ok so I got the trans temp and exhaust gas tempature gauges hooked up. But where do I hook up the boost gauge line. I cant figure out or find where the supplied vaccum line from the gauge needs to go.
here is a link for a 7.3 i know yours is a 97 but i hope it helps...on my 05 it tapped into the intake elbow...havent worked on a truck older than a 99 but prolly pretty close to the same idea
