It may plug into the distributor cap, by where the red wire with the white connector goes, or it could be a ground strap, from the body to the back of the engine.

I am trying to replace my 2004 Saturn Vue stereo with a stereo that doesn't have a place to put the copper wire. The unit lights up, but no power. It is receiving power as indicated by blinking light...


I just did this on my 03 Vue. That copper wire is your ground. The ground is the black wire on your new stereo. The copper wire has a connector at the end of it, I believe it is a female end. You can get a male end for the black wire and simply plug it into the end of the copper wire. I would then take some electrical tape and wrap it up. I hope that helps.

I bought some halo driving lights for my '03 GMC Sierra 1500, they came with a wiring harness, switch and everything needed for installation except for installation instructions. Help PLEASE!


Tools recommended for this job: wire stripper, wire crimper, volt meter, 4x quick wire connectors, 4x male crimp connectors, 4x female crimp connectors
  1. First, tape the halo and/or LED wires to the back of the headlights to keep them from tangling.
  2. Keep the pairs in order by their color, e.g. black, black (ground) and Red, Red (positive). Note: positive and ground wires might not always be black and red.
  3. Remove some of the plastic shielding at the end of the wires to expose enough copper wire, next twist the copper together to strengthen it.
  4. Shove the twisted copper into a crimp connector; crimp the location where wire and the connector end overlaps, wrap with electrical tape to secure it.
  5. Two extra wires in black and red will be helpful to make the halo/LED wire longer to easier installation. Remove shielding: show copper: use the connectors: connect the positive and ground from the headlights.
  6. Next step, turn the headlights inside the car to the [on] position.
  7. Take the volt meter and connect the negative to the negative on the battery (please use extreme precaution when doing so).
  8. The headlight harness usually will have [3] wires, generally red, black, green (headlights, ground, turn signal). Use the volt meter to test which wire will have power running through it (since the headlight is in the [on] position) which will be the headlight wire.
  9. Use the quick connector to connect the extra wires (red) to the power wire on the harness and black to the ground. This will split the current coming from the harness. Crimp the connectors and use electrical tape to secure it.
  10. Now connect the projector headlight halo wires and the harness from the car.
  11. No wires should be left over unconnected.
  12. The installation is now complete.

How do you install an electronic trailer brake controller in a 1995 GMC Suburban 1500?


a brake controller has 4 wires on it, Black, white, blue,red.

Black is positive battery 12 volts connect to 30 amp circuit breaker to the battery

White goes to good solid ground

red connects to white wire from the brake switch

blue wire connects to 7 way trailer connector at rear of truck. If the truck has trailer package you will find the blue wire and red wires under brake booster taped to the harness you can connect your blue brake control wire to that blue wire. At the rear of the truck the other end of the blue wire will be taped to a harness under the rear of the truck. you will have to now connect the blue wire to the blue input on your 7 way connector

The plug that connects to the alternator has three


Yes the White wire is the reason. It goes to the Internal Regulator.
As you view the connector that plugs into your alternator, look at where the lock tab is.
Lock tab on TOP. The Black wire goes to the Left side. The White wire goes to the Right side.

The Black wire, ties into the Red wire down in the wire loom. (The Red wire goes to the starter solenoid, and this is connected straight to the battery. This is why the Red, AND the Black wire, are both Hot wires)

The White wire goes through the bulkhead wire loom, and to the bulkhead connector.

(Down under the steering shaft, and on the firewall, you'll see a rectangular Black box shape, with a Bunch of wires, coming into it from the engine compartment. The bulkhead connector is two pieces. Following it through the firewall, the other side of it is the fuse panel)

Where the White wire connects in the fuse panel,
it should go straight to the ACC fuse. (Accessory)

Runs good with ecm un-plugged in, but when plugged in runs rough


Static timing should be 10 deg btdc you can check that timing when you disconect the tan/black trace wire there should be a weatherproof connector for this wire near the Left hand inner skirt this wire is called the set timing connector and when disconnected stops the ecm from adjusting the timing.
