Big 3 Upgrade to Improve Electrical System

I only have a very basic knowledge of the vehicles electrical system. Years ago, I bought one of those eBay grounding kits, added a few of those grounding wires mainly from the engine block to the chassis/vehicle body. Quite honestly it did not make any noticable difference to the performance except having some visible thick red wires when you opened the bonnet. 

I have noticed a thin grounding wire on my Aurion going from the block to the block to the chassis. There have also been a number of Forum posts e.g. dim lights where the solution has been to fix  a grounding connection.

There are a number of Big 3 Upgrade YouTube videos where existing wiring has been either replaced or retained in conjunction with an upgraded wiring using the same connections. I did note one video where the presenter reported a noticable improvement in cranking and engine start up on his old pickup truck. Checked the start up on my Aurion is totally fine in my opinion so no problem with the existing wiring for the starter motor. 

I have got a few thoughts about mainly retaining the existing ground wiring and adding upgraded wiring using the same connections. The other thought is running a wire from the negative battery terminal to the nearby chassis rail area.

Seeking any suggestions or feedback from those who have done this Big 3 Upgrade or similar.

      Front parking sensors

      We have a 2021 VX Prado with Toyota bullbar that is the doing same thing, the dealer did a patch under warranty which made no difference. The dealer now says they fixed it under warranty (by doing the patch) and there is nothing else they can do so if we want them to keep looking at it we will be paying for it. That is not our understanding of how warranty works and will be taking this matter further.

      Cruise Control Not Engaging

      Hi. My 2008 Rav 4 cruise control has not worked since I’ve owned it. When the on button on the stalk is pressed nothing happens, not green cruise dash light or anything. Previously, I’ve had a problem when the ABS, VSC and parking brake light all turned on but that was fixed by a brake light switch replacement. But the cruise still does not work. I’ve checked all the fuses and all are good. Is this a common issue and does anyone know why it’s happening. thanks

      2007 - Floor mat

      Hi. I have a nice 2007 Grande which is still in good nick, except for the drivers floor mat. Normally it wouldn't be a problem to replace the floor mat but because it has the word CAMRY embroidered into the floor mat, I would like to replace it with the same again. I'm feeling reasonably confident that a Toyota dealership would just laugh at a request for another factory one so my question is, is it even still possible to locate an embroidered floor mat for my 17 year old car? If so, where? Or is there a business that will replicate the original?

      Toyota Corolla 2012 zre152 4 speed automatransmission issue

      Hi Gary, I would suspect a clutch problem, like not fully disengaging. Maybe you aren't fully pushing it to the floor, or the system needs topping up or bleeding or both. Herb

      Toyota Corolla 2012 zre152 4 speed automatransmission issue

      Hi Toyota owners, I'm new to this forum registration. I need some advice or help as I have a shifting issue with my 2012 4 speed automatic transmission. It doesn't do it all the time but the gears don't shift smoothly specially 3 to 4 gear it just bangs in when I'm cruising and it happens more often when hot. Got full transmission serviced with Toyota genuine parts no metal shavings in pan. Changed ATF 3 times. Full major service done, 100000 KLM on car. Full synthetic oil with 98 Ron fuel. Throttle body cleaned twice. Maf sensor cleaned. New spark plugs. No engine codes. Great loss of power sometimes specially on hot days. Please help as no mechanic knows what the issue is. Thanks in advance.
