which way to face the diode?

hi.....long story short.....i installed a remote starter into an existing alarm. Maybe 2 out of 5 starts, the alarm goes off, and the led indicates an door or the trunk was opened (even though they weren't).  Now, I think the door wire was piggybacked onto the trunk's wire on the alarm. I think this because:  the wire for the door that goes into the alarm is missing (it's not even in the plastic harness that plugs into the alarm).  Plus, when you open a door or open the trunk to set off the alarm, the led blinks the same number of times (even though it's not supposed to).  I think they tied the door wire into the trunk wire.  ANYway....the guy from the alarm company said to install a diode on that trunk wire going into the alarm, and maybe that will prevent some of the feedback that I might be getting, but he wasn't sure which way to face it.

 Which way should the stripe go.....towards the alarm, or away?  I'm thinking away?

Thank you.

(+) trigger = Cathode band towards the alarm

(-) trigger = Cathode band towards the trigger

Thanks guys!  When you install the diode inline with the wire:

• 1.  Do you have to cut the wire in half?.....or just strip two separate parts of the wire and install it that way.  Please see picture below. 
• 2.  If you install it the second method, can you thread the diode through the wire, and wrap the diode around it?  Will that prevent the flow?

Crap....does #1 work at all?  I was given wrong information before, and I did it this way (for a different application).  I threaded the diode through the wire, and wrapped it around. 

By the way, I mis-typed in my post.....I meant threading the diode for the first method, not the second.

ugh....I hate soldering, especially in the car

Yea, that makes sense.  Like I said, I guess I did it wrong because I used the first method for using the starter kill and the window module on the orange wire of the alarm. I haven't had any bad effects, though.  Are there some negative effects that I should be looking for?

Thanks for the help Jeff!
