    I noticed while flushing/bleeding my brake that the circular connector on the negative battery SAE post had cracked all the way through. I can't seem to find the part number for the harness assembly anywhere in the Toyota online parts for some reason. Does anyone have the p/n? I just hope it is still available from Toyota, as I am starting to run into all kinds of discontinued parts!

    Do NOT go to the dealship for a wire or battery terminal. They'll probably charge you $65 for it.

    Just go to the auto parts store and buy a couple chunks of large(ish) guage wire, or just some universal battery terminals.

    With these, you can just crimp the wire. No need to solder anything.

    Depending on what you're planning to do with your truck, you may want to look into the "big 3" upgrade, which is upgrading the size of the 2 main wires that come off the battery/alternator. Then you can go for a little better setup with the battery terminals. The nicer ones are the "military spec" ones:

    I use all Military style terminals. with the post .

    Crimp lugs on both ends good to go.

    I have been making all my cables for the last 20 years using short pieces of welding cable for the cost of the lugs

    Buy (Link removed, wrong product)
    Edit: You need 90982-06022 for the negative cable (Grey plastic)

    Then modify the existing cable/terminal by cutting off the clamp portion to leave a square tab with a round hole in it. Now fasten that to the new terminal with included but, and you are done. It even looks OEM!

    let me know if you need a pic of the finished product

    MikeWH- great minds think alike! After I posted my original question, I went back to the truck and took another look at the factory cable. This is my exact plan! Not sure why Toyota crimped the negative battery wire to the clamp, whereas all their other models use the terminal you point out.

    Toyota used the clamp with the bolt and nut on the positive side but had the crimped on type for the negative cable on most/many models. I'd bet the negative cable is very similar on related Toyota models like 4Runners, so you may be able to find one at a junkyard, but a lot of junkyards cut the wires to get the battery out fast. I'm sure the part number is in the Toyota catalog. I can't remember the section.

    Yeah both of my Tacoma’s that clamps has slowly failed due to cracking. I think it’s design allows over-tightening which leads to cracking. Here is a pic of what I did. I recall that you have to trim the connector with tin snips slightly since the edges of it are turned up.B77408B9-DC59-43D0-BDA7-23D908163512.jpg

    Mine did the same thing so I picked up a plated set that is built similar to the factory ones.

    Crappy battery terminals are the number one reason for dead batteries and charging issues.

    The plated ones never had corrosion build up. It helps to apply some electrical contact lubricant as well.
