hey guys, car is 1991 Civic Si, SiR guage cluster, B16A1 w/Y1 tranny. has factory VSS. my question is: there are three wires coming off the VSS. yellow, blue, black. where to they go? I THOUGHT the yellow was to the cluster (have wire attached and waiting for connection at cluster) one was to ECU and one was ground...but I saw something that makes me think otherwise. anyone have any idea?

thanks!!
