just installed an autometer boost guage from my totalled 300zx turbo into my 95sc. supercharger gets 5 psi max boost, (hey, better than no boost). I ported into a vacuum line that inserts into the manifold just to the center of the oil dipstick, using a npt connector. just remember to rehook the vacuum hose up to the 3rd npt oriface or ch engine light will eventually come on for vacuum leak. had to temp. unbolt a brace to thread the npt fitting in.
My 96 with 75k miles gets 6psi with same guage. Have the guage mounted to the left A pillar. My scanguage II does not register boost for some reason, but its otherwise great. 186 degrees f for eng operating temp. Trans. od always kicks in at 137. Avg and instan. mpg, rpm, intake air temp, are my usual settings but lots of others avail. Believe van must be 95 or newer, obd 2 for scanguage. Thief went thru many cars in my area at night looking for cash. Didnt take the scanguage or a sony tv i had in the back.!

Nice, can you take pics?

I know Lextreme put a video on youtube, but I'm not that mechanical when it comes to electronics.

the scan gauge will not show boost if there is no sensor to the ECU for boost or if the ECU does not output this data... the ECU in the previa is very basic for early OBD2, so don't expect anything!

guage illumination wires were tapped into the driver viser mirror light wires where the visor mounts, LE only, my 96 DX doesnt have drivers viser mirror or wires there.
