DEI 791xv, 2004 Taurus SEL

DEI 1100F.We finally were able to get it but we had to use an awl. If I'm looking at this correctly then it does look like those wires run through some shrink tubing to a bright green plug. The plug would be much easier to get to than the connector on the ring. I'm guessing the only reason why they make you remove the ignition switch is that the color codes change from time to time. Other than that It would be much easier to just grab them underneith the dash.

By the way, while we're on the subject of remote starters, where do you guys get the tan / YELLOW Tach wire at? Can we grab this at the tach itself?

best place for tach will be at a coil in the engine bay.Shaun, we are the same height, that is neat!

We're having trouble with it remote starting. Here is what happens: 1. We press the button on the remote twice to remote start. 2. Car starts and runs for around 5-10 seconds and then stops. The 1100F bypass is flashing 3 times and that's supposed to be correct. However we also noticed that the airbag light in the dash is flashing once, then 8 times. Not sure if this is a seperate problem or not. We tried to teach the tach by pressing the valet button, but the LED does not light (we held it for around 1 minute). We also tried to switch it to tach threshold on but the same thing happens (starts and shuts down). Any ideas on what might be causing this to act up this way?

Me and some other guys here have had bad luck using the tach wire from the ECM on certain Fords. Try going to an injector wire or a single coil once and then reprogram tach. Use any wire thats not red...Mike M2

Yes that's what we're doing, we're using a single spark plug wire. Turns out the airbag light was coming on because the radio was disconnected. The 791xv wouldn't program the tach wire because the valet switch was bad. We'll pick up a new one tommorow. The only issue that we're having now is that we can't get any of the door triggers to work :( One place tells us they are positive. Another place says they are negative. We tried both (purple and green) with the diodes but we still get errors from the 791xv when we test either positive or negative :(

Well that's the thing, one place say's the ign 2 is a BLACK/ lt. green, another says it's gray / YELLOW. BOTH drop out during crank So are you saying that both of these places are wrong?
