I'm in the middle of doing this to my charger. There's an awesome write up over on LX forums for this. Here's the link

Should be easy. I've seen the hood popped on some chargers and it looks pretty straight forward from what i can remember.

my car was so easy to do big 3 on. I could have done it in 3rd grade.

Vehicle?

Mercury Grand Marquis.

battery to factory ground = 4 inches.

alternator to battery = 1.7feet

engine to factory frame ground = 9 inches

I thought the battery for the Magnum was in the rear of the vehicle?

From what I know it should be, it definitely is for the Charger.

I could've sworn I posted once.

So to do the big 3 your positive run from your + on your battery will be however far away the battery is from the amp.

The big three for them goes like this.

1. You usually do Battery positive to alternator, but there's already 1/0 gauge there so there's no reason to upgrade.

2. The battery negative to ground. All you need for this is 12' of good 0/1 wire and a new battery terminal.

3. Shock tower to the bell housing (by the engine bay.) It took me forever to find this, you'll need just 24' of 0/1 gauge wire for this. It's down in a tight space, so patience is important.

When I get all my wires in within the next few days I'm probably going to do a write up over at LXforums.

I personally don't ground to the frame, I ground to the battery (which means run another run of whatever your power wire is).

What are the positives of that? I know it's possible but I don't think I've seen it done before.

Less resistance. Lower voltage drop. Looks cooler to have more wire (lol).

Haha I might have to try that. I'm waiting on all my Knukonceptz wire to come in, wouldn't mind using it all up.
