I think your question is for the boost gauge sending unit, the red rubber covered thing attached to the boost recirculation manifold. It can be seen directly beneath the intercooler in the center of the engine.

Here is some useful information for testing the sender. The internal resistance should increase as air pressure increases. Remove the sender and hook an ohm meter to it, then apply controlled air pressure and see if you get close to the following readings:

0.0 Bar 5 - 13 Ohms
0.9 Bar 117 - 129 Ohms
Mark H. 1987 930, GP White, Wevo shifter, Borla exhaust, stock everything else. The result of a massive Pelicanite good will fire recovery effort. Truely an open book, ready for the slippery slopes to modification.
