I need some help with installation of autometer gages for oil pressure and voltmeter to be installed in sos pillar. How do you wire the gages and lighting. Where is the location to install the oil pressure sending unit??

 

Anybody installed autometer electric oil pressure gauge on 07 GT?? Where do you install the oil pressure sending unit-my car didn't come with an oil pressure gage. Also would appreciate any help with the wiring of the oil pressure gauge and the lighting for the same. What color wires do you tap into for the lighting circuit and where do you tap into the wiring for a switched power source that Autometer recommends for the oil pressure gauge??I am installing the gauge in a SOS pillar and want to install as neatly as possible, really would appreciate the help!
Thanks Gstang
