If anyone would be so kind as to answer these questions for me, it would be greatly appreciated. In the posts above, it states that each door trigger needs to be diode isolated if the vehicle is equipped with factory keyless entry. I understand what a diode is and that I would need one for each door, but which direction does it go? What, exactly, does diode isolating each door do for me functionality-wise? Would it be easier to wire them differently somehow with a different configuration to give a different functionality? I'm asking because, as it currently stands, I press the OEM KE remote button once to unlock the driver door and a second time to unlock all doors. Is the purpose of diode isolating the door triggers to maintain this functionality? I would prefer that all doors unlock at the single press of a button on the alarm remote that I want to install. Would eliminating the diodes do this for me? Am I missing the boat on this and the diodes have something to do with triggering the alarm and nothing to do with KE functionality?

I have all of the components I need to install my Autopage RS-850LCD, but this diode isolating business is the only thing that's keeping me from attempting the install. I think I have a good enough handle on the rest of it. Again, any help with this would be greatly appreciated. If anyone in the DFW area would like to drive to Keller and watch over my shoulder to make sure it's done right, there would be food and any beverage of your choice available to you. ;) I really want to do this myself, I just need some guidance particularly in the diode area.

I have many questions about the input and output harnesses on the alarm and would appreciate any help I can get with these questions. This is an Autopage RS-850LCD alarm and I bought a DEI 556U for the PATS bypass for a 2004 Ford F-150. I think the only output function I'll be using is the Remote Start, no other functions such as window rollup or anything. If I'm wrong in my thinking about outputs, let me know. I am a complete noob at alarm installs. I have found all of the wires in the truck to make connections to except for the door triggers, which I was planning to substitute with the dome light. Will that work?

INPUT connections:

1. WHITE/ Black (-) neg safety shut down input for hood pin switch

I'm not planning to use the hood pin switch for the alarm or for remote start safety reasons, anything special I should do with this or just not connect to anything?

2. WHITE/ Violet (+) pos safety shut down input for brake switch

Connect this to brake wire

3. BLACK/ White (-) neutral safety switch input & (-) Remote start toggle switch input

Do not connect this one either?

4. Blue Zone 2/Instant trigger ground

Ground this

5. WHITE/ Green (-) Diesel wait-to-start

Will not use

6. Green Zone 3/Negative door pin trigger input

Not used?

7. Violet Zone 3/Positive door pin trigger input

Connect to dome light wire? (Dome wire is +)

8. WHITE/ Blue (-) instant start and turn off input

9. WHITE/ Red Tach

Connect to tach wire

OUTPUT connections:

1. Yellow (-) Ignition 3 control output

Not used (?)

2. BLACK/ Violet (-)200mA Channel 6 programmable output

3. BROWN / White (-)200mA programmable output

1. Horn Output (Factory Default Setting) or

2. Factory security rearm signal output

For horn output, a relay would be needed?

4. White (-)200mA Dome light control output

I believe this is just for interior illumination, don't need?

5. BLACK/ Red (-)200mA Channel 5 programmable output

6. BLACK/ Green (-)200mA programmable output

1. Channel 4 programmable output (factory default setting) or

2. Key sensor bypass output

7. Gray (-)200mA Channel 3 (trunk) output

not used

8. Pink (-)200mA programmable output

1. 2 steps door unlock output (factory default setting) or

2. Factory Security disarm signal output or

3. start status (shock sensor bypass control) output

9. ORANGE / White (-)200mA grounded output when disarmed

10. Orange (-)200mA grounded output when armed

Ground both?

I may have door lock/unlock questions later, but these are the ones that are really blowing my mind. I can put scans of the instructions and/or diagrams up later if needed (I would have done it for this post, but I don't currently have easy access to a scanner). I wouldn't be opposed to someone in the DFW area helping me out by looking over my shoulder while I install. I could make it worth your time if someone wants to do that.

Could someone PLEASE help me out with this?

Ok, I think I have all of that so far. My 556U documentation says only 3 or 4 of the 6 wires coming off of the wire harness will be used: black - chassis ground, red - +12V constant, and blue - status output from remote start. The Violet (+) keysense wire from the 556U may POSSIBLY be needed. Does that sound right? I'd just connect the blue wire to the Yellow (-) Ignition 3 control output as stated in mo12v's reply to my original post. Since the keysense wire is pointed out in the wiring info for the truck, can I assume that I will need to connect the keysense wire from the 556U, or should I try without first?

Now to the door locks. It looks as if the truck has a negative trigger door lock system (correct me if I'm wrong). All I have to do is connect the unlock and lock wires from the alarm to the unlock and lock wires from the truck and that will activate the relays in the truck, not requiring extra relays. Is that right?

It looks like I'm close to having all the info I need to complete this. mo12v, thanks a ton for the info you've already given me.

3. BLACK/ White (-) neutral safety switch input & (-) Remote start toggle switch input

Do not connect this one either? *Tape up

If you just tape up this wire, remote start will never be enabled

you really should hook this wire up to a ground toggle switch, the mechanical working on your vehicle re-connecting your battery will appreciate it a lot better than the vehicle starting itself magically while he is under the hood. if not then you need to ground this wire

in the last ten or so days I have installed the autopage 750 remote start into a 2002 nissan frontier, and the 855 in a 95 chevy pickup

If I wire up the hood pin switch, can I ground the input #3 wire and net the same effect?

Whhooops..........Charles_R_H is right.......Guess I'm going blind from this posting stuff

U could use a toggle switch on #3 ..

I still would put Hood PIN switch on #1 Law suits R bad

got power windows??

you should install the auto page window module as well, priddy easy to install

gives you 1 touch up and down from your driver's side switches as well as venting from transmitter, roll up when armed, and other functions

i ran into a few bugs with it, but put in a diode here and there and it works great
