simple diode and alarm question

Here's a simple one that I just want to make sure of before I do the install. My friend already has a basic alarm in his car. We added a bulldog rs82 remote starter (very basic). I have to install the hoodpin switch to the remote starter, but I also want to piggyback it onto one of the alarm's wires so the hood is also a "sector", so to speak. Previously, the alarm didn't cover the hood. Basically, I want to know, if I install the hoodpin to the remote start, and then piggyback it to the alarm, which way should I face the diode?

Hi cpgoose, connect the cathode sides (stripe) of two diodes towards the hood pin. Connect the anode side of one to the remote start and the anode side of the other to the alarm. the12volt • Support the12volt.com

You really don't even need to use diodes. There won't be any feedback issues. But what was posted above would be correct.

hey, thanks for the replies! I didn't realize that I would need two...but ok :-) Can I just confirm what this is doing? The two diodes are preventing feedback from the hoodpin to the alarm and the remote starter? Here's a picture to make sure I got what you're saying: http://www.angelfire.com/nj4/cpgoose/hoodpin.htmlQ: What's the best nation in the world?

Thanks 12volt! I got it to work! I put that 3rd diode on the door trigger wire like you said, but then I made the mistake of putting the wire coming from the hoodpin switch before the diode (in other words, the door side rather than the alarm side of the diode), and the domelight was still coming on when I opened the hood. So then I switched it, and put the wire on the alarm side of the diode, and then it worked. One of these days I'll understand what it's doing Thanks for the help!Q: What's the best nation in the world?
