I have two wires I can’t remember the home for.

on my carb’d thunderbolt ignition engine. 454

one black wire out of the bottom of the dizzy ( pictured )

one orangish colored wire leaving the thunderbolt box where does it live?

thanks guys!!

Part number on the thunderbolt box is 5k27A v8 HP

Also trying to figure these out my dummy self didn’t take photos of them before they came off…. Why the difference and which wire goes where as I only have 2 wires in each engine harness one is light blue other is brown with maybe a white stripe…

big sender is for oil pressure gauge,light blue wire,other sender is low oil pressure warning and gets tan or tan/blue stripe wire.

yup^^^

note below, also tan/blue wires are for audio warning.

That does not look like any TBIV connector I remember.

You will have to figure out colors from the positions in the plug. I'll see if I can find one to post a picture of.

The top one also has a temp sender. Generally not a great idea to hang all that stuff on a nipple. They have a tendency to crack.

those blue connectors need to be shrunk for them to work they are heat shrink and shrinking makes the watertight seal

ok,someone at some time changed the wire colors of that connector.
the yellow wire is ground
blue is tach or - on coil
tan wire in center is coil +
