Hello guys!

I got a sierra mk1 2.0 pinto engine.
The car didn't had rev counter when new, i bought some dials from a sierra mk2, i got all wires worked out and everything works except the rev counter, i know the 2 green wires that came from the plug of the dials are for the rev counter but where do i connect them? I know they sould be in the alternator but where? Which cable or terminal? Do i need to change the alternator?

 

no1? :s

 

it comes from the coil mate

it's only an extra wire

 

Hello doj. The two green wires i got from the Counter i connect one to the + of the coil and the other to the -?
