Apparently there is a resistor in the tach wire, there was a thread in the Corvette forum about the same issue. They changed the resistor to 4.7K ohms and then the tach worked. It seems there is pull down voltage from the ECU and if too low the tach doesn't work. Just my $0.02... \ \ The wire that I have installed is a brand new wire that goes directly from the neg side of the coil directly into the box for the dakota digital unit. Only one wire and only one install port. so pretty simple. I am going to try https://www.summitracing.com/parts/...hmpKMan0RP1rpz8RPcLVLOElGWgaAiHlEALw_wcB Contact Me about AMD Prices
