Finally have some time off to finish this.
Wow. I must've been tired. If I had only got off my rolling stool and LOOKED I would've seen a perfect tab on the strut tower where the existing ground goes.
Anyone know if the rear seat bracket or seat belt bolt is a good place to ground? I read somewhere that the bolt the seat belt went through is a poor choice.
Also, 120+ views and no response? Really? What exactly is anyone expecting to see when I'm posting the question in the title?
