I have a 69 Camaro with TBI set up from a 87 chevy pick-up. I'm using a 1227747 ECM. I installed a VSS sensor that installs between the transmission and speedometer cable. I have no need for RWAL or an electronic speedometer. Do I need to use A DRAC if I am only using the speed signal for ECM feedback? If not, how should I wire it into the ECM?
