Default Rear signals not working

I got a used trx4 bronco with the lighting kit. I had to clean the main module on the car with contact cleaner because headlights didn't work. Now ive got the front signals to work but no rear. Is there something else in missing?

Did you install the short plug on F of the distribution block in the body?
This is what makes the rear lights blinkers too.

You can get manuals on the pro scale kit @traxxas.com, see https://traxxas.com/products/parts/6591?t=support and there are drawings and explanations.

I think the previous owner had it hooke dup wrong. From my understanding you don't use the maxx link with the Rx in. Can you use the maxx link cable without the Bluetooth? I feel like the lights are on the wrong spots on the rx

The Maxxlink is for Traxxas Rx, the servo connector for non-Traxxas Rx. Dunno if you can use both parallel, manual says "optional" on the Maxxlink but does not show servo connectors to the Proscale.
It does not have to do anything with the bluetooth Link, except that using the App to power additional lights only works with the Maxxlink.

But i see you're using the Maxxlink plug on the Rx but Rx-In on the Proscale. That's not ok, Rx-In is for the Servo wire, Maxxlink comes to the Maxxlink-In port. I can't imagine why it still reacts to the steering...
Or does it seem you have the servo wires connected to the Rx-In and another Maxxlink ending in nirvana? Maybe additional sensors or so? Can't see clearly what you have in the Rx box.
Maybe you should take a look where all the wires go and check with the manuals i linked above.

Also, on the Distribution Block are some wrongs, but most is ok:
A is used for reverse lights. Not used in your case, did you not fit them?
C (rear lights) and D (rear markers) seem ok.
G and H are for front lights, seems ok although H could need a refitting i'd say.
The short plug on F is missing, and that's what makes your rear lights work as blinkers. Without it you'll need some extra Blinkenlights plugged into another port, but that's for bodies that have them.

("Hijacking" this thread for a similar problem...)
I want to attach a bumper light bar, #8088, to the "Pro" power module. The manuals don't say where to attach it, but to consult Traxxas' support site.
Traxxas' support site only contains the manual refering to that site...

So, do I use the adapter similar to that used for the roof bar (8087)?
What output(s) (of the 10 or so available on the power module) should I use?

Found the answer to my question!
The answer was in the manual for the Pro installation kit 8083.
