Im trying to figure out where I can tap the boost guage for my alky kit. I already have a boost guage and ebc hooked up so im not sure if its ok to put another plastic T together with those tubes. The instructions tells me to find the boost guage line under the dash... where is it located?

 

Instructions assume you have a boost gauge, just tap out of that one.

Its not going to hurt anything to "T" off of your existing boost gauge line.

 

near the stock boost gauge
