That wire is under the hood on the passenger side firewall. You might need to remove a plastic cover to see it. It is just a single wire with a weatherpak connector. When you find the wire you have to have the engine running before you unplug it, and you must shut the engine off before plugging it back in.

I would like to know the color code of the wires to the rear lights to hook up trailer wires. Tailights, break lights, left and right turn signals

brake lights, white/tan stripe
tail lights, black/yellow stripe
left turn, light green
right turn, tan
ground, black

Note that your car has separate filaments for brakes and turns, so you cannot use the standard 4-prong trailer connector and will need an extra filament in your trailer lights.
Please let me know if you have questions, and thanks for using FixYa.

What is the ignition timing for a 95 Chevy pick up 5.7L engine? What wire do I unplug to set ignition timing?

The timing is to be set at zero TDC.The connector is on the passengers side under the hood against the fire wall.There might be a plastic cover over it.It is a tan wire with a black stripe.Sometimes it will be in the passengers side under the the blower motor.Same colors on the wire.The check engine light will come on when the connector is unplugged but it will go off after it is plugged back in and the key is cycled on then back on or start.Hope this helps.Good luck.

Timing a 92 chevy s10

The tan colored wire with a black stripe is located either breaking out of the wire harness near the distributor, or under the carpet on the passenger side floor, (look up towards the top right hand corner, and you might also have to remove the kick panel to see it if it got stuffed behind the kick panel).

It is a Tan colored wire with a Black stripe, and it will usually have a unique black connector.

You will know it is the right wire because when it is dis-connected at the connector the idle and timing will change, and the check-engine light will come on.

Set the timing where you want it to be, then turn off the ignition and re-connect the wire to the electronic timing control. Re-start the vehicle and the check-engine light should go out, that is of course if it was not already on before because of another problem.

You can re-set the check-engine light by dis-connecting the battery ground for three minutes.

I am having trouble setting the timing on a 262(4.3l)chevy vortec engine 1995

You have to put the Ignition Control (IC) system in the bypass mode by disconnecting the "set timing" connector. This is a single wire sealed connector that has a tan with black striped lead. The location of the "set timing" connector with a Powertrain Control Module (PCM) controller is near the PCM connectors in the passenger compartment. Unplug connector (tan/black stripe) start engine set timing to 0 TDC, TURN OFF ENGINE, re-connect timing connector

Firing Order 1 - 6 - 5 - 4 - 3 - 2
Drivers side: 1 - 3 - 5
Passenger's side 2 - 4 - 6

Where can i get the specs for ignition timing on a 1989 GMC K1500 Pickup

Note: The Timing Connector breaks out of the engine wiring harness conduit adjacent to the distributer. It is a single wire sealed connector that has a tan with black stripe lead.
Note: Timing specifications are listed on the Vehicle Emissions Control Information label under the hood. Always follow the Vehicle Emissions Control Information label procedures first before using the following procedure. PROCEDURE:
Set timing under the following conditions:
  • Normal operating temperature.
  • Air cleaner installed.
  • A/C "OFF".
  • Transmission in neutral.
  • Disconnect SET TIMING connector (tan/black wire) located in the harness close to the distributor. DO NOT disconnect the 4 wire connector at the distributor.
  • Connect timing light and adjust as necessary by loosening hold down bolt and rotating distributor.
Base Timing, with Manual and Automatic Transmissions: 00(TDC)
  • Tighten hold down and recheck the timing.
  • Stop the engine and connect SET TIMING connector.
  • Clear ECM trouble code by disconnecting ECM power source.

I need to know the timing specs for a 1994 Chevy 4.3 V6 Engine.

Following the label under the hood. Put in base timing mode by unplugging a wire connector, it usually tells you where it is. This will turn on the check engine light to tell you you're in base timing mode and takes the ECM out of the loop. Should be a single wire tan in color with a black stripe and black connector. If you not sure where the connector is, it's in the passenger compartment behind the carpet, and blower heater. Just follow along the wire harness from the ECM. Remeber a single wire tan in color with a black stripe and black connector. Good luck and hope this helps, keep me posted if you have any other questions. Be glad to answer any questions and if the label is missing let me know.
