I got a mechanical Auto meter boost/vacum gauge for my radix. It came with a T fitting to splice into a vacum/boost line. I am not sure which line to tap into. Does anyone have a pic of there radix setup?

 

Theres a hose barb stickin "UP" all the way at the back, by the firewall, lookin at it from the drivers side. a little hard to get to, but it's workin fine. there, you get boost and vacuum. if you go by the TB you only get vacuum. I don't know of anywhere you can "T" off of for a source.

 

I guess it is the one with the black rubber cap, not the brass fitting.

Yep, It's like a 1/8 hose barb.....

 

On my '03 the barb fitting that you show in your picture is where you get the vac/boost for the fuel pressure regulator. Using the "T" in that line (from the barb to the regulator) to get your boost pressure reading on a gage...

Thanks for the help guys. I am going to try to install it later today.

 

everyone above is correct.
