ECM connector help me
#4
FSM says 20 is for "Combination Meter (Speedometer, Fuel Gauge)". However, it's also connected to the ABS Actuator and TCM, which have their own pin connections.
See schematic on EC-28.
Btw, I'm no wiring guru, just reading off the FSM for you.

hmmmm
The vehicle speed sensor signal is sent from ABS actuator and
electric unit or ABS/TCS control unit to combination meter. The
combination meter then sends a signal to the ECM.
funny thing is on EC 142 there is no pin 20..... also EC146 says #68 is Vehicle speed sensor and from EC28 u can see that the wire 20 and 68 both come from the comb meter, which is hooked up to ABS actuator.
EC675--- ECM receives vehicle speed signals via two different lines, and
detects vehicle speed for ASCD control.
Vehicle speed signals are input from combination meter and TCM
separately.
Signal from TCM is sent via CAN communication line.
Refer to EC-53 for ASCD functions.
sooo refer to EC 442 there is only one wire gong to ECU thats #68 no #20 like on page ec 28 SOOOOOOOO ec 28 is wrong???
do you have a wire in #20 on the ecu plug???
edit i seen u said u do , so do u have a wire at # 68?? also? they might be going to the same plug , or intercept into the same wire. IDKKKKKK ill assume i dont have #68
BTW is ur harness and ecu US SPEC?????
