motor
Working dual speed - its parking on the wrong side (offside) currently so I'll need to change that - the wiper motor (or at least the gearboxes) will be coming off before IVA anyway. My wiper arms are designed to park on the passenger side.
Washer pump
Checked - working fine.
Indicators
Not really checked, but I wired in the flasher relay and mounted it under the dash.
Fuel pumps
Both pumps running now when the ignition is turned to its second click & with a little more fuel in the system they are both running quietly, i.e. full of fuel, which is a good sign
So all good news & the only niggle is the wiper motor parking on the wrong side.
