I've always wanted to run a set of grounding wires but have heard both pros and cons. I figured I could make my own and if nothing happened, I'm only out a few bucks rather than $100 plus for ready made kits. I chose to ground 5 points: Head, Body, Block, Alt body, and Crossmember. I checked each spot with a multi-meter to make sure there was an active ground.

I used 8 gauge multistranded cable and crimped then heat shrinked the connectors. Overall I'm satisfied with my results. I did just a quick check last night(finished at midnight) with the grounding adapter on/off the car. In my case the car idled smoother and the HIDs were brighter/crisper. The engine did not lug or slow down when the HIDs are turned on. Now take this as you will. I do not plan on dyno'ing either. Just something I did cuz I'm crafty and cheap

Here are the pics

Body. I chose this spot as there is a group of wires.

Nice job!

 

whats the L bracket made of???(the one on the battery)
looks sweet, makes me want to do it tooo!

 

My battery is in the trunk...how the hell can I do this? Stable idle sound like a good thing to have :-)

Great write-up, thanks a lot!!!

 

i only see 4 wires attached to your battery bracket. you said you used 5 points. where is the 5th attached? did you run it in tandem with anther wire?

home many feet of wire did you need?

advise, thanks.

 

Sorry to hijack but what are the cons to running a grounding system? I have only heard that it might reduce current drag to create a more stable idle but never heard negative consequences except wasting money.

 

grounding kits are a waste of money

 

Waste of money, time, and adds additional weight. Look kinda cool though.

 

The con to a grounding kit is that it does nothing but add a bunch of wires to your car. You have a better chance of getting more horsepower from a carbon fiber hood than you do a grounding kit.

Also, this belongs in electrical.

 

That's what I figured, just checking though.
