Wiring the wires from the unit to the wires to the connecting harness

It is generally not recommended to rearrange the pins on a wiring harness or a head unit as it can result in damage to the unit or create electrical problems. Instead, you may want to consider using a wiring adapter or a different wiring harness that is compatible with your aftermarket head unit.
Wiring adapters are designed to connect an aftermarket head unit to a vehicle's factory wiring harness, allowing you to install the new head unit without modifying the original wiring. These adapters are available for a wide range of vehicles and head units and can make the installation process easier and more reliable.
If a wiring adapter is not available for your vehicle, you may need to use a different wiring harness that is compatible with your head unit. Some head units come with a universal wiring harness that can be used with a variety of vehicles, or you may be able to purchase a specific wiring harness for your vehicle and head unit combination.
Overall, it is generally best to use a wiring adapter or a compatible wiring harness rather than attempting to modify the wiring yourself. This can help ensure that the installation is safe and reliable and can prevent potential damage to the head unit or the vehicle.

so you have 3 wires that make the stereo turn on red is trigger from when you turn the key whatever wire turns active on the cars wire harness that needs to be conneced to the red wire on the head unit. yellow wire need to be connected to the cars wire harness that has constant power on even when the cars key is in the off position. Last connection should always be the ground connection should be made when connecting a stereo unit. You can use the ground off the cars wire harness or you can make your own ground using a sheet metal screw and tapping into the cars sub framing behind the unit with a loop connector at the screw end and a barrel connector to the stereo end. Them 3 wires red ,yellow,and black are the only 3 wires that need to be connect to turn the unit on and off. If your stereo doesn't hold its memory on the settings everytime you turn the car off you have the red and yellow wire crossed and you would need to swap them. goodluck

If you are referring to installation and have the aftermarket wiring harness, The wires should be color coded. RED, YELLOW, & BLACK are power, ignition and ground. These should correspond to matching wires on the back of the head unit (CD player). Match the colored wires from the back of the unit to the same colored wires on the aftermarket harness and then connect them using wire connectors/wire nuts. Once you have them into the correct order the aftermarket harness should connect into the harness in your vehicle. I hope this answers your question =)

For starters, I want to make sure. You did purchase a wiring harness that "plugs" into your vehicle, right? If not and you are attempting to hardwire to your vehicle, STOP! You run the risk of frying your entire electrical system. If you purchased a harness you can crip the wires from your head unit to the harness and the harness plugs in. DO NOT crip wires directly. You are experiencing just a little of what can happen. However, if you did purchase the correct harness, you need to check all our crimps again. Hope this helps.

HI,
If you make a close verification on the back side of kenwood DNX9980HD 20 PIN HARNESS then you can see a Light Blue wire with Yellow stip ( BLUE/YELLOW) on it with a identification mark as "Remote cont". You have connect this wire to the Brown wire with white strip (BROWN/WHITE) from the 20 PIN HARNESS of AXXESS ASWC . There wil be a brown wire also from this 20 PIN HARNESS of AXXESS ASWC, leave it free insulated. It will not use with kenwood radios. You have to check for LIGHT BLUE with WHITE strip. There is also two other blue wires of which one with white strip. You hve to choose the light blue wire.
ok

you don't stick wires in the holes. they make a male harness for the female harness you're messing with. your radio should have a harness that plugs into it with wires connected to it. then you buy the install harness for your year, make, and model car along with a dash kit if needed. then you proceed to connect the color coded wires from the head unit harness to the install harness you bought WITH CRIMP CONNECTORS. not packing tape or shrink wrap or any other thing you can think of to insulate the bare wires. crimp caps or **** connectors with electrical tape works fine.

easiest way is to also buy the wiring adapter almost all elect brake units sell a vehicle specific wire harness that u unplug brake wire harness plug in other harness than plug in brake harness and just connect the wires to elect brake controller eliminates cutting and splicing ur brake harness about $18

HI, this is a Serial communication error. This issue will more than likely concern the wiring harness.

The Communication between the Central Control Unit (CCU) and the Motor Control Unit (MCU) cannot be sent correctly.

Potential Causes

• Check Wire Harness connections to the MCU, the motor, and Central Control Unit (CCU)
• Check the Drive system for any worn or failed components
• Check MCU
• Check CCU
• Check Motor
• Check Wire Harness

Replace failed component.((Usually the wiring harness will need to be replaced))

Do you need a wiring harness for the back of the unit? All you have to do is google "wiring harness for vr3 cd400 and you will have allot of options to choose from. If you connected the red which is 12v +, yellow connects to 12v for radio memory, and black goes to ground. Brown is for external amp turn on. Check to make sure your connections are correct. Do you have an adapter harness that plugs into the factory radio harness? You can get one from Wal-Mart or best buy or online. So you don't have to cut/splice into the wiring harness coming from the stock radio.
