I'm trying to ground my ecu and i want to know if i should ground both of the wires shown and should i tie them all together then and add a new ground and solder them??????
Thanks,Brian

 

wow if that's your car's metal, it's really rusted. heh you should get rid of rust first.

 

If the two black ones are the ones your talking about and IF they are going to pins 2R, 3A and 3G, then yes. you can tie them all together and ground them as on one ground lug.

I think that is what I'm seeing in the picture. Two black wire coming together in a splice and leaving as one wire and the other black wire over there by itself makes three.

Right now they ground on the top of the engine on a single lug. Adding another ground won't hurt. I put mine on the ECU bracket hold down stud.

 

sweet thanks.............. but what is that gray wire that jumps off of where the wires are crimped together??

 

I might be wrong, but I think it's the shielded signal wire for the AFM or the O2 sensor.

It's the shield for the O2 if its center conductor is going to pin 2D. It gets grounded. The shield that is, not the center conductor.

 

ok thanks i really appreciate it <BRIAN>
