Is there anyway to keep my current in dash gauges working while installing new mechanical gauges? I ask cause a friend took his heep to the emissions test and they had a fit cause his factory gauge didn't work. They wouldn't even test it :doh0715: I don't need that hassle. I'm planning on adding a oil pressure, water temp, volt meter, and tranny temp gauge. The only factory stuff I'm really worried about are the oil pressure and water temp...any thoughts??
