Overboost control

On my stock 77 930 I drove it into heated dehumidified storage last fall. The fuel pumps are humming now but will not start. I noticed the boost gauge was showing some boost before I put it away when just driving normal and spiking almost to the 1.3 mark under very light throttle. My thought is the overboost sending unit is Kaput. Where is that overboost cut off sending unit located and the control unit that monitors it? I probably have spares if I knew where located and what they looked like. Thanks. All the modded ones start right up after winter storage. Contrary to popular opinion the pristine original is the one with a problem, go figure. Hate to put it on a trailer and not able to find a Porsche expert to make a house call just yet.
