I'm not sure which part is the innacurate part. It probably stems from years of corrosion on the multiple wire connections between the sender and the gauge, as well as the grounding of the sender. Throw in the age factor of the sender and who knows.

As far as the other MAP sensor plumbing, you would need to tie into a vacuum hose. I would probably tie in to the vacuum hose going to the control pressure regulator (WUR) so you are reading boost pressure in the manifold. It probably doesn't matter, but that would be eaisest. Just use good quality hose and a solid vacuum "T" so you won't run the risk of loosing your boost enrichment if WUR looses it's boost signal. I believe there is a plug on the rear of the original BOV assembly that is 10mmx1.0? You could also use a banjo fitting and banjo bolt from a CIS fitting and tie it in there. I probably have one lying qround somewhere
