Grounding ECU (searched)
 

There are some grounds I cant get to to clean on my 87 n/a so I am going to try this. I just wanted to make sure this is right before doing it. I was going to take these wires and attach them together to a single wire,then to the firewall with a ring connector. I saw this on a thread but its not all clear to me so maby you all can clear this up for me. Thanks
