ok well i installed a triple gauge pod, i have volt, airfuel, boost/vacuum. i have connected the volt meter, that works fine. however im stuck on how to connect the a/f and b/v gauge. i was thinking to hook up the a/f off the o2 sensor but there are 4wires and have no idea where they go. the b/v gauge was going to find a vacuum line but lol there isnt a diagram for the lines so im confused. if anyone could help me out id be appricated. thanks

 

tap the boost gauge off on the brake booster line thats running along the firewall and bout halfway turns into metal. tap it on the right side of that to get a more accurate reading. volt?? imo shoulda got oil press. or temp.

 

is the car boosted? what kind of A/F gauge are you using? wideband or narrowband? Either way, you won't be able to use either of them unless you are using a wideband sensor with a wideband gauge. The tC comes stock with a hybrid 02 sensor that reads up to 3V's, and neither sensor accurate reads 3V.
