I figured it out. This wire is a ground and the car would not run without it connected.
It can be attached to the bottom of the master cylinder or on the drivers side frame between the firewall and the radiator. Follow the brake lines coming out of the master cylinder.
any leak on your drivers door, or firewall. could be just about anything.
It's at at the top of the engine between the end of the valve cover and firewall. It has 1 connector coming out of it. It is adjustable. That's how you set your timing.. by loosening a single bolt on the drivers side, you can make adjustments.
It is behind the engine ,in the exhaustpipe, right in front of the firewall. It has one wire coming out of it and connects to a connector in a clip on the firewall, right next to the heater fan motor .
driver side of the motor towards the firewall. It is a UFO shaped object with 3 hoses coming out of it and an electrical connector.
Drivers side, mounted on the firewall, behind the master cylinder. Coming from that booster is a large vacuum line.
First, remove the throttle cable from the gas pedal. This can be done easily by hand, since the connector attaching the pedal to the cable is not very strong. Next, using pliers, preferably needle nose, press down on the two plastic tabs coming through the firewall on the cab side. An easy way is to look at the throttle cable connector located on the drivers side next to the TBI. This is the same type of connector, so you should be able to come up with a plan of attack by looking at this. It's kind of tight under the dash where the cable comes through, with a dash bracket and heater routing, but with a little patience, you should do just fine.
Passenger side of motor at the bottom, coming from the firewall to the front of the car, it is just before the fuel pump.
IT IS LOCATED ON THE DRIVERS SIDE IN LINE WITH THE LOWER RADIATOR HOSE COMING FROM THE DRIVERS SIDE, BOTTOM ON THE RADIATOR. IT IS IN A SOMEWHAT ROUND HOUSING.
If it's a 4 cyl the fuel filter is located on the drivers side of the engine compartment near the firewall. It is a cylinder with a fuel line coming in and going out of it.
2 should be in wires coming off the alternator, and i believe about 5 more on drivers side tucked in fender near the firewall next to the junction block.
On the drivers side of the throttle body. little black box with 2 screws and 3 wire connector coming out of top
