    Thanks for the offer Eric. Sorry I did not get back to you on that message. I only needed one module and had someone offer to sell me a single module.


    Another update:
    Earlier this morning, I jumped into the car to take it to the DMV.

    I started it and it immediately died. I assumed it was the battery, but the code came up as p3191. I looked online and it had something to do with the throttle plate sticking.
    I went ahead and cleaned it according to BobWilson's DIY.

    I started the car and got it to stay on, but it idled rough. Really rough.

    I turned it off and began checking under the hood. I found some rat droppings and the connector to the right-most fuel injector chewed through.

    So now I need to repair the connector or replace the harness. Replacing the harness looks a bit more involved and expensive than repairing the connector.

    The trouble with the connector is that the wire is broken right at the female end.



    Damn rats!

    In the back of the wiring diagram manual (techinfo.toyota.com if you don't have it) there's one section identifying all the connectors by a letter-number code and a picture, and another table from letter-number code to Toyota part number for the connector shell.

    You probably don't need the connector shell, but it might save you some time to get the right connector terminals that go in it. That way you're not trying to dig out some already-crimped old terminal that's been chewed off right at the end, and trying to somehow reattach wire to it. Your Toyota parts-counter person can cross-reference from the shell part number to the terminal part number.

    They can sell you the proper terminals pre-crimped to a short length of wire so all you do is cut the old wire back a bit and splice. The pre-crimped wire will be the wrong color so it will look a bit goofy, but it's easy.

    For some reason my Toyota dealer won't sell me plain terminals, uncrimped - though I can buy them at the local indy auto-electric shop, and when I ask where they get them, they tell me the Toyota dealer. Must depend on whom you know.

    Rats and mice like to chew wires, because mechanics/electricians hands smell like whatever they had for lunch.
