WWYD wiring advice.

I'm wiring in my ignition box, coil and other things. Im not trying for the hidden wires but would like whats there to be neat and contained. I struggle with cutting them. You can see I have the coil mounted close to the box, the power wire done have far to go. Also in the photo is my 12v key on power.

Do I dare trim these wires back? Ive always hated pulling a radio to find out someone else had been there and cut the wires so damn short you cant do nothing with them. Thoughts?
