Boost gauge line

Any help is appreciated I just can’t seem to find where to tap in a boost gauge line. 02 Tacoma 3.4 s/c 2nd gen black. I seen somewhere I could T into the back of the s/c but couldn’t find out if it was passenger side or driver. I also seen somewhere that you had to tap in after the blowers so into the lower manifold but can’t seem to find how to do that neither.

 

Just run a T off the vacuum line coming off the top nibble off the back of the supercharger.

the link below will be a good reference for you going forward

Any way you could get a pic of nipple on the s/c? I don’t know which one is the vacuum line. I checked out that thread you linked but it goes deep I don’t know where I would have to look. Or I think there’s only two nipples on the back of the s/c do you know if it’s passenger or driver

 

The vacuum line for the fuel pressure regulator is what you want. Just put a T on that line.
