DIY: Groundwire Kit

[OgDogg]

Well, I got an oil change today and decided to install my grounding kit when I got the car back. After taking my first ride here are my impressions. Might I also say that I was very skeptical that this would do anything for the performance.

It seemed like the rpms were much lower at cruising speeds than before which made it feel less like the car was struggling to maintain speed. It also felt much smoother shifting through the gears. No delay throwing it into the next gear. That was the most noticeable attribute. It could just be the oil change, but I doubt it. I recommend the grounding kit.

Some one told me that modern cars are grounded pretty well because I really want this but i dont want to waste my money

Well, when upgrading a bottom end car such as the Yaris it's always going to be a waste of money. :) But if you want to slightly improve things and you enjoy working on your car, go for it!

Ok, i've been into cars and electronics for years now, and I must say that after I installed the kit, I did notice a stronger "feel" to the acceleration than before. Also my transmission (manual), seems to again "feel" better, more accurate than before. I also have a radar detector that can measure my voltage, and I now run an average voltage of 14.3 volts, where as before, my car would run 13.9 volts. I believe because the negative electrons run more freely now throughout my vehicle, there is more of a balance between the stronger positive, and normally weaker negative power within the car to make all power using mechanics more efficient.

Moreover, a better electrical balance throughout the car. For $22.00 shipped, even it it's a facade, and my electrical readings incorrect, it just "feels" better.

Summary: GET IT, it's cheap, and I CAN see a difference with my volt meter!

The grounding kit replaces your whole negative right?... So you have to have one of those wires on the starter?

Excellent DIY Thank you.

diy guide said posted earlier said to keep the stock negative terminal how do you connect do did you connect the cable to the grounding kit?

I have a 2010 3-Door 4-speed auto with less then 500 miles.
I will order a groundwire kit this week.
Should I wait until after 1,000 miles (the break in period) or after the first oil change (5,000 miles) or should I install the ground wire kit as soon as possible?

I have the fuel saver magnet that covers your fuel line near the engine. That really works. I had it working with my late car (2004 Corolla S - 10 to 15 MPG extra city). So far, about the same increase MPG for my Yaris.

Hey kac!
Was this an ebay item or did you make it yourself?
Looks nice.

I did this earlier this week as well and it turned out better than I'd imagined. The DIY guide helped A LOT. One definite issue I had was getting the adapter off of the negative battery cable. I ended up sawing it off, but not before slicing my knuckles a few times trying to get it off with a wrench. This install was very easy and would've only taken about 45 minutes if it weren't for that pesky adapter on the battery cable.

Anyway, as far as results go, I can't say for sure that it's all based on the new groundwire kit, but my car definitely rides smoother and accelerates better, particularly in the mid-range RPMs. I also feel smoother shifts from my automatic transmission.

However, I absolutely have to note that part of this may be due to the fact that I had the battery disconnected for about an hour, which reset every electrical component in the vehicle (including the engine control unit). So, I would've experienced a smoother ride either way from simply resetting the ECU, but I've reset it before and don't believe the results were this drastic in the past. I haven't had a chance to see any difference in fuel efficiency yet, but it certainly wouldn't surprise me to see an extra 1 or 2 mpg.

P.S. Kac, is your air filter just laying out or do you have some strange new intake I've never seen before? I see your sig says you have a modified air intake box. Is there a DIY guide or any more info about it?

[kac]

Blacksandiegovits did it first. i just modified the stock air box.

I got the info on how to do it from another thread... don't have a link for ya sorry. search around.

Will the grounding kit be the solution for those nasty static shocks I keep getting every time I close my door?

[wsladaritz]

No birdman, it will not solve that problem :( I've had a grounding kit on for 2 years or so now I think and I still get those nasty static shocks occasionally. Not always, but when it happens IT HAPPENS. I have no idea what causes it though...

Thanks!
