Some of you might be interested to know where the ground distribution point is for the various sensors under the hood. Having good ground is important for the sensors to operate correctly. The good news is the TSX has very good ground connections and there is no measurable difference in supplement it with additional ground. However, if you must do it, consider this one...

Ground distribution - Note the various sensors and their ground termination point (G101).










Supported sensors & components:
- ECU
- VTEC oil pressure switch
- CKP sensor (crank shaft position)
- CMP sensor A/B (cam shaft position)
- Countershaft speed sensor
- VTC control solenoid valve
- VTEC solenoid valve
- Ignition coil 1 to 4
- Knock sensor
- Throttle actuator control module
- Transmission range switch (AT)
- A/T clutch pressure control solenoid valve A/B/C (AT)
- Mainshaft speed sensor (AT)

 

Was this one of the other installs you did on oyur day off?

Looks like you added an additional ground from the negative terminal to the top of the EGR cover?

 

No, I made the battery tie-down during my day off. I did the ground terminal this morning.

 

Just curious... why didn't you ground it to the bolt where the G101 arrow is pointing?

 

Because the bolts are mounted on the same metal plate, and the bolt on G101 is not long enough to add the terminal.

 

Can you give us more detail about this? Where can I find the wire part?
thanks Johnny,

 

You can find all the wiring hardware from any car audio shops. I used "0" guage monster cable and monster terminals.

 

so just do as what you did in the picture?
