hey i was wondering how i put a tacho on my vn commodore. do i have to run a wire through the dash. where does the wire go. is it hard to fit one? cheers
ok...... you will have prob three wires coming out of the taco... one will go to ground(earth) the others will be for accesories and signal wire. the signal wire will run to a brown wire on the passenger side of the engine there's a loom there which has a small white plug hanging out...on the end of the plug will be a brown wire by it's self. that will give you signal.
make sure the taco is on the correct setting or you will be doing 8000rpm changes.,.hahaha
ok thanks. how do i get the wire through the dash? will i have to take out the dash or something? what side is it better on. the side right hand side of the steering wheel or the left? and na my car doesnt already have a tacho for some reason.
NOTE: The wire colors might not be the same on all Tachs.
Its pretty straight-forward installation but as for the Green Wire (refered to diagram) can be connected to the signal wire found next to the Right Strut Tower (looking at front of car) in the Engine Bay (White Connector and Brown Wire, which may be hidden under some tape). Run a new wire from the connector back through the Firewall to Tacho.
