This one's probably been done to death, but the search engine on both forums is crap to say the least.. so anyway..
I have an autometer boost gauge ready to put on to my AE101 GZE, but I've hit a snag.. I have no idea where to plug the gauge in to the actual engine.. where abouts is the easiest place on this engine to put it?
find a vacuum hose (i think there is one in front of the brake booster) and splice into it with a T piece and run the guage off that. You will have to invest in some fittings and thin PVC hose in order to customise your set-up. Ensure everything is air tight and away you go.
