Video Transcript for Review of Pacer Performance Vehicle Light Parts - Third Brake Light Logic Module - PP20-702

Ellen: Hey, everybody. I'm Ellen here at etrailer.com, and we're going to be taking a quick look at the pacer brake logic module. Now, this allows you to add in a third or center brake light on your trailer or your vehicle. So if you want to put this on an RV or really anything else, and you're adding in that third brake light, this allows you to do that. Basically what it does is it allows you to tap into your wiring from the factory or from maybe a four-pole wiring harness, and it'll filter out the turn signals so that you're not getting a flash on that center brake. You're only going to get the brake signal, so it only comes on when you hit the brakes, rather than coming on if the turn signals are activated.So it just is pretty simple to wire up.

You might want to watch out for putting too much power through this. Some customers have said that if you put through more than 1.5 amps, it won't work, so just keep that in mind. Will work out pretty well for most LED lights, though, since they have a pretty low power draw.There's just three wires to worry about. The green wire is what's going to actually go to your center brake light, and then you'd want to, of course, ground that brake light out. The other two wires, one is going to go to your right turn signal.

The other is going to go to your left turn signal. It doesn't really matter which wire you use. They're just there to get the signal and then filter it out so that brake signal can work. This little guy is just that kind of the brains of the operation, so you want to make sure that maybe you zip tie this off to some existing wiring or just kind of zip tie it off to something so that it's not bouncing around all over the place, but it should be pretty straightforward as far as that goes.This can be used on any kind of domestic vehicle that uses a single filament bulb. You just really want to use this any time you're using a single light as that third brake light.

So maybe again, you're adding in a LED strip to your truck or another vehicle, and adding in that third brake light function, this allow you to use that and not have it flash.As far as the size, give you some quick measurements here. We'll get about nine and a half inches of wire to work with, call it about nine of really usable length there. And the little module itself, it's just about an inch or 7/8 of an inch long and about 5/8 or maybe 3/4 of an inch in diameter. So pretty small, pretty easy to set up just about anywhere you want to.Now, if you need some butt connectors to go with this, you can find a lot of options here at etrailer.com. I would probably suggest using the pink ones.

Those will be for your smaller gauge wire, which this looks like it's about 18 gauge, so that will probably do you. If you're connecting it to anything that's a little bigger, you probably want to go with the blue, which is for 16 to 14 gauge wire, but you can find all of those here at etrailer.com to go with this install.I hope this has been helpful in deciding if this is going to be the right part for you. We do have a lot of other lighting accessories and wiring here at etrailer.com for all kinds of stuff, so check it out. Thanks for watching.

I was skeptical of this module before purchasing because I didn't know about it. Have used other brands to perform these 3rd brake wiring functions previously. Soldered it between 4-pin connector and rear tail/brake light. Simple install and works great.

PRODUCT DIDN'T WORK. I AM A PROFESSIONAL INSTALLER. PRODUCT DIDN'T WORK AT ALL. INSTEAD OF GOING THROUGH THE HEADACHE OF TRYING TO RETURN I ORDERED A TEKONSHA 2 TO 3 TAIL LIGHT CONVERTER AND USED THAT INSTEAD. THREW THIS ONE IN THE GARBAGE. MORE MONEY BUT BETTER QUALITY.

if you change your trailer lighting over to LED and have a third (center) brakelight, you need this module to make the lights work correctly. there would be a similar one factory installed, but it works only with the older incandescent type bulbs. the LED lights draw much less power and the older module is confused so if both blinker flash together along with the center brake light, get this modul. it will fix that problem

Product ordered was lost in the mail. Customer service was excellent and I received a full refund. The part then arrived the following day, almost 2 weeks after ordering. They have not indicated I would be re-invoiced, and although not a real expensive part, the fact they followed up on this matter was just great customer service. Will do business with them again. Highly recommended! The 3rd Brake Light Logic Module was just installed, and works as described. One word of caution is that if you exceed the output, ( I found it to be about 1.7 amps) the 3rd light will not work. I installed a relay, triggered by the module , that switches higher amps to the 3rd light and it works perfectly.

Works good. Has questionable reviews on a different online site but I think it’s just people who wired it incorrectly. Requires the input of both tail lights for the logic circuit to work. you need to have dual filament bulbs for tail lights, and then have a led third tail light as well. So if you don’t want to find or don’t have a constant break light wire handy easy way to tap into the factory tail lights.

