Question about an HEI conversion engine harness, 69, SBC, auto - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I've had an HEI on my truck for a long time. I decided to clean up the engine and underdash wiring a bit and have plans to install a new factory style engine harness. I bought one with a built in 12v feed for the HEI. My question is, about 8-10 inches downstream where the plug for the HEI exits the harness, there is another single plug female terminal from the same 12v feed (pink wire). What is the intended purpose for this additional 12v feed? I assume I simply won't need it and can ignore it, but I just don' know why it is there. The 12v feed comes from the main bulkhead at the fuse panel so this additional plug isn't for feeding the 12v into the system.
