tach lead

hey i just got a tach for my car and we have all the stuff we need to install it but our haynes book doesnt say which wire coming off the coil is the tach lead. You guys know?

Its a 1.5 91 DX 4 door by the way

my friend said it was the blue wire but there are 2 different sets of wires coming off of it. If it is the blue wire, which blue wire is it?

the blue wire with a silver stripe

thanks dude, we couldnt find it newhere online or nething and we didnt wanna start tapping into random wires. Thanks again.

look on back of gauge cluter. the plug on the left should have a blue wire at the edge of the connector. That is your rpm signal. I spiced into that so i didnt have to run a new wire all the way through the engine bay and dash.
