2000 Grand Am, Remote Start

I have a few questions on using a relay on an aftermarket remote starter with my 2000 Grand AM.  My remote start module provides a ground signal on a wire when it is both armed and in remote start mode.  This signal in turn activates a passlock bypass module for gm vehicles.  When this module is activated the ecm believes the key is in the cylinder and also that the key is in the accessory position.  This causes the battery on my car to run down over a period of about 24 hours when it is armed.  To prevent the passlock bypass module from activating while the alarm is armed I am planning to use a relay hooked up like this:

Ground output from remote starter - Pin 30

Ground sensor from bypass module - Pin 87

Ground To Frame - Pin 85

one of three 12V positive when in remote start mode wires - Pin 86

I have three wires to choose from.  Ignition 1 and 2 and my accessory wire.  My questions are what amperage relay should I use, what wire would be the best to pick, and if I were to hook it up to the accessory wire would a relay hooked up like this on the accessory circuit take enough power from the wire to disturb the components running off of it.  Also the entire time my car will be running the relay will be energized unless I use a blocking diode.  Where would I be able to find a blocking diode I could use on the accessory circuit, if i have to use several in parallel would anyone have any recommendations of what to use. 

Thanks,

What bypass module and remote starter are you using ? I would try to remedy the problem instead of trying to bandage it up as the relay will only be a temporary fix. Post the way that you installed the bypassmodule and to what colors and we'll see if we can fix the problem with the module draining your battery.

As far as the question at hand , use a 30/40 amp relay and you'll be fine. The diodes ( 4006 series )you can get up to a 6 amp in most Radio Shack or electronic stores.

I just re-read your post and just wanted to make sure that you are using the GROUND OUT WHEN RUNNING wire to activate the bypass module ? Does the remote starter have this type of wire ? If so, then it should not be emitting a negative pulse when you are the system . You may have the wrong wire if your module is always on when armed and when remote started.

The remote start module only has a wire to provide ground out when armed and when running.  As to your question about that alarm system and bypass module, I have a delta alarm system - model pro2000 and I am using a passlock bypass module called the IPPME.  The alarm diagram doesn't show any wire that only provides ground only when running although I wish it did.  That is why I was considering using a relay.  Currently I have the ground out from remote starter hooked up to the brown wire on the Ippme but I believe the problem is that the wire provides groundout also during armed phase.

Thanks,

Is this the Delta Pro 2000 FM  alarm system ?

With the IMPPE module, try to hook up the RED ( thicker gauge wire ) to the primary ignition source instead of a contant source. This way, the module will only work when the ignition wire is activated at time of remote start regardless of the fact that the armed/ground out when running wire is always outputting a ( - ) signal. Try this out first and see if this will infact work . If it doesn't remote start the car, then you know you will need it to be a constant power.

I will see if this works, thanks a lot for your help with everything.  You guys are really great.  If it doesn't work I will be sure to write back on here.

Thanks

By the way yes, it is the Delta 2000 Pro Fm Alarm System

I can't connect the IPPME to a temporary power source.  The unit keeps the code for my car in its memory and when power is disconnected for any length of time the memory must be reset by turning the key on for ten seconds. Sorry

Here's what you will have to do ( I had to do this to a 1995 Monte Carlo that did not have a GROUND OUT WHEN RUNNING WIRE ):

You will have to make a ground out when running wire with a relay that will ONLY activate when the ignition is energized:

• 86 + 87 ---> GROUND
• 85 ----> Ignition 1 from vehicle ( PINK on car )
• 30 ----> This is now your ground out when running wire. This will emit a ( - ) signal as long as there is power to the ignition wire.

Try this and post your results. Unfortunately, the company did not think of this when they made the GROUND WHEN ARMED wire to be constant !
