How can I connect new harness?

Here's a wiring guide for the fuel pump on a 2000 Cadillac Deville: 1. Remove the fuel tank and access the fuel pump module. 2. Disconnect the electrical connector from the top of the fuel pump module. 3. Locate the wiring harness that runs from the fuel pump module to the car's electrical system. 4. Cut the wires on the old fuel pump module connector, leaving enough wire to splice the new connector onto. 5. Connect the black wire from the new fuel pump module connector to the black wire in the car's wiring harness. 6. Connect the purple wire from the new fuel pump module connector to the purple wire in the car's wiring harness. 7. Connect the gray wire from the new fuel pump module connector to the gray wire in the car's wiring harness. 8. Connect the black/white wire from the new fuel pump module connector to the black/white wire in the car's wiring harness. 9. Connect the new fuel pump module electrical connector to the car's wiring harness connector. 10. Reinstall the fuel tank. Note that it is important to follow the wiring guide carefully to ensure proper installation and avoid damaging the fuel pump or electrical system. If you are unsure about any step of the process, it is recommended to seek assistance from a professional mechanic or refer to the vehicle's service manual.

1993 ford ranger. no car told at all 2.5Liter sourced from wow, that is a hard nut to crack leaving all that out. my guess 1998 2.5L

the old PCM will not like what you just did.
for sure CMP or CKP sensors.
also if one sensor is hall and old car is not it will and
vice versa. came new with 3 engine and not 2.5 ever.
the 2.3L CKP is 4 wire, (one is 12vdc LT/GN wire) so is Hall sensor
to the ICm
so running the old ICm or new?
the 2.3L runs twin 2coil pack pairs in wasted spark mode
wild guess

• 2.5 L OHC I4 (gasoline) (1998-2001)

the 1998 engines, uses its own ECU with NO ICM at all.
and has 2 wire (weak signal, 1v , to PCM direct ,no icm uses
there is CMP sensor too that is for injector firing only
the correct swap is all harnesses under hood and PCM swapped
from new engine donor car, and more, even dash to engine harness.
the current new CMP is useless to any 1993 ECu, the 2.5 liter CKP will NEVER fire the OLD ICU< ever
worse yet the reluctor tone wheel can totally different .

Be absolutely certain that you understand the actual use of each and every wire leading to the stock radio before mating them [in a bridged fashion] to the new harness for the replacement radio. The actual use must be the same for each wire to be adapted from old to new. If different descriptions are given between OEM and replacement for given wire usage, consult someone more knowledgeable before connecting them together.

the connector is the same on both the old harness and the new pigtail. As long as you orientate the connectors the same way you just match up the wires. let me try to explain it this way. If you hold the old connector so the part that holds the connector to the sensor is facing up. Hold the new connector exactly the same way. cut the left wire on both and connect the new connector wire to the old wiring harness. Then cut the center wire and connect them. then cut the right wire and connect. No wiring diagram needed.

One thing I will add is to stagger the new connections. Meaning do nut cut them at the place. Cut one wire then cut the next about an inch or so further and then cut the next about an inch or so further than that. This will prevent the new connections from potentially shorting to each other and will keep the harness from becoming really bulky with all the but connectors in the same location.

WOW?
yes, the new ECU;PCM uses a real electronic 3 wire
hall sensor for speed, (or uses ABS if opted)
swaps are complex. we need
what you had before the swap (drive line)
and what was removed from the 2003... every part.

without any info,,i;e,,make,model,year,
problem,,WHAT KIND OF ANSWER
DO YOU EXPECT???

I have the same problem.

If it is the correct fuel pump - where it unplugged, it should just plug in where the old one did.

-open hood
-locate 4 retaining nuts and bolts
-undo nuts
-open wiring harness quick connect (push tab and pull apart)
-remove old headlight
-install new headlight into correct position
-connect new headlight to wiring harness
-attach 4 retaining screws
-turn on headlights against garage door
-tighten top and bottom bolts until desired height setting for lights

put into the same order as old connector
