It is not a stupid question. Installing wiring can be confusing and it is very helpful to see a video that shows how the installation is done. Unfortunately we have not had a chance to install a Brake-Lite Relay, part # RM-88400 on a 15 Wrangler Unlimited. We try to make as many videos as possible when we have the chance.
To determine if a brake light relay is needed you can answer the following questions:
Are you using a supplemental braking system that depresses the brake pedal in your towed car?

Yes - You may need a brake light relay. Continue on to the next question.
Do the brake lights on your towed car illuminate while the engine is off?
No - You do not need a brake light relay.
Yes - You may need a brake light relay. Continue on to the next question.
Do your towed car's brake lights act as both the brake signals and the turn signals?
No - You may need a brake light relay. Continue on to the next question.
Yes - Your towed vehicle has a combined lighting system. You will need a brake light relay to ensure proper activation of its signal lights.
Does your towed car have separate brake lights and turn signals?

Yes - Your towed vehicle has a separate lighting system. You may need a brake light relay. Continue on to the next question.
Are you wiring your vehicle with a six-diode kit or a TowDaddy custom wiring harness?
No - You will need a brake light relay to ensure proper activation of your towed car's signal lights.
Yes - You do not need a brake light relay.
Most vehicles require the normally open installation. If your vehicle has a push-button start feature that will not start the engine with the brake fuse removed, you will need to perform the normally closed installation. I have attached the wiring diagrams for each of the installations.
