Wiring help
 

Good day. My friend helped with an engine swap last month. While the engine was out, we painted under the hood. So everything got disconnected.
Most of it makes sense. But I have a loom coming out of the firewall above the main firebox harness, with a heavy red, a black, and a bundle of a blue, green/white and a brown/white with a connector.
I have no idea where this came from. Have a wiring diagram but can’t find this combination.
Any guidance would be appreciated.

That might be TCS wiring. Take a look at this thread:

You rock!!
That must be it.
And being as I didn’t keep the carb, intake etc, nowhere to plug it in.
Thank you.
I thought I was losing my mind.
Didn’t have that on my 69.
