Does anyone know the style of connections used in the fuse block?

    Out of curiosity, as the title states. I'm talking about the crimped connectors that connect wires to the relays primarily, and secondarily the fuses.

    I assume maybe they are Pack-Con or whatever, maybe even ISO 150 or something.

    Maybe a long shot, but with the plethora of tech info on here, I thought someone might know. Had a couple ideas, but not sure how feasible they are.

    Yeah, factory fuse block. No pics. I haven't pulled any out of the fuse block, and I might not be able to figure out how unless I knew what kind they are.

    The FSM might help, I'll have to do some digging.

    I'm looking for the actual internal connectors. As in, the little metal/brass/copper crimped contacts inside the plugs. For example, the item that the relays plug into in the fuse block, that are crimped to the wires that go out to the controlled device.

    It looks like I'd actually be looking for the contacts for the plugs that snap into the fuse block, not the ones inside it. Not sure yet, the FSM will help me understand that.

    It's probably a dumb idea, but we'll see. :)

    Well, I think the FSM told me my idea is not worth messing with. Too much of a rat's nest, and too many connections. :)

    Not sure exactly which terminals you are looking for, but if you are talking about the mini blade fuse connection terminals, I believe they are refered to as 'Pack Con II'. I just placed an order yesterday so once they're in I'll let you know how it turns out.

    Thanks! Yes, definitely let me know! :) I am looking at the fuse blade connectors, and possibly what connects to the internal bus of the fuse block. I can't remember off the top of my head, but any info about the blade fuse connectors would be a big help!

    Pack Con II terminals are a fail. Thought maybe they would work with a little persuasion, but they just flat out didn't work. Looking at the installed terminals I think the link below actually carries the terminals we're looking for (second to the bottom):
    http://eagleday.stores.yahoo.net/bladeterminals.html

    The second to the bottom I'm about 95% sure would work. The good thing about these terminals is that you can buy them each v. the others that only come in a pack of 10 or 24.

    $20 later, I've given up on the blade fuse and moved on to to the female pal fuses idea for the HID conversion. There are two blank fuse areas with powered spades on one side already, and the blank ports are far easier to access so, this will save some time and rigging.

    Thanks for the help! I have to look at the wiring diagram again to see if the wires come directly off the fuse, or the internal bus. I *think* they come off the fuse, because the fuses are after the relays and such.

    I am not sure if I am going to pursue this or not, but if not now it will be very helpful in the future. I haven't tried to pull apart the box, so not sure how much work that entails.

    Thanks for the link to the wiring diagram. It's for the older trucks, but I haven't seen anything like the wiring part numbers in the newer FSM--so that will be a big help!

    It's all 3, actually! The power goes from the battery to a distribution bus, through the relays, then the fuse, and then out to the lights.

    I just can't remember if it buses out from the fuses to the lights, or goes directly from the fuse. I am pretty sure it goes directly from the fuse. There is no connector listed for the lights connection, so I don't think it goes into a plug. I do seem to remember a bus somewhere other than the battery though. I'll have to dig through it.

    How hard is it to get the fuse block open?

    Page 6 of the overall wiring diagram details the headlight wiring circuit. HI RH and LO LH look like they go directly to the bulb, so the fuse connectors should work.

    HI LH and RH LO go through an internal bus after the fuse to provide in-cab hi beam indication and fog light relay activation. I'm not sure what that looks like, as it's not on the connector list (I've searched a lot). It might be a big plug connector to the box, it might not. It doesn't indicate any plugs, so I'm assuming there aren't any. The plugs I've seen for the fuse block don't have the circuits listed in them.

    So, I either abandon the project, or I have to do some discovery work. I'm not sure I want to disable a two-year-old vehicle due to discovery-gone-awry! :)

    Wow! Thanks for those links, the picture of the bus connector really helps.

    I am replacing the fog lights with auxiliary lights. It would be kind of nice to do the ignition hot fog circuit, and redirect it to a rear fog light I am installing (instead of having to cut into the fog light plug).

    How long did it take you to do the fog modification, and what did you use to make the Toyota connector removal tool? I think I have some small long screwdrivers, would those work to remove the fuse block?

    It still looks like a lot of work, but it might be worth it yet.

    Good to know. I have some picks that would probably work too, then.

    I figure I have 3 options to use the factory fog switch for my rear fog install:

    1) Connect to the factory fog switch in the dash with an independent circuit
    2) Switch a relay with the fog light circuit (cut the plug off the driver's side fog light wires and run back to the relay)
    3) Power the rear fog with the now-unused factory fog light circuit: i.e. cut the plug off a fog light and splice in a wire to the rear fog light.

    Maybe with this, I can do this "anytime fog" mod, and while I've got the fuse box apart, I can run a wire directly from the fuse block back to the new rear fog light. That would be the cleanest way, and not use up power, fuse & relay space on my aux. fuse block.


    ETA: What about the terminals for the bus connector? Are they the same as the mini fuse connectors linked above?

    Also, what about the relays? There is an unused relay in the corner of my fuse block that has an ignition hot source. I can think of a use for that, too (low power). Would one of the connectors on that page work, too?

    LOL this gets expensive if I have to spend $30 for one contact, though...

    OK, I was looking through the wire repair manual you linked to, and there are a few candidates for the connections in the fuse block.

    Do you have ideas for which is which? Is there somewhere in the 400 pages I mostly scrolled over that details it?

    I probably would rather have one continuous wire, but rather spend $5 on a repair wire than $30 on a bulk pack of connectors.

    Maybe Digikey would have the connectors in smaller packs or cheaper.

    I am probably looking for:

    -Bus connectors (probably same as fuse?)
    -Fuse connectors
    -Relay connectors (maybe making use of an unused relay slot)

    OK, thank you for the help. I won't be able to actually work on it until after Thanksgiving.

    Hopefully it will all go smoothly! :)
