Fusing the injector B+ wires ..?

[yossarian19]

So, I'm modding my 02 Vortec 4.8 harness.
I think what I see going on is that the power to the injectors is from the fuse box and they are switched on the ground side by the computer.
I want to put the driver's side injectors on one fuse and the passenger's on another.
So, do I strip a bit of wire off each injector's power (pink) wire & join them together, then from that gang of 4 to the fuse? Any suggestions about technique? I'm considering a soldered gang w/ one heavier wire going to the fuse & heat shrink to seal it up.
How did you guys do it?