  • How To Power Third Brake Light On Camper Using Trailer Connector
    If you absolutely do not want to splice into the vehicle you could use the trailer connector to power the third brake light on a truck bed camper but the issue with using the trailer connector is that the stop/turn circuits are combined. Therefore, you would need to make your own adapter using the Pacer Performance 3rd Brake Light Logic Module part # PP20-702 and the 7-Way Molded Trailer Wire Connector part # H20042. If not, the third brake light would also flash with the turn signals but...

    The running light/brake light on your salter should have a wire ran to it for the brake light and one for the running light. You'd want to use the # PP20-702 to isolate out the brake light like you need to run to the stoplight circuit of your salter light and then the current running light circuit you have present would then run to the correct circuit on the light and you'd be set.

  • Will the Third Brake Light On Camper Shell Blink When Turning.
    In order to successfully wire in a third brake light on a camper shell you need to identify first if the taillights on the vehicle are combined or separate meaning, are the stop and turn signals on the same circuit or separate. If they're separate then you can just splice into the stop light switch wire and the third brake light won't blink. If they're combined then you need the Third Brake Light Module part # PP20-702 to stop the third brake light from blinking with the turn signal.

    The Pacer Performance 3rd Brake Light Logic Module # PP20-702 separates the brake light signal from the turn signal.

The Curt option gives you 2.5 amps versus the 1.5 amps of the Pacer option. This will give you the running light, stop light, and turn signal. The ground wire of your light will connect to...

  • Troubleshooting Pacer 3rd Brake Light Module Installation on 7-way Trailer Plug
    In most cases when this occurs, it's down to the wiring being connected to the wrong spots on the 7 way trailer plug. You'll want to be sure you're using the 3 o'clock and 9 o'clock pins when looking at the back of the plug. I've attached a wiring diagram that shows this in better detail that I would ask you to confirm is how you have this wired. If this is exactly how you have it wired please let me know and I will be happy to look into this further.

    Thanks so much for the picture. It looks like you're wiring up the Pacer Module # PP20-702 to a trailer side 7-Way connector, which you then plug into the 7-Way on your truck to power the topper's lights. I was able to zoom in on the connector you're using and the issue appears to be that the yellow and brown wires are simply attached to the incorrect pins. On the connector, the pin where you have the brown (running lights) wire attached is labeled "BLACK", which is reserved for 12V...

    Yes, you can use the factory trailer connector on your 2015 Nissan Titan to power the third brake light on your Leer camper shell. That said, they don't make a plug and play harness for this so you will need to do some wiring but no splicing into the vehicle will be required.

  • Making 7-Way to Camper Shell Third Brake Light Adapter
    You can use 7-way trailer wiring with the module part # PP20-702 to provide power to the third brake light of your camper shell/cap. Basically the stop/turn circuits of the trailer wiring need to run to the yellow wires of this module and then the green wire goes to the third brake light. For an 8 foot 7-way plug and lead you'd want the part # 277-000143. The wire colors of this you'd run to the module are red and brown.

  • Third Brake Light Still Flashes With Pacer Logic Module Installed
    If the third brake light is still flashing with the Pacer Performance 3rd Brake Light Logic Module part # PP20-702 installed then the unit is either installed incorrectly or faulty.

  • Pacer Performance 3rd Brake Light Logic Module Wiring
    Whenever wiring Pacer Performance 3rd Brake Light Logic Module # # PP20-702 the yellow wires must go to each brake/turn signal and the green wire goes to the 3rd brake light. The reason why you need to hook both up is because the logic module filters out the turn signals and applies only the brake, so wiring only one may cause it to not work properly.

However, the issue that you are experiencing is that some LEDs simply don't draw enough power for the logic module to recognize a light is on therefore does not function correctly.

  • Turn Signals On Light Bar Illuminate When I Brake in 2016 Ford F-150
    The wiring system of the 2016 Ford F-150 has a combined tail light wiring system. The turn signals and brake lights are on the same circuit. Since the light bar is wired to the combined lighting system the turn signals illuminate when you press the brake and vice versa.

  • Could Pacer Performance 3rd Brake Light Logic Module # PP20-702 be Used to Power Camper Shell Light
    Your truck most likely already has a third brake light circuit ran underneath it for wiring to a truck bed camper. If you trace the trailer wiring back from the connector you should find an extra wire hanging free that has CHMSL on it that's for illuminating a camper shell third brake light. That said, the # PP20-702 can be used as a way to get a dedicated brake light circuit as well.
