okay...right now i'm installing a tach into a 97 civic dx

does n e one have pix to help me, im not sure which wires to use...

is it the top center??

thanks

 

top center? whas that? you could route the signal wire to the distributor connections. or splice into ecu harness, or back of gauge cluster, but i chose the dist. i think it's the blue wire. then just connect red to power and black to ground.
