Land Rover Discovery 1 Analogue Clock

Parts Required:
You will need to have an original Range Rover Classic analogue clock.
I used part YFB 100 410 - black face although I believe YFB 100 460 - green face is the same physical size.
Optional: For the "With glass" version, source a 50mm x 1mm clear acrylic or glass disc. These are readily available on ebay.

Dismantle The New Clock:
Take the range rover clock apart - The clear cover and clock surround should unclip, then two screws on the back of the white housing release the whole clock movement. You might need to pull the bulb from the back or wiggle the clock to pull this out the front.
With the clock taken apart, keep the movement, the hands and face, along with the time-setting button. 

Removing The Old Clock:
Check how to remove the original Discovery digital clock and hazard button panel. I used two "bank" cards top and bottom of the panel to release the 4 latches, then the whole thing slides forwards. Squeeze the hazard connector to releaseit. Pull the clock plug from the back.

Printing:
There's now two versions!
The "Without Glass" version holds the clock with an open face and include 3 pieces.
The "With Glass"  version needs a 50mm diameter x 1mm thick piece of clear acrylic or glass, held in place by an internal ring, so is 4 pieces.
You should be able to print all new parts orientated as supplied with the flattest sides on the build plate and without supports. I used black PETG (from JAYO). Total material use is about 50g.

Assembly:

1. The new clock movement will fit into the "Clock Holder". This will attach with the two screws in the back, the same as the original part. Check that the bulb is intact or replace it. Refit the bulb in it's holder. 

2. Push the Clock Holder into the "Frame Back" so the front of the clock faces up the right way in the flat side of the frame. It fill push back with about 6mm protruding. The top of the frame is with the hole for the Hazards button in the upper right. The time setting button of the clock will be bottom-left.

3. Fit the time-setting button back into the clock.

4. With Glass version only - Put the clear 50mm diameter disc into the "Frame Front", then insert the "Frame Front Plug", narrowest edge first to hold the glass in position.

5. Slide the "Frame Front" over the button so the 4 prongs slide into the frame back. It's intentionally a tight fit and should click when fully pressed in. You might need to carefully squeeze the parts together.

6. Optional: Transfer the Land Rover badge from the original clock to your new one. 

7. Transfer the Hazard Lights button from the old clock to the new one.

Electrical Connection to Analogue Clock:
Verify this before wiring up and don't let the live 12v touch ground else you might be replacing the fuse too. I checked the pin assignments before beginning but here they are from a Land Rover Discovery 1 normally:

Pin 30 PINK: Battery Live / Permanent +12V
Pin 15 GREEN: Ignition Live / Switched +12V
Pin 58 RED: Sidelights / Instrument Illumination Logic Dimmer
Pin 31 BLACK: Earth / Ground

I wired up three cables with a spade connector one end each, and a 2mm ferrule on the other. The ferrules will push into the original harness on the car. I put insulating covers over the spades to prevent them from touching during assembly.

1. Connect the bottom horizontal silver terminal on the clock to Pin 30 (Pink)

2. Connect the lower vertical brass terminal on the clock to Pin 31 (Black)

3. Connect the bulb terminal on the clock to Pin 58 (Red)

Wrap or heat shrink the ferrules in the harness to make sure they don't fall out, but they should be quite tight.

Fitting The New Clock:
Plug the hazard button into the harness. Now push the new frame straight into the dashboard. It'll push home all the way flush to the dash and click into the 4 latches, the same as the original part.
