When I got my car. ('79 12a) the factory tach had been cut out and just left the hole, and aftermarket one was in there, but it is bust. I have another factory tach and was just wondering if anyone knew where the 4 wires off the back of it goto on the circuit board in the instrument cluster. Maybe a picture of the back of the cluster, showing where exactly the wires go, cos I really have no Idea.
Thanks.

 

Oh no!!!.... Some one must have a link or pic or sumthin hiding away of the circuit wiring diagrams of the instrument cluster.....puhlease?!....i hate drivin wothout a tach....its just not right not knowing what you're engines doin'.

 

Do you have a haynes manual????


I will get a pic of mine tomarrow... if I can barrow my sis's camera...


Thanx, Laterz, Andrew

 

Cheers,
Na, I havn't got a haynes for the 1st gen, I have a 2nd gen haynes.....but someone stole my 2nd gen, so its kinda useless to me now.....

 

Get a Haynes manual or wait for Andrew to post a picture. There is a nice picture of the back side of the speedo cluster as well as many wiring diagrams.

 

I guess no one found a pic then
