Quick power question





I'm putting in a new engine harness (taking forever to rewire it the way I want) and have a quick question: I'm not using a TCS switch on my carb, but I wonder if the wire that connects to it is powered when the key is on? Is there switched 12V available there?
I am setting up a few relays for fans and headlights and horn and need a good switched power signal.
If it's not, can you suggest another wire that I could use, preferably from the same harness, since I already have it out!!
This is not the "headlight harness", but the other half of the bulkhead connector, the "engine harness".
Thanks for your help!





Besides, I'd like to stay in the engine compartment if possible.
