DEI 791xv, 2004 Taurus SEL

Has anyone worked on a 2004 Ford Taurus' door locks? What type do they use in this car, 3 Wire Negative, 3 Wire Positive, 4 Wire Reversal, ETC... ? Also, we need to diode isolate the door triggers. We were told by several different places that they should be 7 amp diodes. We looked all over but couldn't locate any. Does anyone know where we can find these at? Thanks.

The locks are neg type.

1 amp diodes are fine. Look for 1N4001 diodes

OK thanks. I couldn't find a wiring diagram of the 3 wire negative, so I photoshoped the picture below. Does it look like it's wired correctly? Also, which direction does the diode band go? Toward the aftermarket alarm trigger wire, or away from it?

Don't know what alarm your installing, but relays aren't needed. Just connect the negative pulse outputs of the alarm direstly to the pink/green and pink / YELLOW wires in the car, drivers kick panel. Also, you can use the dome light wire for door trigger if you wish, it's a positive BLACK/ blue also found in the drivers kick panel. Beware tho, it has a long dome light delay when arming...Mike M2

Directed 791xv. It mentions viewing techtip 1041 which, saddly, we don't have (can anyone share this with us?). We were told by others that it needs relays and obviously we are concerned about burning something out without them. I guess techtip 1041 goes into this further.

OK we were able to locate a copy of TechTip 1041 and it does indeed verify that a relay is not needed, and to think that we've been going without this feature all this time. Oh well, better safe than sorry. Thanks Mike M2 for bringing this to our attention :) We just need someone to tell us what direction the diodes should be facing for the door triggers and we should be set. Toward the aftermarket alarm trigger wire, or away from it?

We're using a DEI 791xv with a 2004 Taurus SEL (has both keyless and Securilock). The 791xv has two wires that tap into and control the factory alarm. The light GREEN/ black controls factory disarm, and the GREEN / WHITE controls rearm. What wires do we connect these to on the Taurus, and where should we pick them up at? We were told that the factory disarm wire is pink/white at the generic electronic module, can anyone verify that? And what about the factory arm wire, which one should we use for that? Thanks!

We're installing our first 1100F immobilizer bypass. We have several questions about it;The instructions say "Press the programming button once or twice to select the installation type. 1= Unused Installation mode and 2= Standard Installation mode"Our first question is what is a "unused' installation?Secondly, if you look at the diagram it shows blue/white as being 'ground when running'. How do we use this, hook up a relay and have it controlled by the ignition with its output going to ground?Thirdly, how do we connect the gray/red (ECM TX) and GREEN/ red (ECM RX) wires? Thanks for all of your help with this.
