Wiring Harness Pass Through Firewall

[GMT400KING]

Looking for insight and tips to best take apart this pass through with the factory epoxy that holds it together. So that I can remove/install wires without breaking it? If anyone has experience with this let me know. Thanks

I’m not a member and cannot view the pictures, but apparently the solution was discussed here regarding a 99 Tahoe:

And another one which makes it sound like it is pulled through the firewall into the cab.

Since this thread was revived, in response to the OP's question:

It can be disassembled. Use a heat gun to soften the adhesive and it can then be pried apart using the appropriate tool. Have done it myself.
