Instrument cluster trouble! July 23, 2021, 09:33:19 AM Hi all, I have recently purchased a mk2 1.8 8v 1990 which I bought as a project knowing there was small issues. The speedo, Rev Counter, and Temp Gauge is not working. I have traced the coil wires (red & black) back to the fuse box where a lot of wires have been cut I have read online about the pinning etc. I have got the Rev counter to work but now the oil pressure light is flashing with the annoying buzzer noise. I know I don't have a pressure problem so thinking I have pulled the wire to the wrong place on the pin (PIN12). On top of this the speedo is not working correctly, I have changed the cable (twice) and have also changed the worm gear in gear box as mine was not the best. Now my clocks are working but are flickering and making a clicking noise. I cut the end off the old cable which was snapped and put into a drill and the clock still flickers. Can someone tell me the actual pinning sequence for the instrument cluster (number to colour and where they go) and also if the speedo issue is common? if so has anyone got a speedo for sale I have spare for the whole cluster but no spare speedo. Thanks in advance.

Reply #1 – July 23, 2021, 01:00:46 PM Point to note, being a 1990 your car could be cross over from CE1 to CE2 (CE=Central Electrics) If your hazard switch is a rocker switch on the dash panel you have CE1 if the hazard switch is a push button on top of the steering column you have CE2.The instrument cluster is different across these. 2 plugs for CE 1 and 1 plug for CE2, another way to tell is the temp warning LED is in the gauge on CE1, but is in the central LED row on CE2.There's also 2 brands, VDO and Motometer, so ideally you want to replacement Speedo to match your existing cluster. They are interchangeable but dosen't look right when mix and match.I do have a couple of old CE1 clusters and a selection of old parts including loose Speedos, I'm afraid I don't have any CE2 spares if that's what you have.With regards to the cable, the fit on the back of the speedo is very tight and sometimes it doesn't always click into place so would give the issue you report. But if you've run it on a drill then I guess the issue is within the speedo itself.
Re: Instrument cluster trouble! Reply #2 – July 24, 2021, 08:43:35 AM Thanks for the quick response. Min looks to be the ce2, hazzard below the sluster on a push button and single plug. I managed to get a spare set of clocks as I thought they were instantly the problem ( for a bargain £20) but the clip on for the Speedo had snapped which looks like the only part I need haha. I will find a new Speedo and put that in the old cluster hopefully this will fix the problem. Any idea on the oil pressure warding etc? I have had to run a new wire to the fuse board for the rev counter to work as I only have two wires on the coil from purchase? Cheers
