Since you have a 2008 Chevy Tahoe the likely problem is that the fuse for a brake controller is not present or you need to make some connections under the hood to make everything fully functional. I do not believe that you have blown a fuse.
I have included a link to an article that explains the under the hood connections and fuse locations associated with a brake controller on your SUV. view full answer...
For your 2013 Chevy Tahoe, the wiring harness adapter # 3016-P is not a fit. There is not a brake controller port available in your Tahoe, so you must be plugging it into something else and that is why you are having an issue starting the vehicle when it is connected to your # 90195. There is not a brake controller plug present under the dash, but the needed wires are already run. You will connect the brake controller wiring with the vehicle wiring already present under the dash.

Thank you for your recent purchases from etrailer.
I would like to suggest some additional testing before you return the Curt Discovery Trailer Brake Controller # C84VV. This will help isolate the problem and confirm whether the unit is indeed defective.
The code OL indicates that the controller has sensed an overload condition. Disconnect the trailer from the Tahoe. Apply your grounded tester to the pins at the 5-o-clock and 7-o-clock positions on the Tahoe 7-way, as shown on the linked... view full answer...
The problem is that on your 2007 Chevy Tahoe, the turn signals on the vehicle are on a separate circuit than the brake lights. Trailers use a combined stop and turn circuit. When trailer wiring is added to a vehicle, vehicles with separate turn and brake lights get those signals converted to a single function by a converter whether from the factory or aftermarket.
If yours is from the factory, it sounds like something has gone wrong, but I can tell you what to look for. First, take a look... view full answer...
From what you described it sounds like you have some wires crossing paths somewhere on your 2002 Chevrolet Tahoe. With everything wired correctly the only time you should be seeing the brakes on your trailer activated is when you either press your brake pedal (depending on the brake controller) or using the manual override lever (every controller).
What I recommend doing is checking the 7-Way on your Tahoe to make sure everything is functioning properly. Using a circuit tester like part... view full answer...
Under the hood of your 2001 Chevy Tahoe is a few connections that will need to be made in order for the brake output circuit of the 7-way to be connected to the brake controller.

First you will need to ensure the lights are flashing blue when you connect the Curt Echo # C51180. If your blue lights are not flashing when installing the Curt Echo with the ignition on, you will then need to check to verify if your 7-way is getting power. A Test Light # PTW2993 can be used to check the blade located at the 1 o'clock position has power(see image). If you do not have power at this terminal you will need to check the fuses in your 2016 Chevrolet Tahoe to verify they are... view full answer...
The first thing to do is take a look at your owner's manual to locate any trailer fuses or relays and ensure they are all there and in working order. If they are, in order to determine the specific problem you will need to purchase a circuit tester if you do not have one - the very handy Cordless Circuit Tester # PTW2979 - and test the connector on your vehicle after disconnecting it from your trailer. Check the wiring going into your harness from your tail lights to see if those wires... view full answer...
This is the first time I have heard of this issue with the Hopkins InSIGHT brake controller. It sounds like one of two things. First, it is possible that the brake controller red wire is not attached to the correct wire on your 2008 Chevy Tahoe. It should be attached to the Tahoe Light Blue with white stripe.
If that is correct might have a short somewhere. There are ways to test the controller to see if it is the problem. In the Tahoe cab you will need to sever the blue wire several inches... view full answer...
The codes you are getting on your Primus brake controller in a heavy rain could be caused by the excessive water you said you were driving in. You probably got the S.H code which means a short and o,L means an overload.
You can test this by making the trailer connectors are completely dry and free of corrosion and testing it when it is not raining. Also you may want to use some dielectric grease like part # 11755 that helps keep moisture and dirt out of the electrical connections.

A faulty circuit breaker/fuse should not cause a gauge display to have an improper reading. It could however be the sensor or wiring that is bad causing a false reading. For example, the coolant temperature sensor usually located on the water neck can give a false high reading if the sensor has gone out. The only solution for this would be to replace the sensor. However, the likelihood that the sensor has failed in comparison to the oil indeed being hot is low. You can check if the oil... view full answer...
It sounds like the tow package running light fuse is blown. There is a power distribution panel under the hood. When you remove the cover there will be a legend on the underside indication where the tow package fuses are located. The running light fuse for this circuit should be located in this panel also.
If a tow package fuse is blown check the trailer wiring for a short on the taillight circuit before reconnecting it to the vehicle.
If you find that the fuses are good, the next thing... view full answer...
The first thing you should do is make sure that the red wire on the Plug-in Simple Brake Wiring Adapter, item # HM47795, is connected to the correct port in the connector. For your 2001 Chevy Tahoe Z71 you will need to insert the red wire into slot A. This slot is the top left slot, with the blue locking tab up and the connector facing away from you, see photo at right. If your brake controller comes on when the headlights are turned on you definitely have the red wire in the wrong location.

It sounds like you could have an issue on the vehicle and trailer. If you are not getting any power to the running light pin on the vehicle side trailer connector this is usually caused by a blown fuse. I checked in the owner's manual for a 2019 Chevrolet Tahoe and it look's like the trailer running light fuse is located in the engine bay fuse box, slot #41.
In order to troubleshoot the trailer I recommend you first reground the trailer connector and then apply 12 volt power to the trailer... view full answer...
There are several things you can check to determine why a trailer wiring circuit is not working. First, you will want to test the vehicle side trailer connector using a circuit tester such as #PTW2993. Have someone sit in the vehicle and go through the light functions while testing. If everything works on the vehicle you can move on.
If a circuit is not working on the vehicle, then make sure the trailer connector is clean and free of corrosion inside and out and inspect the wiring, fuses,... view full answer...
There are two possibilities for the problem you are experiencing. Either the wiring on your 2004 Chevy Tahoe is incorrect, or the wiring of your trailer is bad.
The first thing I would do is test the 7-way on your Tahoe by function to determine if it is the problem. To do that you will need a buddy to apply the different brake and taillight functions of your vehicle while you test for the correct voltage with a Circuit Tester like # PTW2993 on the 7-way. I attached a video on how to do... view full answer...
Yes, the reason the lights on your trailer are not getting power is because you created a short when the wires touched. You will need to replace the wire that shorted with the wire gauge you were using, likely 16 gauge # 16-1-1, 14 gauge # DW07550-1 or 12 gauge # 12-1-1. You will need to use Heat Shrink Butt Connector - 16-14 Gauge # DW05744-5 or 12-10 Gauge # DW05745-5 and Heat Gun # ALL836717 if you don't have one.

First, try unplugging it for 5 minutes and plug it back in at an appropriate mounting angle and inline with the direction of travel. It may have been bumped on accident and it wasn't at the proper angle anymore. When the brake controller was flashing, was it a letter code such as N.C., S.H or O.L or lines? If you can let me know, I may be able to pinpoint the problem.
Here is some additional reasons why your brake controller such as # TK90160 is flashing even when your trailer is disconnected:

The most common issue with air bags like the Firestone Coil-Rite Air Helper Springs part # F4135 is the connection of the air line to the other components.
It is recommended to use a spray bottle with soap water to spray each fitting to see which is leaking. Once you have found it remove the air line and re cut it. Make sure to get a very straight even cut. An angled or crooked cut will cause leaking every time. Then place it back in and retest. view full answer...
The error code SH for a short on the brake circuit could be due to corrosion or damage in either the Tahoe trailer wiring, the wiring on the trailer itself or a malfunction in the brake controller. If you have access to another trailer this will allow you to test the vehicle to see if the same problem occurs with the other trailer; same goes for trying a different tow vehicle. This process does not find the problem but it does at least isolate it to the truck or trailer.
