Ok, installing an Omega RS-7K2 remote starter. Using a DEI 555F to bypass. Having a problem. Cannot locate the DK GREEN/ Purple wire for the factory alarm disarm. It is not anywhere on the left side of the vehicle. I have spent 3 hours lookinhg at every wire and it is not there. What the vehicle does now is this. I take a key, turn it to run, wait for the alarm light to go off, then place a second key in, do the same, then place the chip of the DEI near the opening and remote start the vehicle. The car starts, but the alarm light flashes. When I try to move the chip the car will not start at all. If I go through the whole process again, I can get it to start once. So I need to know where the heck that dk GREEN/ purple wire is, and what alse I may be doing wrong.

My personal vehicle is a Sport Trac, I did not have to hook up an alarm disarm on mine, if the wire is not there (as in my case) then you dont need to hook it up. As far as the imobilizer is concerned (that is what the security light in the dash is for) You are doing it right. Make sure your connections are correct on the 555f. If it is not getting a ground from the RS unit on remote start request, that would explain your problems. What year is your sport-trac?

And clarify. Vechilce starts and runs just fine on remote start, but the security light flashes?

For the 555f I have the red wire going to a fulltime (+) supply. The blue wire (-) is being triggered off the secondary ignition 3 prong port through a relay. What I did was take the red and blue wires from my red 3 port plug and I use them to energize my relay. I then supply (-) to the 30 on the relay and pull the (-) from there to the 555f blue wire.

When I put 1 key in, turn it on until the security light goes off. Then I quickly remove it and place a second key into the ignition and do the same. Then within 10 seconds I place the chip in front of the ignition and I start the car with the remote starter. It will start but the security light flashes rapidly. It will stay running. If I then shut the car down (tap the brake, hit the start button, it doesn't matter) it will not restart no matter where I place the chip.

I may be reading it wrong, but your engaging the 555F off a secondary ignition wire?? My question is, does it engage also when you turn the key on? If your tapped into an ignition wire, then it will get power when you turn the key on. If thats the case then your computer in your truck will not go into learn mode. It would be seeing two different "codes " at one time. Let me know if thats the way you have it hooked up. Also, the "alarm" system has nothing to do with the vechilce starting. It only arms when you lock the door with the door open, then close it. My sport trac does not have that system.

My remote starter unit has a three port plug that provides an additional source incase your car has a secondary ingnition wire. It has 3 wires: red - provides a constant 12 volts used to power the relays coil; blue - provides a 500mA negative output which basically provides the same function as the 12 gauge blue primary ingition wire. It is also used to trigger the relay coil. The other is a green that is a 500mA wire that is used for a secondary starter circuit. I am using the red and blue wires to activate the relay coil and thereby suppling 12 volts (-) to the chip.

Try this then, do not have the "eye" of the 555F near the ignition switch, cycle two keys, then put it near the Ignition switch and request remote start. If that doesnt work...??? then im at a loss. What year is the Sport Trac. I used a Trilogix PKF to bypass my key. But it only works on 01.

It is an '01 as well.

That is what I have been doing. The chip is hanging 12-18" away from the cylinder, I cycle 2 keys, then bring the chip up and it remote starts no problem. I then tap the brakes to shut it down, and try to restart it and nothing. I have moved the chip all over the ignition area, but all it does is try 3 times (it does not turn over), then shuts down.

What wire are you using as the nypass module trigger ? Test this wire to ensure that it has current throughout the remote starter sequence.

On the Omega, there is a red three port that is used when you have more than 1 ignition or starter wire. Since the Ford does not have either, I am using the red (12v + constant), and the blue (500mA - trigger)on this red three port, to activate a relay coil and then running 12v (-) through the 30 on the relay to fire the 555F blue wire. The red wire on the 555F is connected to 12v+ fulltime source.

Try to direct wire the 555F, to see if its dropping out. Jeff I think is saying that your power may be dropping off during crank from your Rs. If all else fails, get a PKF. This unit doesn not use an eye, or antenna ring, it hooks direcly to the wiring coming from the lock cylinder. Next question is why are you using a relay?

Why not hook the - wire off the 555 directly to the Rs? It is an extremly low amperage circuit, less then 100 mA.
