Caspers Knock Gauge

[buickgn3291]

Bought a caspers knock gauge. Where do i plug in the data wire, it says b7 on the ecm. Do i wire it into the connector where i plug in my ecm on the passenger side kick trim?

You don't want to connect directly to the ECM, or it the computer won't get knock data.

Instead, "T" off the knock sensor wire in the engine compartment.

There are diagrams on the site to show you where it is if you don't already know.
