Ok so I have just bought this VDO clock for a few pounds:



I need to know how to wire it up, you'll all know I that I know nothing about wiring after my recent new head unit install - but we got there in the end! This is the last thing to be wired!

The inscription along the side reads:

477 919 211
218/28/1

This is the back:



Ok so,



this is what I think - am I right?

1) Power (guessing a 12v wire)

2) Earth

3) Bulb

Now what do I wire to where and with what type of cable?

This is a close up of 3 when the bulb is removed with the spade connector on the end.



Ok so that is lots of photos and the inscription on the clock, guessing that is enough to keep you going for the time being! Sorry about quality of photos but the camera is still bust so relying on my Palm.

from what i can work out from the pics you are correct:

1. live
2. earth for clock and bulb.
3. bulb

you will need to wire (1. live) to a permanent live, then (2. earth) to somewhere on the body or the - on the battery, then (3 bulb) to the light circuit.

Couple of short lengths of wire (preferably some purple, some black and some red, 5 amp should be fine) from Halfords and some crimp spades and a crimp ring terminal. Clock terminal #1 to fuse box terminal #4 (purple existing wiring, use purple cable), clock terminal #3 to fusebox terminal #8 (red/green existing wires, use red cable preferably). Clock terminal #2 using black cable and a ring terminal to earth under any convenient screwhead behind the dash or the main dash earth if you can reach it. Easy. The clock will draw a negligeable amount of power so it's fine to wire it into the existing fuses and use them to protect the circuit. Using the terminals I have listed will ensure the clock is wired using the fuses. I am assuming you have a 4 fuse fusebox car at the moment just because it is the most common and you haven't said what you have. If your car is different ask again.

Simple!

Excellent - thanks for the help. All sounds straightforward except the purple live wiring. I do have the 4 fusebox fitted on my 1991 Rover Mini. On position 4 I have the existing purple wire going into one spade and have my headunit going into the other, so there is no free permanent live position. What does the existing purple wire actually do?

How do I get round this to get the clock wired up?

Thanks again advance...

It runs everything in the car that works independantly of the ignition switch, except for the main lighting. Brake fluid warning, horn, headlamp flash and radio memory for cars fitted as standard with radios that need it. Your car should have a radio connector in the harness that already supplies this so you shouldn't need to connect an extra feed for the radio to the fusebox but since you already have done you may as well leave it. You need to use a piggyback spade on the clock wiring (if you can find one) or crimp both the stereo memory wire and clock wire into the same spade terminal, joining them together.

Cheers Dan for your help, wired it up with a piggyback connector from the fuse and it is working a treat.
