Aftermarket Adapter Recommendation Instead of cutting the factory plug, use a Metra 70-1761 or Axxess TYTO-01 harness adapter. It will convert the 86120’s pinout to universal colors (Red=Acc, Yellow=Battery, Black=Ground, etc.). Final Tip: Since “86120” is a part number prefix (e.g., 86120-0C020, 86120-33220), always double-check the specific suffix. For example, Lexus RX units may swap the illumination and mute pins. If possible, search for “[your full 86120 number] pinout” before wiring. toyota fujitsu ten 86120 wiring diagram

This is a common request for people installing or repairing a Toyota navigation or audio unit. I cannot display an actual image or PDF diagram, but I can give you the standard industry pinout for most Toyota/Fujitsu Ten units (models like 86120-xxxxx). This is the information you would find on the diagram. | Pin | Wire Color (Typical) | Function

If the unit won't turn on, check pins 4 (GND) , 19 (Accessory) , and 1 (Battery) . 3. 16-Pin Auxiliary Connector (Speed, Reverse, SWC) This smaller plug handles vehicle data and controls. It will convert the 86120’s pinout to universal

  1. “The problem is that the game’s designers have made promises on which the AI programmers cannot deliver; the former have envisioned game systems that are simply beyond the capabilities of modern game AI.”

    This is all about Civ 5 and its naval combat AI, right? I think they just didn’t assign enough programmers to the AI, not that this was a necessary consequence of any design choice. I mean, Civ 4 was more complicated and yet had more challenging AI.

  2. Where does the quote from Tom Chick end and your writing begin? I can’t tell in my browser.

    I heard so many people warn me about this parabola in Civ 5 that I actually never made it over the parabola myself. I had amazing amounts of fun every game, losing, struggling, etc, and then I read the forums and just stopped playing right then. I didn’t decide that I wasn’t going to like or play the game any more, but I just wasn’t excited any more. Even though every game I played was super fun.

  3. “At first I don’t like it, so I’m at the bottom of the curve.”

    For me it doesn’t look like a parabola. More like a period. At first I don’t like it, so I don’t waste my time on it and go and play something else. Period. =)

  4. The example of land units temporarily morphing into naval units to save the hassle of building transports is undoubtedly a great ideas; however, there’s still plenty of room for problems. A great example would be Civ5. In the newest installment, once you research the correct technology, you can move land units into water tiles and viola! You got a land unit in a boat. Where they really messed up though was their feature of only allowing one unit per tile and the mechanic of a land unit losing all movement for the rest of its turn once it goes aquatic. So, imagine you are planning a large, amphibious invasion consisting of ten units (in Civ5, that’s a very large force). The logistics of such a large force work in two extreme ways (with shades of gray). You can place all ten units on a very large coast line, and all can enter ten different ocean tiles on the same turn — basically moving the line of land units into a line of naval units. Or, you can enter a single unit onto a single ocean tile for ten turns. Doing all ten at once makes your land units extremely vulnerable to enemy naval units. Doing them one at a time creates a self-imposed choke point.

    Most players would probably do something like move three units at a time, but this is besides the point. My point is that Civ5 implemented a mechanic for the sake of convenience but a different mechanic made it almost as non-fun as building a fleet of transports.
