You're almost home!!!
what you got to do now is splice the blue fuel wire into the dash harness blue fuel wire. According to the schematic, you can do it right at the fuel switch. What i did was splice the wire into the blue fuel wire at the eight pin connector (connector between the dash harness and the rear harness). Do this, and all should be good in the world!!
Let me know how it works for you.
hope this helps!
