I just got my Tach and Air fuel ratio gauges from Ebay. And I think I have them hooked up wrong. The tach works perfect from idle to 2500 rpm but will not go past
3000 rpm. I hooked the signal wire from the tach to the black wire with a white stripe on the coil. Should it go the other wire on the coil? I think it was green with a Orange stripe.

The A/F guage I hooked up to the grey wire on the o2 sensor . The one before the cat. and the guage stays pegged on LEAN. Should I hook it up the the O2 sensor
after the Cat?

Thanks for the Help!

Well I mashed the long pedal on the right and got the tach up to 4000 rpm seems a little low but maybe its working.

I think I have the A/F gauge hooked up to the ground instead or the signal wire . I will mess with that later.
