Setting up with an existing bitcoin full-node

[CCGLLC-knc]

I already have an existing bitcoin full-node running. I've setup the following in its .conf file:

listen=1
whitelist=127.0.0.1
txindex=1
addressindex=1
timestampindex=1
spentindex=1
rpcallowip=127.0.0.1
rpcuser=bitcoin
rpcpassword=SomewhatRandomStuffkl;asdfjklp[oklsad
rpcworkqueue=64
zmqpubrawtx=tcp://127.0.0.1:28332
zmqpubhashblock=tcp://127.0.0.1:28332

And I've had the local bitcoin node reindex for everything.

How can I point insight, that is running on the same machine, to use this node?

For what its worth: the default startup appears to be running fine for internal use (I have the port blocked at my firewall):
