If everything works I suggest you don't worry - just make sure it can't rattle around making a noise.

Wiring harnesses are expensive to make and manufacturers find it more economic to make just one harness for a range of cars so it is inevitable some cars with a lower spec will have a number of spare wires, connectors etc.

SOURCE: need wiring color code for a 2000 saturn SL2 for hooking up a trailer light four pin connector

The trailer wires are left turn, right turn, running lights(the smaller elements on both tail-lights and any side lights) and ground. Energise the corresponding lights and connect the wires accordingly. Find a good ground. A piercing test probe will find the correct wire for you if you can't track it to the bulb.

SOURCE: How do I wire a 4 pin flat plug to my 1996 Mazda B2300

Rob I can't remember if your Mazda has separate brake and signal lights.
I think that model year did. If so you will need a module to make it work on a 4 pin trailer connector. These will be readily available at your local auto supplier at a reasonable price (Around $20). It will also have a wiring diagram in the package.
If the signal and the brake light are on the same bulb it will be easier.You may be able to buy a package at your auto supplier that you simply pull a plug apart at the rear of your truck and insert the complete harness.

SOURCE: tail light wiring connectors and wiring diagram

A test light checking each connector would be faster and easier to do. Maybe somebody may have a illustration for you but by far a simple test light is all you need with a helper turning on the different lights as you check them out and writing all your findings down

Check connection and ground. Since the brake light pin on your wiring harness has power, check that the wiring harness ground pin has zero ohms to ground. If the harness is good and the hitch light works on a battery, then there is either a bad connection from the pin to the hitch light or from hitch light to ground.

There should be 12 volts on the orange wire at the bulbs. The switch controls the ground side of the circuit. There should be 12 volts on the blue w/white wire at the switch. The switch will ground that wire and complete the circuit and the cargo lights will turn on.

to check the switch you would unplug it and check for continuity between the pins that the blue w/wire wire and black wire go to.

Sounds like you are missing a good ground.

Here's something to try. There should be a single black wire on the connector for the master window switch. this is the ground for all the windows. check for power by back probing that wire with the connector plugged into the switch and a window switch in either the up or down position. If you see 12 volts than the ground is bad. Use a jumper wire from that wire to a known good ground. If the windows start working than you will need to trace that wire to find the break. The most common would be in the harness in between the door and the body of the car.

If you don't see 12 volts with a switch in the up or down than remove both connectors from the switch. test continuity between the pin that the black wire goes to an any pin that the 8 wire connector plugs into. There should be continuity. If there isn't that the master switch is bad.

If you have any question let me know.

  • GEAR SELECTOR LEVER - INCREASED EFFORT TO SHIFT FROM DRIVE TO PARK
Publication Date: November 1, 2004
FORD: 2002-2005 Explorer, Mountaineer ISSUE: Some 2002-2005 Explorer 4dr/Mountaineer vehicles, may require a greater effort to move the gear selector lever (shift lever) from drive to park. This may be due to a time delay with the brake shift interlock (BSI) pin retraction.
ACTION: To service, replace the BSI switch. Refer to the following Service Procedure.
SERVICE PROCEDURE
  1. Remove the two (2) fasteners supporting the instrument panel knee bolster from below the steering column and remove the cover (Figure 1).

    tb7934b.gif
    Figure 1 - Article 04-22-12

  2. Remove the three (3) fasteners supporting the steering column lower shroud and remove the cover (Figure 2).

    tb7935b.gif
    Figure 2 - Article 04-22-12

  3. Remove the three (3) wiring bundle carrier fasteners from the bottom of the steering column to allow movement while removing the BSI switch. It may be necessary to release the connectors from the multifunction switch (Figure 3).

    tb7936b.gif
    Figure 3 - Article 04-22-12

  4. Remove the BSI fasteners (T-30 on the side and T-20 on the bottom) (Figure 4).

    tb7938a.gif
    Figure 4 - Article 04-22-12

  5. Pull the BSI tab on the bottom of the column downward to help free the BSI from the column housing.
  6. Break the two (2) side tabs off the BSI by the white wiring connector (Figure 5).

    tb7940a.gif
    Figure 5 - Article 04-22-12

  7. Push the locking tab on the white connector towards the wiring to release the connector from the BSI. Be careful not to damage the connector or wiring. If the connector does not free easily, a very small flat screwdriver may be used to help lift the locking tab (Figure 6).

    tb7941a.gif
    Figure 6 - Article 04-22-12

  8. Connect the wiring to the new BSI. Ensure all clips are fully engaged to prevent the connector from pulling free.
  9. Reinstall the BSI onto the steering column and reinstall fasteners (Figure 7).

    tb7942a.gif
    Figure 7 - Article 04-22-12

  10. Check BSI function. With the key in the accessories or run position, press the brake pedal. The BSI pin should retract on brake application, and spring up one (1) second after releasing the brake pedal. Repeat several times.
  11. Reinstall fasteners to connect wiring bundle carrier to the steering column. Make sure all connections to the multifunction switch unit are secured properly.
  12. Reassemble steering column in reverse order. Ensure rubber gap hider around shift lever is properly seated on the shroud.
  13. Cycle the shift lever from park to drive and drive back to park several times to verify improved shift effort.

Brake lights dont work,replaced bulbs,stop lite switch, no fuses blown


Trying raising the tilt on the steering wheel all the way up. Some times the connector for the MFS ( MultiFunction Switch ) pulls apart.
This is a 16 pin ( 4 rows of 4 pins ) connector behind the knee panel, Pull the knee panel ( screws on the bottom, plastic tabs on the top ) and check the connector. The harness side towards the truck ( not going to the steering wheel column ) pull up a bit of slack and zip tie it to the knee panel frame. Pull the connector apart and check the pins for discoloration. Use emery or an eraser to clean the pins. If the connector tab has been warped, you might have to zip tie the connector back together.
Not unheard of that this connector pulls apart, it was not installed on the 04+ MY F-150s, I can only assume to remove this issue.

I need to wire an electric brake controller in my truck


you can either wire it straight or gm makes a connector that plugs into the drivers side floor . theres a box down there that has a cover over it and the gm connector plugs straight to it. but be careful because i have seen several times were gm wired it wrong the stop light plug is in the wrong spot.take a test light to ground touch each connector while pressing and releasing brake pedal the one that lights the light, is your stop light look on there connector and check to see if that plug is going to the red wire if not move the red wire to that spot. as for wiring it you have to do it this way. black wire goes to constent hot, white wire goes to constent ground , blue wire goes back to your trailer plug for your electric brake, and red wire as you know by now goes to the stop light.

is the alarm factory or aftermarket?

If aftermarket - the brain will be under the dash attached somewhere near the steering column.

Look for an 10 or 12 Gauge YELLOW wire that has been cut.

This is your starter wire.

one half goes in one side of the brain, and the other comes out the other side.

either solder or use crimp-connectors to return this yellow wire back to factory.

If you no longer require the alarm - you can do the same for every other wire on the brain.






Here is the color code chart for your vehicle...

Constant 12V+ Red Ignition Switch Harness

Starter Yellow Ignition Switch Harness

Ignition Pink Ignition Switch Harness

Ignition 2 White Ignition Switch Harness
