I'm trying to connect my DIY Wide-Band O2 kit and need help with this:

"The Positive battery connection wire that should be connected to a switched point on the vehicle that is activated when the ignition is turned on. The other wire connects to the vehicle's ground, and preferably as close to the battery, or ECM as possible."

So what would be a "switched point" on the vehicle where I can connect this power lead?

 

wheres the info for making a DIY-WB?

You could tap into into the power and ground wires off the ecu. What car? I can look up the pins for you.

 

Cool.
