mrasmm, you're not being rude. If I didn't make things clear, then it's my fault. Pull the 4 screws on the RX side of the case, which is the side opposite of where the revo and gyro gain screws are located. If I remember correctly, you might need to slice through some tape w/ an exacto, then pull off the side of the case Take a a small screwdriver or something and gently pry out the circuit board. Once the board is removed you will see what looks like 2 female servo plugs. I think the top is throttle, and the bottom rudder, but this is easy to test. Get 2 3" servo extension wires. One end will have a socket w/pins inside a 'hood'. Cut away the 'hood' to expose the pins. These then get inserted into the socket in the 4n1. Make sure the signal wire (orange or red depending on the brand of extension) faces toward the front (nose) end of the unit. Use a dab of hot glue to hold them in place. You don't need to solder.

see if the photo clarifies things for you.

Now Arrow....regarding your swash setup. Use servo reverse to get the servos functioning properly. For example when inputting pitch on the TX, all 3 servos need to move in the same direction. Don't worry if they all move the wrong way at this point, as long as they work together. Do not be temped to use servo reverse, and reverse all 3. Check the other cyclic functions. For elevator the two in the back move together, and the one in front moves the opposite way to tilt the swash to and fro.

Ok after you've got this part make sure the servo arms are as close to 90 degrees as is possible at neutral stick (midstick on pitch) Because the 6EXH doesn't have subtrim, the best you can do here is play w/ taking the arm of an repositioning it. Some times turning the arm around 180 will get you closer. (sounds weird, but it works)

Now if one of your functions moves the wrong way go to the SWASH menu and change the value of your mix from a positive number, to negative....or vice/versa depending on the change you want to make. That's right! If the servos move together on pitch, but the pitch is 'backward' change it in SWASH MIX!

Clear as mud eh? You might want to look for Finless Bob's Trex 450 eCPPM video. You can apply a lot of that information to the Blade.
