I just installed a bulldog security rs82b in a 2002 f150 supercrew. Its just a basic start and stop starter. It has the ability to start with the factory fob. I did not attach the factory alarm disarm wire because i did a test to check if there was an alarm and i dont think there is.

My problem is i have to push lock 3 times to start it. Then i cant unlock it or shut it off because it disables the fob. Is there a way to make this work? Vehicle lock programming ect. Should i have connected this wire for the factory alarm disarm. To the dark green and purple wire if so will this work? Will it make the lock and unlock work or do i have to do something else? Thanks

I do not think the factory disarm wire will fix your problem. The keyless entry module does not see a need to work because the vehicle is running. The only solution is to kill switched power from the keyless entry module. Some vehcles this is possible, others are not. If there is a separate keyless entry module, it may be possible to have the GWR wire interrupt that wire with a relay. If the keyless is controlled by the vehicle's comuter, chances are you will not be able to do this.

I believe there is a separate modual for the keyless. White box on the fire wall in drivers compartment? Not sure, I think the computer also controlls it too. Dont really know. So probaby no way?

So if i can how exactly would I do this? What wires ect to use on the vehicle. The wire on the starter puts out a negative charge. Anyone done one of these before?

Using a volt meter, test voltage on each wire of the module. If you find a wire that goes to 12volts when the key is turned on, and goes to 0 volts when the key is turned off, there is a good chance that might be your wire. Cut that wire somewhere that you will be able to reconnect it if it does not work for you.

If this does work for you, wire a relay as follows. 85 to GWR (Ground Output When Running) 86 to a constant 12 volt source. 30 to one end of the wire you cut, The other end of that cut wire connects to 87A

This will allow the locks to continue to work normal? Plus when running? Sorry new to all this all info is greatly appreciated. I will have to check if that is the keyless module.

The unit I have is a RAP Module. Its a (remote anti theft personality). I believe this is the unit it has three harnesses coming out of it. Does any one have wiring harness diagrams for this? It would be very usefull seeing there is a lot of wires coming out of it. Also has any one done this before? I dont want to mess up the unit and have a problem were vehicle wont lock, unlock or even worse. Disable so it wont run.

I think it's going to be a little less complicated than all that.

Did you power up ALL of the ignition and accessory wires while doing the remote start?

One of the accessory wires should be BLACK/ green, and it will show power with the key in both the ACC and RUN positions, but not in the START position.

Disconnect your remote starter from that accessory wire, and I think the factory Ford keyless will work even while the remote starter is running.

THE GOOD: The wipers and radio will now stay off during remote start. Who wants a radio blasting in the driveway in the morning? And plus, if you left the wipers on when parking, and then they froze overnight....well, that would suck.

THE BAD: Many Fords also use this wire to trigger the air-condiotioning compressor. Your AC might not blow cold during remote start anymore.

Yes I used the BLACK/ green wire as the accessory #2. Thats a easy fix for this problem I will have to check later when there is a little more light out. I dont understand what this wire has to do with the keyless entry though. I guess if I had complete wiring diagram Id know. Anyone have a link or down load of a complete wiring diagram of this vehicle? (2002 F150 supercrew with fob entry)

The keyless module will not work if it knows the key is on. The wire that he is telling you not to power is the wire that powers the keyless module. If you do not power that wire, the module does not know the key is on, and the doors will still lock and unlock.
