Where are the ground wires for the ECM that I need to check?
Where exactly are the ground wires for the ecm that I need to check and how many are there? The bulletin says to check the ground wires for the communication network lines which are lines h and l. But I can not find any specifics on where these grounds are for the ecm.

What do green wires do in an outlet?
Green wires connect to the grounding terminal in an outlet box and run to the ground bus bar in an electrical panel. Their primary purpose is to ground an electrical circuit and provide a path to ground for a circuit’s electric current if a live wire within the circuit interacts metal of another conductive material.
Where are red electrical wires most commonly found?
They are most commonly found in residential buildings. Red electrical wires are the secondary live wires in 220-volt circuits and are commonly found in a sheathed, multi-conductor cable. These wires are typically used for switch wiring as well as the interconnection between smoke detectors hard-wired into the power system.
Where does the pink wire go in a PCM?
This wire runs from C100 Pin C to underhood fuse block C2 – E2. Inside the fuse block, it turns around and comes back out on C2 – F2. F2 then runs to the PCM and Transmission. You could also take the PINK wire out of C2-F2 and move it to location that has key hot 12v+.

Where are the pink wires in the fuse block?
Inside the fuse block, it turns around, comes out on C2 pin E11 (two pink wires, one to Trans Pin E, other to PCM Pin 75) Just like 99-02, you need this circuit powered up. You can power the wire at C1-C9, or move the wire at C2-E11 to a position with power in it.
Where does the c7-a9-red wire come from?
C7 – A – REDthis wire feeds 12v Battery+ FROM fuse (IGN B 40A) TO ignition switch, hot at all times. C1 – A9 – PINK – this wire is FROM ignition switch, hot in RUN, START. This powers up multiple fuses on underhood block and activates the IGN 1 Relay. *SAME as prior years
What causes bad ground connections on a car?
When checking ground connections, make sure the terminals attach to a non-painted surface. You want to connect to bare metal. Paint, corrosion, greasy surfaces, frayed or broken wires, and loose connections are the main cause of bad automotive grounds.
What should I do if my fuel pump is not grounding?
If the ignition system is equipped with a distributor, you can disconnect the high tension cable from the distributor cap and ground it to the engine (bolt or bracket) using a jumper wire. On other systems, you can remove the fuel pump fuse.
What’s the best way to check a transmission ground?
Check individual chassis grounds by taking a voltage drop across each ground strap on the transmission. Voltage drop should be 0.2 volts or lower. Clean, repair or replace transmission grounds as necessary. Remove grease, rust and paint from under ground terminals, or replace damaged ground straps. V. Why It’s Important to Find and Fix Bad Grounds
