Did a first start on my hot rod with 5 L Coyote yesterday. Frame is still sitting on jack stands with tire and wheels mounted. Put TKO600 trans in gear and ran the differential. Noticed my speedo is not registering. Followed the Coyote build PDF and installed speed sensor and tied it to the ECM and trans. Chassis harness speed sensor plug was not used. Not sure of the correct way to send the signal to the speedo. Do I tied the chassis harness wires in parallel with the Ford speed sensor plug? I know someone has already solved this issue. Thanks.
