Sierra Lighting Cluster Wiring -Help

[Spikehaus]

Help,

I have spent a good few afternoons stripping back the orignal sierra loom to expose the front and rear lighting circuits for ease of fixing and simplicity in the final installation. However, I feel reasonably confident with electrics but am stuggling to match the 'The Haynes Sierra XR4x4i black & white wiring diagrams" to the installation.

Part of the issue has been caused by selling the front and rear lighting clusters a little to quickly!

What I need to do is identify which lights are in the main front cluster and the colour of the wires that connect to them.

High Beam / Low Beam
Sides
Another bulb?

Indicators and fogs? in the bumper lens

In the haynes manual the cluster is just marked 1,2,3,4,5

Guess this is a question for Twin Turbo!

Thanks in anticipation!

Will have a look at the official diagrams when I get home.

What year was the Doner?

Headlights contain -
Main & Dipped combined unit
Side
Main Beam seperte unit.

Mmmmm,

That makes sense, an additional main beam unit. Guess that was an optional extra.

If the wiring for the headlights is the same as my donor, the Haynes manual was spot on.

Left Headlight
White = Main beam +12v
Yellow = Dip beam +12v
Grey/Black = Side light +12v
Brown = Earth

Right Headlight
White = Main beam +12v
Yellow = Dip beam +12v
Brown/Green = Earth for headlight through dim/dip relay
Grey/Red = Sidelight +12v
Brown = Sidelight earth

Hope this helps.

Cheers

Thats great gus, did you have 2 nr white wires on each headlamp?

I just had the wires I listed. The wiring for the second main beam bulb was an integral part of the head lamp.

Hope this helps.

All MK2's had extra main beams,
A lot of MK1's also had them ( especialy later ones )

Not sure how different the wiring was on the MK1 for the headlights as I don't have an early set of diagrams.

Had a great day in the workshop wiring up all the lights with thanks to the help and infomation provided above. I had to replaced a few 10 A fuses for the side lights but apart from that it all works well.

It was a bit more of a demanding job sorting the hazzards, but with a bit of work with the multimeter I tracked it down to the 3 pin flasher relay. I bridged the contacts and the idicators lit up.

Spent the rest of the afternoon driving round local motor factors where I purchased a new 3 pin flasher relay for just under a tenner, so hope to fit that tomorrow and wire the reversing and fog lamp.

I think I have been quite lucky with my £150 doner with only having to replace two original relay from a "C Reg" car.

I hope to replace the wires that came factory fitted on the lights for colours to match the Sierra loom. This should simplify things when I strip down and rebuilt the car.
