Turn signal problem
This car! It had a weird problem where using the turn indicator going right the front would blink correctly but instead of the right rear indicator blinking the left rear would blink. I dropped the rear fascia below the tail lights and identified the blue/ white stripe lead with the blue/ purple stripe leads for the rear turn signals. I figured I can't tear apart this car at this late date so I cut and soldered the b/w to the b/p and vice versa. The signals work like they're supposed to but blink fast like there's an open or a bad bulb. I'm wondering if there's another lead or two I need to connect so I don't get a failure msg on the dash. The amber flash in the end tail light is what is indicated when operating the turn signal.
Is there a C7 rear light wiring schematic available to trace any wiring I'm overlooking?

Thank you for providing that info. It is just what I needed. I figured I was in analog mode fixing this car and I needed to get in digital mode. The original prob was prob a cross between the rear harness plug and the BCM but I wasn't going to tear the car apart since it was being shipped to a new owner. I had already flopped the turn signal leads but I needed to swap the matching tail light leads as well. I spliced/ soldered and heat shrinked the white/ black stripe lead with the white/ violet stripe lead and vice versa to get the turn signals working correctly without an error msg relayed on the dash. All the lights now work like they're supposed to and it will be safe with the correct indicators.
