OBD1 and OBD2 Manifolds

Whats the difference and how do you tell which ones fitted?

You can tell them apart by looking at the hole where the throttle body goes at the back of the manifold. OBD1 ones have a tube coming out of the manifold on the expansion tank side for the idle control gubbins. OBD2 does not as the idle is sorted by the trottle body itself.
