I installed an HKS type 1 on my 1987 Supra but the rpm indication is reading zero. The pin its connected to at the ECM is black, I checked and there is no voltage. Should there be? Did the installation manuall gude me to the wrong spot? I triple checked and everything is connected per their instructions.
