This is an example of installation into a Tokyo Marui M4. (Technically, a front-wired Version 2 mechbox)
Your installation doesn’t have to be the same as this – this is an example. Feel free to make your own approach and use your own method.
|Warning: If you don’t feel comfortable disassembling your gun and rewiring it, you should find someone who does instead of trying this yourself.|
First, here is a refresher on the installation theory. You want to turn this:
The Trigger Master has 3 pairs of wires and they are labeled TO MOTOR, TO BATTERY, and TO TRIGGER.
A stock M4 gearbox (a front-wired version 2) looks like this once it’s out of the gun:
I took advantage of the existing wiring as much as possible, but many people also replace the motor wires entirely. It’s up to you.
Here is what I did to the wiring. First, the motor wires:
Then the trigger wires for connecting to the Trigger Master:
Here’s the result:
Finally, I recommend installing connectors so that you can plug in (or disconnect) the entire Trigger Master if you want. (An optional connector pack is available in the store to do exactly what is shown below if you wish):
And so you wind up with something like this!
Of course, if your handguard is already filled up with a custom battery you may not have much room in there. So you might want to install the Trigger Master into the stock tube, or use a fake LAM unit to hold a battery, or anything else you come up with.
|Note: I am using a mini (600mAh) battery in this picture, but you should know that mini batteries are not the best choice for use with a Trigger Master. A mini battery’s low capacity means their voltage is unstable, and they run out of juice quickly. The Trigger Master works best with battery packs larger than a mini.|
