DIY: Groundwire Kit - Page 4 - Toyota Yaris Forums

Black Yaris · 11-04-2006, 12:41 PM

so, I going to do a DIY ground kit... I was just going to buy some bulk 4 or 6 gauge car stereo wire in blue to match my theme, and all gold terminals. How much, do you supose should I buy of the bulk wire? I planned on using a gold junction block terminal, normally used for car stereo power wire. anyone have any better sugestions, or comments... Oh yeah there will be pictures for the whole thing...

If I'm right it basically hooks up to both the positive and negative terminals of the battery to better regulate and stabilize power. Not sure if it'll add increased performence, but might make electronics work better. Honestly it's considered by almost everyone in the automotive field as a bling item and nothing more. Never now though. If it's cheap then try it and let us now.

Will do,might be about 7 days before I install.

I was hoping to do another mod this weekend and write up a DIY, but it looks like I may have to wait until next weekend aswell.

We are looking forward to your comments!

I'm having a tough time with mine x__x

I can't find anything grippy enough to hold that cylinder thing so I can stick the screw up it.. It seems to toughen out 3/4 of the way there and I just don't know what to use to hold it down :|

What'd you guys do?

You need to take a small flat head and clean out the grooves.

i believe there is a difference between stereo wire & power wire... i could be wrong, but im pretty sure i was told that by an electrical engineer once...

not sure if it makes a diff on this or not...

07WYarisRS · 11-06-2006, 05:06 PM

No difference really as long as it's power/ground wire.
There are differences between audio/speaker wire and power wire.

Most power wires are aluminum, alloy or silver speaker wires are usually copper.

I have bulk spools of actual 8 gauge ground wire, The only difference really is the ground wire is braided for strength and not covered. the 8Awg is round twisted and appears to be aluminum, the standard 8 gaauge if flat braided wire also appears to be aliminum.

Good to hear. Hope you guys get yours soon.

I ordered from them about 2 weeks ago,got it last week,still need to install it,I aslo ordered a voltage stabilizer,like $75.00.

let me know if the adapter oart of the ground wire kit works with the tanabe strut bar. It looks like the strut may be blocking the location because it sits pretty low and close to the battery. It's the only thing holding me back from getting one.

Yaris-TJ · 11-08-2006, 10:20 AM

have you guys noted a performance change? is it worth?

eco · 11-08-2006, 11:37 AM

Itsmydaily,Ill let you know,it looks like it will be tight,but Im waiting for the voltage stabilizer now,so i can do them both at once,Ill tell you in about 3 days.

Voltage stabilizers are a bit overkill but can help when compnents drawing gobs of raw power off the battery are used. All cars have voltage regulators built in the alternator and most have secondary regulators under the dash for ECU and fuse pannel power...

grounding kits don't hurt at all but they do very little.

IMO people that install grounding kits and can emidiatly fell a boost in HP are completly full of it !

On older cars they tend to help more when corroded grounds and rusted pannels are present but with a new car or even a couple years old, Any gains are very VERY small.
Also many grounding kit connections are pretty much useless and people tend to take them over the top. Like grounding the valve cover.... Keep it simple. Every ground does not need to run directly to the battery. Ground can be run in series. 4 connections to the battery is all you need. One to the fire wall, one to each strut tower or inner chassis. from these points you run you other grounds in series.
The most efficient grounding kit runs large, clean grounds to factory ground points like places where the OEM harness ground connect to the chassis, isolated throttle body or places that have large gasket areas with few fasteners or where corrosion can come between contacts such as alternator brakckets etc.
Grounding the valve cover, head, and block as well as other components on the engine is not needed. The head and valve cover are well grounded with MANY fasteners.
Anything larger then 8awg wire is overkill. Factory uses 12 or 10 AWG in most cases.

I've been making, installing and selling ground kits for years for Bikes ATV and car, and out of the hundreds I have sold and installed I have never felt any seat of the pants gains like most people that install them do. LOL

The two grounds on the automatic Yaris are
#1 8awg from battery to left strut tower
#2 8awg from abttery to transmission

Wires that should be added
ground from battery to firewall (next to ECU/TCU)
ground from battery to right strut tower
From these points you can add grounds to
alternator bracket/AC unit
exhaust
throttle body
cylinder head

There is no need to add a ground to the transmission or left strut unless the Stock wires are removed. There is no need to ground the coild because they do not ground to the valve cover.
Also there really is no need to remove bolts and nuts to install a grounding kit on the yaris.
Removing bolts like the valve cover, manifolds, engine covers and throttle body etc can lead to oil leaks and air leaks not to mention over torquing them can strip holes/bolts, create stress cracks and break the cheap cast parts. The best method is to use existing bolts and holes available and in most cases a nother nut can be added to an existing bolt with threads to spare.
For instance
Alternator bracket has a pre drilled/tapped hole
Throttle body bolts can have a second nut added or use the waterpipe bracket bolt
lower ECU bolt can have a second nut added
firewall has unused studs
right strut tower has pre-drilled /tapped holes
Even the valve cover ground if you want to add one just pop off the cover, slip the ground over the plastic cover stud and put it back together.
This way the dealerships can't give you a hard time for removeing bolts and nuts to install anything.

The wiring kit like the one I made on my Yaris has all the ground in the kit coming from a central location on the firewall. I kept the OEM grounds on the Left strut tower and trans,
Battery to firewall stud. All wiring is using 8 awg copper high power and gold ring terminals.
Firewall to cylinder head
Firewall to exhaust
Firewall to throttle body
Firewall to right strut tower
Right strut tower to alternator bracket
Alternator brackt to AC compressor
