I'm guessing this mod could have positive benefits over time as the body/frame settles and points of contact become corroded.

Very nice tutorial and the pictures really make the difference.
Kudos to the moderators for the Tech Article "stickys". I wish some other forums would archive the best and recurring subjects.

 

There are quite a few ******* on this site nowadays. I'm glad I don't have to moderate anymore. deeeeks. :D

 

I'm thinking about trying this on my tC, but I've never touched anything under the hood before, except to refill the windshield washer fluid. Is there anything that I should know to avoid getting shocked, burnt, etc? Also, should the engine be cold or warmed up or doesn't matter? Thanks for any help!

you'll be safer when its cold

 

I did mine MIKOCHU STYLE!!!!! Except I used a distribution block off the battery and ran 4 gauge wire to the strut towers. Then, I ran 8 gauge wire from the drivers' side to the first coil pack (and daisy chained all the coil packs together), and 8 gauge from the passenger side to the block. Take a look:

 

hey on the wire that goes to the coil, my father actually put it on a bolt thats to the left of the coil that mikochu stated. does that make a difference? i will post a pic if anyone needs to see where i put it

 

Great job I almost followed your instructions to the letter. I only differed in using a kit [you can get one from ebay for $15.00 including shipping] If I am not wrong it looks like you jumped from point to point in a daisy chain effect, With the kit I used all the connection points on the body that you used, but started from a central area, with only one wire from each start to ground point.
I think the way you did it would not give a true ground,
The kit although has no instructions at all was very easy to install with your pics.
I have noticed a gain in power & no more shocks when I gt out of the car. as for the MPG? The kit has not been in long enough to say [more to follow]
The whole job took only an hour to complete.
Thanks

Disconect the battery on the ground side it is the one with the - and is black,
not the +
Other than that a 10 milimeter scocket and some strength is all ya need. I'd get the grounding kit all of the wires have the conectors perinstalled, and precut to fit. I have seem them in blue, red, purple, green, and yellow. Also work on the car cold don't want to get burned.

mine are in black and orange in color also in two gauges 8 and 6 gauge

 

ahh, would be nice to have the pros/cons listed in the front page of grounding your car. I had to go through the posts to get a few pros

how about all the pros and cons of grounding your car?

 

great writeup, lots of good info, wish it could all be summarized someway, instead of having to read thru all the posts.

 

i think all tech post should have some sort of intro, purpose kinda deal...

 

I just wanted to let everybody know that I've released the this grounding wire kit tutorial on a new Wiki built just for Scions. The Wiki isn't necessarly ready for the public yet, but what better way to get people to contribute and add their own articles and tutorials than to get it's foot in the door?

You can read an updated and completely customizable Wiki version of this Grounding Wire Kit tutorial at The Scioniki - Ground Wire Kit

There really isn't much documentation yet, but it'll show up soon. In the meantime just look up the documentation for mediawiki.

 

I did the "mod" today. I took no time at all.

I used 4 AWG weld wire from work. I wanted 6 or 8, but 4 was in stock.
I may redo it (black was also available), I chose red, but if I ever begin with a "theme" I think it would be blue, plus it looks wierd to have red wires running to the negaive terminal.

If I switch, I will let make a post so if somebody wants red, I will send it to them.

P.s. No pics because my camera got broke on the 4th

 

Well, the red bothered me so much I already swapped it to black with blue heat shrink.

Check the classifieds.

 

When this was said, did you mean that as just another 'in general' disclaimer? or is there something particularly sensitive about grounding the alternator? (or the trans for that matter ince i've got an auto and wanted to)

 

I meant it in general.

 

im looking into re-doing mine. I had to settle with Red cuz thats ll i could find in town. Im looking for either Yellow, Clear, or maybe even Orange...

 

I did this mod this weekend in hopes to see any difference.. wether its performace, smoother idle, or throttle response.
The result? No change.
