I have a random desire to install new grounds to the Fit's electrical system. From what I can spot, it seems there are only two grounds with what I would consider small wire for a battery ground.

So I thought I'd gather some opinions on what some good grounding points are, aside from the obvious upgrade on factory grounds and good cleaning on existing points.

I was thinking of grounding the throttle body to the engine block, considering the manifold plenum is not made out of metal. I also had thoughts of running a ground to the transmission or two, since the only ground to it is by the engine block and mounts. Not really sure what else would be a good place to consider.

 

May I ask your reasoning behind this?

It's adequately grounded from the factory is it NOT?

If you're engine starts under 200A of current, what makes you think the 40A or less of current whilest driving is too much for the grounds to handle?

Not hating, just curious why you'd add wire if it's not needed

 

someone else already ran the numbers the Fit does need a grounding upgrade, (esp for an audiophile) I'll try to find the post... in the mean time here is what blueboogers used


Just finished up my stubby battery cable to replace the wimpy stocker.

1/0 Knu Konceptz Kolossus Cable
Techflex
Two layers of heat-shrink
JL Audio Grounding Lug
Knu Konceptz ring terminal
Kicker battery terminal (to be re-badged as "NEGATIVE")

 

found it! Kinda... still looking for one with working pics.
But it might help. so here you go.

I'm doing the big 3 once i'm done with some home projects.

 

Yup that's the DIY. Did it to my car last year. Less than 5 minutes.
