Earthing kit... worth it?

[Mr Charisma]

Make your own mate.

Aluminum rail
Short run of 4ga cable ( about a meter )
4-5meters of 8 ga cable splits into 5 runs
5 Bolts
10 8ga terminal connections
2 4ga terminal conections

My left over one was out of a car with a big stereo but you can never have too big a cables. When I finally get around to putting it in ill take some piccies and show you.

You can actually get your own. Just go to Jaycar. Buy the thickest Oxygen Free Copper inslated cables you can afford and 8 pairs of lugs for a variety of points.

If the engineers designing the electrical system thought that in factory form the car needed it, they would have put it in.

Like the other guys said, large current aftermarket stereo systems can benefit from it, but I wouldn't bother with a grounding kit and If I did I'd make my own for a fraction of the price that those aftermarket companies try to charge using large gauge wire & a distribution block of some sort.

I don't know if I ever told you boys the price of the OEM Mitsu ones:

MZ606789EX - Earthing Cable Kit = A$188.00

And they'll allow you to ground 4 points only.

better way to stop the dimming of stuff and give you car better eletricals install high farad capacitors. they will stop the voltage drops and dimming of lights and what not when using windows/ subs/ anything that will spike your electrical systems.

also why use 0Guage wire when are you possibly gonna run over 100Amps threw that cable? if so you will flatten your battery in like 1hour depending on the amphours of your battery. ie 100Amp hour is 100 can flow for 1 hour before its flat. or 1 amp for 100 hours. and so on depending on your battery i don't know what the CJ's have i haven't looked at it. but i doubt the in cars are i think sealed led acid battery s so they lose volts as they flatten so it will flatten alot faster.
why cant cars come with lithium battery's they are better they run full volts till they are dead.

someone should so buy the largest lithum batteries they can find and make a 12V system out of them.

Got mine from Motoquipe westfield Burwood for $29.95 comes with 5 4ga cable, gold plated connector and battery terminal, works well in my 15 yrs old car (in terms of throttle responds) but hardly feel it on a new car tho....

Refreshing an old thread here, but does anyone have access to the actual instructions for install on this OEM kit? I'm wanting to know WHERE exactly on the car the 4 points are, so i can build my own kit to OEM specs...

Have a talk to BSYDE (Paul)
He did his custom and it came up awesome with 0 guage cable (I think)
It works well he said for his big stereo etc

Tell you what el cheapo me did. Go to Autobarn and buy this:



8 GA 6 EARTH GROUNDING CABLE KIT
Product Code: ARW6GK
This system is designed to enhance vehicle ignition due to improved relative voltage to the igniters and improved voltage delivery from the alternator.

Specifications:
- Enhance spark strength
- Reduce or eliminate ignition break up under load
- Increases torque
- Improves throttle response
- 6 earth cables provided (2 x 600mm, 1 x 780mm, 3 x 1040mm)

When you get it, cut it to size. Additional wiring adds resistance. Get the gold lugs from Jaycar and then refer to my document on this of all the grounding points I did... .

Won't so much help those with stereo systems but more so those who have alot of electronics around the place like MMCS

Im buying a fair bit of 0Ga and 4Ga cable soon probably 20M of both, i can always sell what i dont use, if anyone wants any(i doubt im gonna use all 20M of both)

only its gonna be red cable

[bryzabone]

Good tip ofey, that looks the goods.
Question is, where exactly on the engine/bay/chassis do mistu. recommend for earthing points.
Diagrams/pictures of where ppl have mounted earth points would be awesome!
thanks guys
@ blakey-Thanks for the offer, i'll try to find 'dull' coloured cable if i can, to better match my grey engine bay. If i cant , i'll PM you!

[FizyMo]

Any DIYs on this peeps? like what Bryan said, pics would be helpful

Thanks

[Blakey]

I even have heaps of copper bar, if people want to DIY it. (for what to connect all the cable up to.)

[ofey]

Alright it does seem that I never did a list of points to ground, so I'll do it here... .

Here's the view of the whole Engine bay:


Now working right to left as we view it:

4 points to note in this picture. From left to right as we view:
1. Original ground point
2. Fuse Box
3. ECU
4. Firewall

Now we route across with 5 cables.

1 point to note in this picture. You will see 3 blue cables going from right to left. See the distant end it's the
5. spark plug rail

One more travels below to the air intake:

6. Air Intake

The engine block itself under the cover sees 2 wires:

7.Fuel injector rail
8. Alternator (longer wire going across)

That's 4 down. The 5th one going from right to left is an original ground point you see:

9. Ground point on front left

So you need 9 cables in total and 9 extra lugs. I did it completely from the Aerpro kit. which provided me with 6 cables, I only had to cut 3 of those cables to get a further 3 more cables but needed 9 more lugs to make it work... .

very cool! as always, you are the man ofey! too bad i cant +1 anymore!

(i'll rate 5 instead!)
