Rev counter conversion

Hi,

I'm sure this has been asked a thousand times, but couldnt find the answer when I quickly searched.

Currently my 84 Doka (1.9 petrol) has a 'standard' dash. I have a chance of a T25 rev counter with the fuel & temp gauges in the bottom corner.

Whats involved in converting the existing cluster?

Thanks in advance

Changing the dash is a trivial matter. Just pop off the cover. Pull out all the switches apart from the lights light which does not need to be pulled out, its got a connector you can disconnect. Pull off the speedo cable. Pull off the 14 way connector which is reached under the dash to the right. Undo 4 screws.

Comes away as a single unit. Just put the new one in and see if it works, not all the older models have the tachy signal to the dash.

84 means you probably have the early wiring , ceramic fuses like beetles / bays?

this will mea your dash connector is vertical?

all revcounter dash's are post 86 , blade fuses and have a horizontal connector.

DO NOT connect it up.

the wires in the connector have to be moved around as they are not the same.

also you will only have 1 oil pressure switch on your engine ( factory spec) post 86 they had 2 , the 2nd works on a rpm sensor.( oil buzzer)

having a rpm sensor means the wiring for the tacho is in place , yours being early will not have this ( some imports or high spec vans do) so you will need to run a wire from the coil - to the dash

i also think from memory that without the rpm sensor the oil light does not work either . i did the conversion on my own van but that was aroud 8 years ago!

cant remember the wiring change , but it may be in the wiki somewhere.
