So my friend gave me his Pivot Tachometer but he doesent remember how to wire it back up to a Integra....also It didnt come with any instructions.. all I know is that it has 4 wires...White / Black / Red / ORange .... I believe Black is Ground and Red is to a 12v source... but where do i hook up the other two wires???

Pix will be helpful.....Thanks in Advance

 

All wires can be hooked up to wires behind the gauge cluster.

<u>Tachometer Wire ---&gt; Cluster Harness Wire</u>
Black ---&gt; Black (or dash bolt) [ground]
White ---&gt; Red/Black [illumination]
Red ---&gt; Black/Yellow [12v]
Orange ---&gt; Blue [signal]

 

ok kool... thanks

 

for the BLUE "signal" wire.... do i tap it to the harness that only has 3 wires? (farthest yellow harness to the right if you were facing the gauge cluster)
