So my engine swap continues to give me headaches lol, one of the grounds on the back of the has broke. It's the thick one, believe it's the ground for all the sensors and fuel pump. Car runs fine as long as I have my scanner plugged up and completing the ground.
Problem is that wire is so short now I can't get a crimp on it to extend and ground it. Anyone know where that wire originates from so I can make a new ground?

Ya know ya can ground it anywhere…? ground it from the front/side of block to the firewall, do a second one to the frame and a third one to the battery

 

Well yeah clearly. But I can't get a ring terminal on the wire anymore to get it grounded. So I need to know where the ground wire comes from so I can reground it. I know what the problem is, I simply can't fix t because the wire is behind the engine and I can't get crimpers or a soldering iron behind the engine and under the cowl to fix it. I need to know where that wire originates from so I can make a whole new ground wire and then i can ground it to the head like factory.

 

What color are your PCM connectors? Red and Blue? Or blue and green? If its a PCM ground that you are curious about, you can find the location of the ground wires at the link below. Simply de-pin the broken wire out of the PCM connector and replace it with another wire. You can get replacement wires out of a dead car or truck at your local junk yard.

They make crimpers with a 90 degree head for places like that.

 

Take a fresh single edge razor blade, "Carefully" slit open the LOOM, chase down another 8 inches of wire, scrape it down clean and bright, solder and heat shrink an EXTENSION and good grade tin plated ring terminal...... Wrap it up, and bolt it down.
