Tach wire up questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have the brown wire from the tach harness going out through the firewall and it is connected to the spade on the left side on the hei distributor. The Hot Lead black wire is connected to the side closest to the firewall, which is the right side .

I have this pink wire inside the cab that is part of the tach harness that has two connectors on it and I need to know what they hook up to and where .

I understand that the two prong end with the pink and brown wire goes to the tach .
I was wondering if this is universal harness and was made for more than one applicaton ? Pic below . gp
