View Full Version : tacho signal

20-06-2010, 12:12 AM
Hi all,

I have been spending the day fitting a clifford concept 650 to my 2002 arosa however I have come across a hurdle.

I have got everything working except I have one wire left that goes to the tacho signal wire that monitors the engine speed for blackjax and door locking when moving.

Does anybody here know what wire in particular this is? I assume it goes to one of the conncetor blocks behind the speedo but which wire is it?

Many Thanks

I drove a 1.0L auto once, unreal!

My information says that the rpm pulse comes from the ECU to the dash at pin 11 of the 32 pin blue plug on a very thin (0.35-mm) green wire.

I take it that would be the blue connector behind the speedo setup. Theres two connectors there but not sure theres 32 pins


any ideas?
