Just make sure you get the correct gauged connectors with 5/16 IDs

awesome thank you! How does this compared to the stillen grounding kit? Or should it be about the same?

RMB5190 02-26-2018 10:15 AM

Should be the same. Stillen kit is the same materials + $150 lol

My apologies on getting this up everyone. Here is the way the kit is supposed to be set up. All points are circled and labeled. Blue 'mist' is there to show you how it is ran. I've added some additional connection to my TB and plan to re-do everything this winter in order to clean it up a bit. I'll make a new DIY if one hasn't been posted by then. If anyone has any questions in reference to the pics below - please don't hesitate to ask.

Still tweaking some stuff so I can keep it simple yet hit the main(?) spots

I am also a car audio nut and agree with the big three. However, from what I understand, on the G, running a cable from Battery pos to Alternator output bypasses the car's charging sensor. It senses load and adjusts alternator output accordingly (apparently to save fuel). Therefore, bypassing this by connecting alternator output straight to the battery will keep the system thinking that it only needs to charge at a lower voltage and the battery will not get charged properly under load.

Someone can chime in to correct me if I'm wrong.

Just to throw it out there. I would agree. I wired mine up this way, and let my radio play for about 20-30 min just sitting in the car without the engine running, and my battery died.

For the Guaged connectors what would I need for the 4 AWG terminal guage. Don't I need to add 2 wires into 1 guage connector like the first thread on this DIY?

Sorry should've been more clear - Yes 4AWG for where two wires join but the actual opening (where the screw threads through) should be 5/16.

Example: 8AWG

4AWG:

Different gauge size, same hole opening size. Hope that clears it up.

Haha its all good, I figured it out and knew I was an idiot. How much of the wire did you strip off to connect the guage to the wire?

RMB5190 03-07-2018 01:30 PM

¯\_(ツ)_/¯

Not sure, maybe .5 - 1 ''?

Just cut your shrink wrap long enough to cover any exposed wire and still cover the connector's krimp area.

Sounds good thank you :)

No problem guys!

I'm just now starting to do this type of stuff to my car as I just bought it about 3 months ago. I know this is thread is about 6 years old but great write up man! This helps!

Now that the DIY is fixed (photobucket block) & I've added my photos, a new, separate DIY is hardly necessary given how well this one was done.

Do you twist the two 8 guage wires together where they meet for the 4 guage connector?

RMB5190 03-13-2018 03:04 PM

I would so that the connection stays solid. I twisted, stuck in, crimped, heat wrapped, electrical taped all my connections; in that order.

Is electrical tape needed? Or would heatshrink just be enough?
