Here's a look at the electricals of the car. It's essential a complete new system from a VR Calais. I bought new harnesses, TDM, PCM and BCM. I also needed to by the remote module that is used to run the steering wheel audio controls.
Drivers door courtesy switch installed along with a VZ door wiring harness conduit. This style of conduit is on all 4 doors.
Drivers side rear door conduit fitted.
On the right of the picture is the drivers side rear door. I mounted a Commodore door jamb switch in the door as there was no room in the pillar. It needed a bit of fiddling but now works perfectly.
Closeup of drivers door central locking motor and the simple mounting.
Billet stop light trial fitted for height mainly. It will sit too low once the window is installed. I will add some height to the parcel shelf to fix this problem.
I couldn't get the horn to work even though all the wiring was correct. I hadn't fitted the black control unit seen in the middle of the picture. This is the steering wheel remote controls control module. I didn't think I needed to fit it as I'm not using the steering wheel audio controls factory fitted to the Calais and Statesman. Without it though the horn will not work.
All the wiring in place under the dash. This will be behind the console once it's fitted. The black box on top of the PCM is a unit that operates the reverse lights from just a 10ma source used to illuminate the gear shifter display LED's
Some time was spent cleaning up the console wiring, fitting the boot to the shifter to seal it to the floor and installing the power window and front speaker harnesses.
Final wiring job was to place all the instrument, switch and control unit wiring into its final spots. There is a lot of wiring under the console as most switches live in the console. Wiring is needed in the console for the cruise control actuator, headlight switch, hazard light switch, electric window switches, trip computer control, hazard light switch, security LED, power/economy switch and the led gear shift indicator. It's a busy place but now its all in place and working.
Under bonnet electrics in and complete. Genuine Holden covers to keep it all neat
Wiring in and everything that has been tested so far is working. So it should as its a brand new Holden harness and computers.
A mass of wiring lives behind the grille to keep everything out of sight.
Firewall grommet installed and sealed with silicone for a water and fume tight seal.
Main harness under the drivers guard now installed an cable tied up to the steel frame that I made to keep the harness away from the wheel and suspension.
Underdash frame with PCM, TDM and BCM fitted. AC unit also fits to this frame in place of the original glove box.
Interior showing dash frame and pedals now fitted. Cruise control unit mounted on transmission tunnel will be inside console when its fitted.
