Hey i am trying to install a tachometer gauge and a vacuum gauge
on a 1996 honda civic and im having trouble knowing where to hook up the tube
to for vacuum and finding the ignition coil negative.

Any help

thanks

 

Tachometer connects to the blue wire at the cluster. All versions have this wire even those without factory tach.

Vacuum you can connect anywhere on the manifold I suggest teeing into the hose to the cruise control or the purge valve (the valve inbetween the canister on the firewall and the manifold, tap the manifold side).

 

Thanks!
Im not good with name for valves and stuff but would this hose be a good one to
hook it up to?

Could you do it to hose numer 18?

 

Yes 18 would work.
