Sierra dash wiring

[MARTIN SQUIRES]

Hi all, 

the build wiring diagram and the loom I have don’t have corresponding colours, is there a variant of model that is different, I’m using a 1989 Sierra sapphire donor and a 2B plus kit. Anyone know a auto electrician near Manchester?

According to the Haynes manual there are/were 3 slightly different instrument clusters. The difference is small, the first ones had a single lamp for the indicator flasher, the next had a seperate lamp for right or left turn indicator and eventually a clock was added. Given the age of your donor your cluster should be the one with two turn lamps but no clock. A brief scan of all three versions indicates that the colour and purpose of the connecting wires remained the same. I am not familiar with diagram and loom that you have with you kit. The task that you (or your electrician) has is to match the wires in your loom with the function of the wires (or connectors) on the cluster connection plug. To help you do this I am attaching two diagrams, the coloured one shows which wires match which function on the cluster (by colour) and the second is more detail on which pin on the connector is related to each function. You need to identify which colour wire in your loom matches which connector/colour on your cluster.

Thank you for your help. I’ll try and figure it out.

Hi Martin, some 2Bs came with a "Vicki Green" loom.

Here's the drawing for it ............

If that's the loom you've got you should be able to work things out with the info. about the Sierra from Sparepart above.

Good luck,  Steve
