(See O EM vehicle sch ematic for more info)
Note B: For Speedo meters or tac hometers with a single signal inp ut
terminal, eith er one of the two signal output lines from the EC M can b e
used. Leave the remaining line discon nected. Do not con nect to groun d.
Note A:Wires twisted one twist per 25mm.
Note E: The ECM sp eedometer an d tacho meter outpu t signal line
voltages are zero-cros sin g square waves. The sp eedometer signals at J1-
37 and J1-36 are com plements o f each other. The tacho meter sign als at
J1-38 and J1-39 are c omplem ents o f each other. Maximu m sign al
