You cut the vac line between the T under the snout and the MAP, then add a T. Connect the two lines you cut, along with the boost line.


You connect the A/F to the rear 02 sensor, but no need to connect it unless you like watching the needle bounce back and forth from lean to rich. It is a pain to get the boost line through the firewall, but no drilling needed, there is a grommet under the brake booster on the driver side.
