ok, poll time those of us with ground wires. Poll Make a difference?

 

more stable current flow... maybe a smoother idle but that's it... good for people with big stereo setups (ground wires = big3)

 

Yup, i second SCI TC GUY, factory Toyota grounding is horrible, to be nice about it.

 

looks good, and I don't have a stutter in my idle any more.

 

my idle sits at 300 - 500 rpm. sounds good. espiler exhaust, sounds like a dead v8. OHH yes

 

^^ isn't that quite a bit low???? mt tC sits at 900 on the dot

 

I say you should check your wiring. It should idle at about 800 rpm when warm. You must have something wrong.

 

i remember puttin the big three on my thunderbird (which i will be seelin today and pickin up the xa tomorrow) and even on a big v8 liek that grounding kits help.... a bit ^_^

 

mine idles around 700 rpm

 

where could i pick up a set of ground wires?

 

you can make yer own

snake oil

 

I will say, I have a background in electromechanics. in my understanding in electronics. The cleaner and less resistant path you can give voltage,the better. It's not snake oil, It's basic electrical theory.

 

I have to agree. I put ground wires on mine because of the sound system. I didn't notice any other benefits from it.

 

Exactly right on. Makes idle smoother and helps overall efficiency of the electrical system. Snake oil That's funny

Mine idles in drive at 400-500 rpms. Butter smooth

 

Does installing an aftermarket grounding kit in anyway void the warranty? Does it have to installed by a certified mech? Is it better to make your own kit or buy one of the prefabs? Installation seems simple enough, just don't want any dealer service problems since it is brand new.

 

It will only void the warranty if the part is found to cause a problem. You can install it yourself. You can make your own to save money. Buying one just makes it easier.

 

there's generally less unbolting and re-bolting for a kit made by you... the big 3 will give you same results with less small wires running all over...

 

I found out yesterday at the dealer that ground wires do indeed make a difference. I took my Box in for the 5000 miile oil change and to have them check out my A/C since it isn't working. The tech opened the hood, saw the grounding kit and prmoptly pronounced the A/C problem to not be covered by warranty. The service manager told me it would be 280 bucks to do a diagnostic of why the A/C isn't working. Oh, the other reason my warranty won't cover the A/C is because I commited a moral sin and installed an after market stereo. I'll be taking it to another dealer tomorrow.

Toyota: It's more than a feeling...of having a hot poker stuck up your backside!

 

tell them that they have to do tests to PROVE the ground wires/aftermarket stereo was the cause of the problem... Magnuson vs. Moss act states that they can only void the warranty if the modification is the DIRECT CAUSE for the warranted part's failure... THEY MUST PROVE THIS!!!!
