Why does the right turn signal at the trailer plugin come on when i operate the left turn signal?

#1 reason is always bad GROUND. Now you really weren't all that specific about which plug. Trailer plug on the vehicle or actually on the trailer? If it's the plug on the vehicle, I would strongly suspect bad ground or installation was backwards. If on the trailer, merely backwards installation. In any case, get better trailer light performance by running separate ground wires to each individual light socket on the trailer and connect them to the ground wire at the plug so they will be grounded to the vehicle at time of connection. I do this with all of my trailer lighting and never have issues.

Why does the right turn signal come on at the trailer receptacle when the left turn signal is operated?
Check to see that you did not attach the wires from the trailer to the vehicle backwards. Also the most important thing is to be Sure that the trailer is grounded to the vehicle. The trailer ball does NOT always give you proper grounding.Run a wire attached to the trailer to the car. Or hook a set of jumper cables to both. Sometimes electricity takes the path of least resistance and can bleed over.
When towing travel trailer both blinkers blink when right turn signal?
The condition you describe suggests that the wiring to or on the trailer was not done correctly. In the towing vehicle there are two separate conductors [wires], left and right, going from the turn signal control switch, one to each of the vehicle's rear turn signal bulbs. When a vehicle is "wired" for trailer lighting, a connector plug pigtail is tapped into the vehicle's tail light, brake light, and turn signal electrical wires. The pigtailed connector plug kit usually contains a color coded schematic diagram indicating which wires on the plug pigtail are to be connected to the vehicle's lighting system, and for the trailer harness. From the connector plug at the front of the trailer tongue, there are separate wires going to the left and to the right turn signal lamps or filaments. There is one of two circumstances causing the error responsible for both turn signal bulbs on the trailer to flash at the same time: 1. The wires in the vehicle pigtail are both connected to the same turn signal wire at the rear of the towing vehicle, or 2. The two separate wires in the trailer wiring harness, or pigtail, are somehow interconnected. The correction for this is to have someone, who knows what he/she is doing, to troubleshoot the connections at the rear of the towing vehicle and in the trailer wiring harness, locate the cause of the interconnect, and properly remove the fault.

How to fix boat trailer lights Both blink while left turn signal is on Tail lights work ok when head lights are on and when right turn signal is on?
Check ground circuit Check bulbs they are duble filamented one may be burned out Seems to me there is a wire crossed at the harness. I think the vehicle left turn signal wire is hooked up to the trailer tail lights wire. Usually there are four wires at the trailer harness, yellow, green, white, and brown, The brown wire is usually the tail lights and side marker lights, the white wire is ground, the yellow and green go to the left and right signal lights.

Why does your left side trailer blinkerbrake light not work on your Avalanche The right side trailer lights work fine as do all lights on the truck itself work fine. There's no 12v at the 7-prong.?
If the Avalanche came with the factory trailering package, the trailer lights are separately fused from the other truck lights. Check your fuse panel layout for a 10-amp fuse for left side and a separate fuse for right side turn signal/brake light on the trailer.
