LC/LX 100 Ground Wire Upgrade (3 wires) - Heavy Duty Cables Big 3 Upgrade - 100% Copper 1/0 or 2 Awg Flexible cables - PET Sleeve - Glued Heat Shrink

[BnvS]

Greetings, On Sale is an important upgrade for any LC/LX 100 series SUV. This is especially true for anyone going up in age as the Ground cables may be showing their age. This upgrade will help with improved grounding necessary for all your vehicle's electronics, from Starters, Alternator, to all electrical components needed to run the car properly. This is part of the wiring kit needed when upgrading your Alternator from stock to higher Amperage Alternator. Also very beneficial high amperage power draw equipment such as higher end car audio, Audio Amp installations, trail lights/LED's and recovery winches.

Improper engine grounding can cause several failures such that may appear to be mechanical issues, ranging from the engine not turning over, starter clicking, alternator not charging properly, electric components acting up, to transmission not shifting properly.

BTW I also sell the an Alternator upgrade cable as well 3-to-4 pin connector at on this post.

  • More than 25% (2 AWG) / 50% (1/0) bigger than the standard OEM style cables vs Toyota OEM ground wires
  • Resistant to abrasion, battery acid, diesel, engine coolant, engine oil, ethanol, gasoline, power-steering/transmission fluids,
  • Withstands Extreme temperatures (-50C (-58F) to 105C (221F))
  • 1/0 = 975/30 # conductor strands
• High Quality Tinned Plated Copper Terminals Lugs
  • Hydraulic Pressed Terminal Lug Crimp - Crimped twice per Lug
  • Tinned Copper for high corrosive resistance to oxidation/corrosion to the elements
  • Lug are designed to increase surface area contact with terminals studs and to improve metal to metal contact and efficient heat dissipation
• Marine Grade Glue lined Heat Shrink (Glue Lined for increase water resistance)
• PET Braided Sleeve Cover for added abrasion resistance (***Cable PET Color may change***)
• Made in USA (With US and Imported components)
• Wires specifically and sized to fit the 100 series Land Cruiser/LX470 (1998-2007)
• All cables are clearly labeled and marked for ease of installation (please refer to installation guide)
• This kit is designed to minimize wire & terminal lug oxidation & corrosion increasing your vehicle electrical performance

Installation -

• Keep existing Ground Wires in place and install the new ground wires over them as shown in the pictures.
• Using the existing vehicle Grounding Wires bolts points shown with Red Arrows in the pictures to install the new Grounding wires
• Use 10mm Socket to remove existing M6 bolts and clean the metal exposed area of any oxidization (Rust) of the vehicle metal surface
• Clean the all Ground wire bolt area with wire brush or similar and ensure body metal is thoroughly cleaned before re-installing all Grounding wire
• If available apply dielectric grease or battery terminal protector to prevent oxidation/corrosion around the GW bolt area
• 5-10 days after installed Recheck Ground Wire bolts are secure and have not come lose

2 Gauge Price = $75 Shipped US (Years 06-07 $85)
1/0 Gauge Price = $90 Shipped US (Years 06-07 $100)
And yes material pricing has gone up due to Tariffs

Please PM me for ordering and with any questions, suggestions or modifications. I make these on my spare time. I take my time make these cables and ensure these are the best quality cables made for your vehicle. I accept Zelle, PayPal, and Google Pay.

Thanks

Hi there, any reason the replacement alternator cable bypasses the fusible link? I am replacing my FL and I’d like to replace the alternator cables as well.

 

[BnvS]

The reason to bypass the fuse is because the routing of the Alt cable is kinda Pita if it goes through the oem fuse routing. Which is why it is bypassed with its direct fuse to the battery positive.

Just got my kit and everything is great. BnvS is great to work with. Quick reply and kept me updated on the progress of the order. Everything is as described in his post!

This looks like just what I need! Grounding cables are corroded to dust at the connections, so I don't think I'm going to try to save them.

@BnvS , is there a reason you say to install these cables on top of the old ones instead of doing a full replacement?

Aah no reason other than just keeping the OEM wire in its place. Keeping the OEM wire doesn't interfere with anything so I just kept it.

But taking the OEM wire out is okay as well.

I'm installing your kit now. I have an '07 so the cable that goes from the firewall to the intake manifold isn't going to be effective since the intake is composite. Have you (or anyone else) come up with a solution for this cable on VVTi engines?

Can you please take a picture of the section. You can likely use engine bolts around the area to ground that wire.

It's all plastic around there. IMO only potential candidate would be the upper valve cover bolt which isn't ideal and would be a serious stretch for the cable due to the twists and turns it has to make.

The factory firewall ground goes into the loom and I presume comes out here and secures to the hook. This looks ideal to me but of course would require a longer cable.

This wire circled in RED is the ground to the Engine - Firewall. If you follow it down it is attached to the engine. It was a PITA to get to.. but it can be done.. Just make sure you do not lose the bolt when you take it out and put it back in.

This is the reason I changed the location to the engine bolt I show, which in my 2000 LC was not a composite/plastic intake.

The existing wire should be long enough to get to that ground hopefully as I accounted for that possibility. Barring Toyo didn't change that location from my engine.. (which they should not, but you never know)

Let me know. Thanks

Yes I understand that is the factory engine to firewall ground. If you follow it down 2" from your red line it goes into the corrugated loom. I assume it is the same wire that comes out on the passenger side and attaches to the hook. The cable you provide is not long enough to reach that hook.

 

[GTV]

I used the alternator cable provided to get an idea of layout and length. IMO this is the best solution but I’m open to suggestions. There is no way the provided firewall to engine ground will reach this location.

Was their a solve for the later models engines with this kit for the backside engine ground? Need to order a set for my ‘07 LX470.

I made the different cable for @GTV. He has installed it and works on his vehicle. I will be making slight modifications for the 06-07 LC/LX due to the plastic intake a longer route of grounding needs to be taken.

I've had this kit for a few years now. Very happy with it.
