1998 jeep grand cherokee laredo door lock

Ok here goes.... First off I'm no rookie when it comes to remote start, alarm, security, sound systems... I was an installer for  years at a professional shop. And I have read and read on this topic before and I'm still unable to figure this out... With that out of the way, here goes...

I recently purchased an Aftermarket Generation AGA-1201 Remote Start, Keyless Entry, Alarm system.. ( http://aftermarketgeneration.com/catalog/product_info.php?cPath=23_80&products_id=32)

All of the wiring seems fairly easy on this unit. Pretty straight forward. The problem I'm running into is the door locks. I've read all over this forum that the door luck and unlock work on a negative pulse. I pulled the door panel and found the ORANGE / Purple wire at the door lock harness, I probed the wire to check the polarity. At rest, I have a negative reading. When I press the door lock button, I get a positive reading. Same thing goes for the door unluck on the Pink/Black wire.

So my question is this, are my doors somehow reversed from everything I've read on here?? My alarm has the option to have either Negative or Positive output for the door locks. I just don't want to hook up the wrong polarity and mess my alarm system up. To prove that my alarm has the option for either output I've included part of the install manual concerning the locks:

Pin3: Violet: Unlock #87a Normally Closed

Pin 4: Blue/Black: Unlock #30 Common (Output)

Pin 5: Brown Black: Unlock #87 Normally Open (Input)

Pin 6: Violet Black: Lock #87a Normally Closed

Pin 7: GREEN/ Black: Lock #30 Common (Output)

Pin 8: WHITE/ Black: Lock#87 Normally Open (Input)

Pin 9: Red: Constant +12 volt input

Pin 10: Black: Ground

So it appears that whichever the locks use, positive or negative) should be connected to Pin 5 and Pin 8. Then Pin 4 and Pin 7 are connected to the door lock/unlock wires at the harness.

I know this is a lot of info but I really need someones help.

Thanks,

Mike

PS... The wires at the kick panel are not the same as the wires inside the door. Does anyone know what color they change to once they enter the cab of the vehicle??

I just wanted to take a second and thank everyone on here for their help. I got the DEI 455T in today and it was so easy to finish my installation. It was so simple.... Just two wires! I would recommend this site to anyone that's having any dificulties installing anything. You guys are the best.....

Forgot to to hook up the door trigger and this alarm keeps re-arming itself after 35 seconds of being disarmed, even with the door opened... I'm hoping it's because of the door trigger. Crossing my fingers cause that's alot of wires to pull out! LOL.

Again, thank you all!
