K-Harness location
Tried the search feature, don't know whats up with that, but basically gives me everything but what I am searching.Thanks in advance for the help, I know someone can tell me what I need to know.......................Dave
Follow the connector that comes from the actuator and if it leads to the left to a relay, that is the Harness K relay.
If there is nothing between where the actuator connects to the main wiring harness under the column, like the CLB instructions probably show, then you never had a Harness K kit installed.
Are you sure you had the recall done where the dealer would remove the lockplate and install the Harness K kit? Does you actuator still cycle when you turn the key, but the column does not lock? These are indicators that you do have a Harness K kit installed.
Yes, the Harness K relay must be removed before you install the CLB since the relays perform the same function. Since the Harness K relay also connects to the actuator, the connector will match the CLB, so it is possible to connect the CLB to the Harness K instead of the main wiring harness where it is designed to connect. Note, the CLB leaves the actuator disconnected, and the GM version keeps the actuator in the circuit. More than you probably wanted to know.....

Here is a picture of the kit. You can see the smaller plate in the bag.
The newer relays may be white.

Thanks for all the help.................................... ...............Dave
Update - finished the install following the input from fellow Corvette owner. Which was that about 35% of the recalls for the Column Lock didn't install a K-Harness. This was my case. So I just plugged in the CLB and started the car. The message appeared for Column Lock and I just reset it. Hasn't come back and car runs fine.
