Installing Tachometer and A/F Gauge

[MXD]

Hey everyone, im trying to install a autometer tach and A/F ratio gauge into my 1990 Talon TSI, and i was wondering which wires on the COIL and on the OXYGEN sensors do i splice into to get my signal. Most importantly the tach. Thanks everyone

not really sure... i would look at the vfaqs.com for a guide on installing the a/f gauge...

and why are you installing a tach? doesnt the stock one work?

Because its a custom dash, no factory cluster. Does anyone else know?? Thanks

You have a choice of signals for the tach. You can use the factory tach signal on pin 109 or pull from one of the CAS signals. Either the TDC or crank angle. Again the VFAQ.com site has the ECU pinouts including the O2 sensor.
