Any update on the terminal extensions? I will be looking to purchase some in the next couple months and I like your design.

Working on it. The problem I have always had with making those is that the buyer needs to figure out how to modify the ground cable that runs from the negative terminal to underneath the intake manifold. It currently is crimped to the battery terminal and would need to either be modified by clipping off the negative terminal post clamp or removing it completely and crimping on a new ring terminal.

Agreed that is an issue for most. In my case I already installed a new terminal end and am using a military style connection on the negative side. Hoping to get the extension specifically for the positive side to allow its use. Let me know if you need a tester or anything. Would love to figure something out.
whats the benefits of these kits?

Typically, these upgrades replace aged, corroded connection which will result in more consistent battery voltage. Current flows along the outside of a conductor, so any corrosion will effect the ability for current to flow efficiently. The cable I use is tinned coated and is very corrosion resistant. I also use adhesive lined heatshrink to seal the connection between the lug and wire.
And not to sound like an idiot, but what does higher battery voltage net you?
I think that the main benefit of these are if you are going to forklift the soundsystem out and put in a new system. You'll require more grounding to support the higher supply from more voltage on the hot leads. I'm still considering upgrading the stereo so I bout these 3 cables. If you are not loading up on current draws that go through the chassis, then no real need that I can see.
It should provide a better optimized electrical pathway, allowing your system (charging and grounding) to function at full potential. The corrosion-free, thicker gauge cables helps minimize signal loss. Corroded terminals (plus thinner gauge wire) increase electrical resistance, potentially starving downstream devices of adequate power.
You'd definitely notice the benefit when adding a car stereo amplifier, but you might also find your vehicle performing better too. ...especially so if your OEM cables/terminals are super old and crusty.
Not a direct comparison for the 100 series, but I built a set of thicker gauge cables for a 2007 WRX. The engine performed noticeably better after install. I'm unsure if it was a hotter spark, more juice for the fuel pump, or ???, but the car really flew after the upgraded cables were added. The upgrade was done for stereo/amp reasons, but there was a profound and unexpected performance bump too. YMMV
I don't overland camp or off road so I don't always think along those lines. Those guys would benefit from this as well. If you add things like Fridges and other electrical loads like the Stereo with amps and what not, then increasing the grounding helps a lot. When you increase hot lead loads on the electrical system, you need to beef up the ground side as well to handle the load.
Great info thanks guys.
This kit was top notch, some photos below. I decided to replace these mostly because I installed a winch and was on an electrical kick. Cleaned up AUX power setup and added these ground cables.
The thick cable from the engine hoist hook seems to be best run towards the front and then looped back around. The angles looping it back the other way like OEM seemed to bendy for the cable.
I'm looking forward to testing the winch out and seeing if lights still dim, or if there is any affect worth noting with the upgrade. Maybe more consistent charge voltage, who knows. I will say my OEM cables were a bit crusty and starting to green so it was worth the quick and easy upgrade.
Battery to fender. If you have a larger terminal mount make sure you request it
Engine hoist to wheel well. Make sure you angle the cable so it doesn't put pressure on those other small wires or rub on timing belt cover
>> @Fourrunner is this what you had in mind for routing?
Firewall to intake. I kept OEM because IDK where it goes and seems fine either way

That routing works! Looks good!
Right one...... On the firewall cable, I wasn't sure if grounding to the intake manifold like that is logical. Is it aluminum, does it provide a ground....IDK. I'm going to poke it later with a multimeter and see if there is continuity to ground.
@Fourrunner - Are these still being sold? Do you have a link to a webstore or do you take payment via Venmo / Paypal?

Yes, I still make them. I'll message you!
