Upgrading your power cables

Recently, I discovered that Dodge Chargers and Chrysler 300's have a rear mounted battery and contain a very long piece of 1 gauge welding cable as a battery + wire. You can pull this out and use it as a single run from the fusebox post to the trunk or chop it up like I did and do a mid-mount battery setup and have enough 1 gauge for all the other stuff too.

Step one is to yank out all the old wires. I removed ALL of them a year ago so the removal pics are missing. You have three main cables; one for the starter, one for the battery and one to the alternator. The alternator cable is actually two small wires together. It and the starter cable goes through a harness. Just cut it out easy and dont hurt any other wires by ripping and snatching. Do it slowly and carefully.

The new cable..


beginning the install by measuring up everything..




Use corrugated plastic loom the help shield the cable against abrasion. Tape the ends and any loose points.


running the battery + cable through the firewall..



running the batt+ cable along the outer firewall..



running the battery + cable around the driver's side..




Now that the cable has been measured to proper lengths, you can begin cutting and attaching the copper ring lugs. Try to save the original 1G lug that came with the wire. The copper ones are about 4$ apiece.

trim up the insulation and prepare the crimping tool..


my crimping tool (Harbor Freight 6 ton hydraulic press)..


smash! 6 tons per square inch..

I have made a 2 gauge starter cable also using a piece of a Chevy Cobalt batt + cable..

I had to bend the lug a little and make sure it would fit on top of the battery cable in the fuse box..

Starter cable installed on top of batt + fusebox terminal..


and now for the alternator.. I used the extra 1 gauge that was left over from mid-mounting the battery.

You must use smaller 2 gauge copper lugs inside the fuse box because they are slimmer than 1 gauge lugs. 1G lugs will not bolt down correctly to the fuse studs because they are too wide.
Here you see it bolted down on the opposite side of the fuse box..

new alternator cable...






inside the car, you see the gold-plated + & -batt terminals and the various grounds and +'s that go to the trunk-mounted amplifier and inverter..

This is my current main ground for the battery.. its the passenger seat bolt. I removed my passenger seat long ago, so its handy.


I may upgrade it further when I get some more 1gauge cable.

Nice write up! I have been wanting to replace the cables on my pgt I just got because the previous owner fubar'd the stockers when he tried to install an amplifier.

Always try to use copper lugs for joining the wires and avoid those 'distribution blocks' because they can come loose over time and cause problems.

I had a distribution block on my 94 PGT and it wiggled around causing my starter to be lazy and after some time, the connections got hot and started to melt.

Good to know. I started on making new cables out of the 4-guage amp cable he left in the car. I am replacing the alternator cable, starter cable and the battery ground to the chassis as well as the ground from the block to the battery. Its been raaining the last few days but I should have some pics tomorrow hopefully.

Upgrade the grounds by adding a fat one from the frame to the tranny also. It's good to inspect all those tiny grounds that go to the tranny from the main harness and clean them real good. I found something like four of them down there!

I did do the extra ground and the ones I could see from underneath looked in suprisingly good shape. I still havent taken pics yet. I work midnights and I ended up sleeping the whole damn day away. but I got my new carpet :-) so ill be working on her tomorrow.

Cool. When you finish up your new cables, add a photo of them in this thread. I'd like to compile plenty of different views from other angles and such. My car is far from stock, so some variety would be good.

Pics of my custom cables

I finally got a chance to snap some pics of my cable job. Let me know what you think.

another car that has great cable to steal if your too cheap to buy new is most newer BMW's. they have a trunk mounted battery also with like 0/1 gauge wiring.

also the local advance autoparts store here sell 0g battery cable by the foot for only $1.75 a foot. Its good thick stiff suff. I did my mid mount battery move with it and all my grounds and my car actually starts faster then it did before the move lol

if you want cheap cable, find a local welding supply house. they are a great source if you want to go cheap. they have all the terminals you will need also.

Stock is pretty tiny. I wouldnt be surprised if it was 8g.
I did the same project recently while im waiting on other parts to arrive but I used a fused distribution block near the firewall and only used 2g wire since the battery is in my fender.

The ground off the battery is probably a 4-6 gauge, def larger then 8.

I need to get off my butt one of these days, and finally upgrade a few on my beater 626 next. Ive been putting it off waiting to get ahold of a 110amp Milly alt.

Not really. But if you have added alot of electronics, or relocated the battery, its a good idea.
