    BR-3 from www.obddiagnostics.com is $88 , USA includes delivery ($98 USD All other countries)

    The interface supports OBDII protocols commonly used in US vehicles: VPW (General Motors), PWM (Ford), and ISO9141 (Chrysler, Asian, and European), and ISO 14230 protocol (also called Keyword 2000). (It does not support the CAN interface)

    Free software is for 32 bit Windows operating systems, such as Win 95/98/ME, or Win NT/2000/XP. Screenshots here: http://obddiagnostics.com/ScrnShot/Winscreen.html

    The OBD II standard requires car manufacturers to include a connector to hook into the system within three feet of the steering wheel inside the car, all you need to do is look underneath your dashboard. I think the Explorer has it just to the right of the steering wheel. Here is a picture of the connector:



    (this one is from a 98 Jeep, but yours should look about the same)

    very cool thank you for the response, when i get a chance i'll check that out

    and another thing, what exactly can you control with this thing, i know you can monitor tons of stuff in the engine, can you control your windows, locks 'n stuff?
    And can you control the stock computer control chip in the car through it?

    DAmn can you control engine timings ??? or just monitor them?

    OBD stands for on board diagnostics and its centered around emissions controls. I'd say its pretty unlikely you'll be able to control your windows or locks with it. But you can control things like timing and fuel curves, but i think its different for each make and model.

    Aside from diagnostics specific to engine and exhaust systems everything else is proprietary vehicle protocols.

    I have a VW, and I got a VAG-COM reader, that lets me do ODBII and access all of the proprietary VW stuff.

    would that include locks / windows?

    VAG-COM lets me control the different beeps my car can make when it locks, and whether the key unlocks one door or all doors. But that is it, everything else is hard coded.

    door locks and windows are not controlled by the engine control module on most vehicles..Usually in the body control module. Keep in mind there are many, many modules in newer vehicles. My Durango has 37. Door locks are usually controlled with another level of security as well.

    You could always hard wire a relay in line with windows / doors that can be controlled via pc.
