1994 Rear Wiring Harness - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I am completely re wiring my 94 Sierra with a painless wiring harness. I removed all computer controlled components etc…

The loom under the Hood with the Taillight wires has an extra yellow wire (2 yellow wires instead of one) that goes all the way to the Taillight harness. It also has a purple wire - that does not make it back to the Taillight harness. I can’t find these in the manual. They don’t appear to be aftermarket, they are in the Factory Loom.
