i have an aftermarket tach, with a shift light, and i wanna put it in my truck...and also an air/fuel gauge.

which wires do i splice into to get the A/F ratio and the RPM Signal??

i got a cluster w/ a tach, but my friend has a 5spd and his cluster doesnt have a tach, so im gonna trade him mine and have his w/out a tach and install my aftermarket tach. cuz ima nice guy =P

just curious what wires i need to 'T' into to get the RPM signal and A/F ratio. for the A/F do i just splice into the o2 sensor wire on the exhaust manifold??

thanks guys!!! woot rich!
