I'm going to do the Big 3 on my car this weekend and I have the guides and I've searched the forums, but I have a question about number 3. Is it really as simple as running a wire from the engine block to the frame of the car? I've seen pics on different websites but I'm confused. If anyone has a clear pic of this wire on a 1st generation XB, I would really appreciate it.

Thanks in advance.

1) alternator positive to battery positive, 2) battery negative to chassis, and 3) engine ground to chassis.

hmmm... my alternator is connected to the negative battery terminal....

 

Yes. It really is that simple. I did two of them, passenger side and drivers side (4AWG). When doing the big-3, don't remove the existing wires... keep them and add to what's already there.

 

So how important is the engine ground? You just find a point on your engine to ground to the chasis? Is it from the alternator ground? Anyone have pics?

 

I don't have any pictures as you're looking for the 2nd gen xb. The ground point on the engine can be any point of metal. Generally most engines already have a solid ground point to utilize... they are generally grounded with a very weak lead is all. The importance of where is very minimal. You might be able to find a few big3 shots of tCs and take the idea from there.
