Although this installation manual is from 9/17, it's the newer version of what originally came with the kits.

It's somewhat improved and has better pictures and illustrations.

Although it lists fuel pump PWM in the table of contents, there's no discussion of it. It's not believed any of the LS kits came with the needed PWM relay to actually make it a working feature. I believe this is because some fuel pumps will burn out when driven with PWM power.
