i made new grounds for my car with 6 gauge wire. can someone tell me where the grounds for the tranny and throttle body are located? i cannot find them.

i forgot to say i have a 95 1.6 mx3 automatic

just loosen any bolt on the tranny that will not leak fluid and get a good connection there, I mean there is no specific place... also same on the throttle body...

isnt there a positive and negative comin off the tranny and the throttle body? i want to ground those negatives to the fender

Dude, i don't know about all that but why don't you ground them to the negative terminal on your battery? thats what i did works great

First off, before applying these nifty kits, it helps if you know what they do,...

The only wires on your throttle body are coming off the TPS which is a self contained insulated unit. Grounding it is useless, and messing with the wiring is a baaaaad idea. Tweaks the CPU & can mess up your eninge something fierce.

The tranny doesn't have a pos/neg. Like the TPS, the wires that DO go in/out of it should not be messed with unless you like walking. Now stock, it should have a bonding strap somewhere in the rear of the engine compartment just to provide a more solid ground from the eng./trans/ to the body. If I recall correctly ist on one of the motor/trans mounts. Replacing that bonding strap with a heavier cable will provide a better ground.
A good way to do this without crawling around under the car is to runa split cable off the neg side of the battery to a good grounding point on the chassis.

How many wires basicly run from the neg terminal now? I just got a kit from ebay and I was wondering. Can't you just replace all the wires that already run, or is the point to add more wires to more grounding points...

has anyone with a mx done this mod?
also if ur inressted pick one up on ebay

I'm not 100% positive, but i'm pretty sure those "mazdaspeed ground wires" are a complete scam. All the dood did is take background images of MS cars and put some generic car stereo wires with a couple of mazdaspeed stickers on the collector. waste of money, esp for the ridiculous shipping they want for a few wires.

You can get your own "mazdaspeed groundwire kit" for $24.99 at walmart's stereo section

Mine works good in my MX3

lol yea he is charging like 18 bucks for shipping, whata ****ing ***o

A cheap source of super heavy duty ground wire I used on my car:
Went to walmart got a cheap set of jumper-cables $7.00 ,sometimes you will find diferent colors if thats important to you?, these cables suck as jumpers but are 10x heaver guaged than you need,but hey more is better, I cut the clamps off ,cut the lengths I needed, then soldered (use electronic soldier) copper eye loops on the ends.
