OK I would like to run it with the same wire off the stock harness right there, What wire is it that I need to tap into?
Thanks!

You don't want to run the inline pump directly off the same power line as the stock pump. The wire isn't big enough, and voltage drop on a pump power supply can be a major problem with reduced fuel flow.

You want to run a dedicated power wire, with a fuse, directly from the terminial in the red +12V "box" next to the battery. Run that wire to the pump, through a 30-amp relay. Take a "signal" wire off the existing fuel pump relay to activate the inline fuel pump relay so they work together.

The existing fuel pump chassis plug is under the floor/bottom of the car on the drivers side, where the body kicks up over the axle. You need to tap into the grey wire in that connector.

There is a good wiring diagram in the manual for the NOS-5176 kit, and if you can't follow what I wrote above, I could fax you a copy of it on Monday.
