Need help hooking up my Classic Instruments speedo to VSS...
I'm trying to install my speedo from Classic Instruments and I'm a little confused on the VSS signal that need to go to the SN77 Speedometer Signal Interface. It appears that I need two wires for the VSS going to the SN77 Interface; sensor ground wire and input wire (VSS signal). Here's my problem, I'm trying to tap into the VSS wire (pin 68) off my PCM. It's only one wire and the SN77 Interface needs a VSS ground. Does anyone know how to wire up the SN77 Speedo Interface? Any info would be greatly appreciated ...travis
