I recently purchased one of the 3 gauge packs from an e-bay seller. The gauges consist of an absolute pressure gauge, an oil pressure (5 Bar) gauge, and a voltmeter. I installed a vacuum tee in the vacuum hose that supplies the cruise control servo, and it works well (at least at showing a vacuum since there is no power adder to make any manifold pressure). The voltmeter works well too. I know that I need a different oil pressure sending unit, and am about to order one from the high priced web site. I am ordering a sender with the 85 psig rating, and the idiot light/gauge option. My question deals with the wiring for the oil gauge. The factory harness for the gauge package was complete, so it's a plug and play affair for the gauge lighting, and since I already had a single voltmeter installed, it was an unplug/replug thing too. It seems as though the blue/red wire is battery voltage, and since the oil pressure gauge has no sending unit signal,it is pegged (I actually unplugged the harness from the gauge to minimize damage to the movement). It looks like there will only be one wire that needs to be added, and that would be from the sending unit to the gauge. Is this correct?

If anyone needs a single mount voltmeter, and a single mount oil pressure gauge, both with the rubber feet, and the finish bezels let me know. They go to the right of the instrument cluster, where the small clock normally is found. I also have a very nice knick-knack tray that goes above the center A/C vents (where the 3 gauge pack now resides).
