H. Following the diagram (see

Figs. 11-c, 11d), wire the

fuel pump and relay. Use the supplied tie wraps to run
the wire and keep it away from heat/abrasion. Use the
supplied 8mm nut to connect the main power lead on
the relay to the factory fuse/power box underhood (the
factory has provided two open power lugs under the
power box cover). Tap the yellow relay wire (terminal
#87) into the solid gray wire in the harness running
along the driver's side frame member. Use the supplied
wire tap.
