Hi all, i have a 79 datusn sunny and it has the econo-monitor gauge option. Which i can find next to no information on.

All i have gathered is that:

It the little thing hangig off the wiper motor, and has a vacuum hose running to the manifold.

It lights up green when in low revs, but red in high revs.

my biggest question is where the vacuum hose connects to the manifold. i cannot see any fittings that suit the hose.

If anyone has ANY info it would be greatly appreciated.

thanks.
