If you’ve ever thought about rewiring your AEG (Automatic Electric Gun), this guide is for you. Rewiring can boost your AEG’s performance, and today, I'll walk you through the process using my Wraith as an example. Whether you're upgrading to Deans connectors, ultra plugs, or simply looking to enhance your airsoft gun’s efficiency, this guide will cover everything you need to know.

Why Rewire Your AEG?

Rewiring your airsoft gun with higher-quality wires and connectors can improve power efficiency, increase trigger response, and extend the life of your motor and battery. Most AEGs come with 20-gauge wiring, but upgrading to 16-gauge wiring or thicker will allow more current to flow with less resistance, giving you a performance edge in the field.

What You’ll Need

Before you start, make sure you have the following tools and materials:

• Wire:16-gauge wire is recommended. The lower the gauge, the thicker the wire, which means better performance for your AEG.
• Connectors:You’ll need connectors for your motor and the battery. Most stock AEGs come with Tamiya connectors, but upgrading to Deans or ultra plugs is highly recommended for better conductivity and easier connections.
• Heat Shrink Tubing:Essential for insulating your connections.
• Soldering Iron and Solder:Necessary for making solid, conductive connections.
• Wire Cutters and Strippers:For cutting and stripping your wires.
• Needle Nose Pliers:Handy for holding and positioning small components.
• Heat Gun or Lighter:Used to shrink the heat shrink tubing over your connections.

Step 1: Disassemble and Clean

Start by completely disassembling your AEG and cleaning all parts. This step is crucial, as any dirt or grease can interfere with your rewiring efforts. Once disassembled, remove all existing wires to prepare for the new setup.

Step 2: Understanding MOSFET Configurations

If you’re planning to install a MOSFET (which I highly recommend), there are two configurations to choose from: single signal wire and dual signal wire. The dual signal wire setup is the superior option, providing a cleaner, faster trigger response by separating the signal wires from the power-carrying wires. This setup also reduces wear on your trigger contacts.

Step 3: Measuring and Cutting the Wire

Measure the distance between your MOSFET and the motor, ensuring the wires are long enough to reach comfortably. Remember, the positive wire may need to be slightly longer to accommodate its routing. Cut the wires according to these measurements.

Step 4: Soldering Motor Connectors

Solder the motor connectors first. Strip about a centimeter of insulation from the ends of the wires, then crimp and solder the connectors in place. Apply heat shrink tubing over the connections to protect them from damage.

Step 5: Attaching Ultra Plug Connectors

Next, solder the ultra plug connectors to the other end of the wires. Again, make sure to slide the heat shrink tubing onto the wires before soldering, as it may be difficult to add afterward. Solder the wires onto the connectors, then shrink the tubing to secure everything in place.

Step 6: Testing Your Wiring

Before reassembling your AEG, test the wiring by plugging in the motor and battery. Pull the trigger to ensure the motor spins correctly. If it works, you're good to go!

Step 7: Reinforce Vulnerable Areas

Check for any areas where the wires might be exposed to sharp edges or threading, such as where the wires exit the gearbox. Reinforce these areas with additional heat shrink tubing to prevent wear and tear.

Step 8: Reassemble and Final Test

Once you’ve confirmed that everything is working, reassemble your AEG. Perform one final test to ensure that your rewiring was successful and that the gun cycles correctly.

Conclusion

Rewiring your AEG might seem daunting, but it’s a rewarding way to boost your airsoft gun’s performance. Whether you're looking for improved power efficiency, a faster trigger response, or simply want to deepen your understanding of your gear, this guide has you covered.
