2010 mercury mariner, avital 5303

Will the GREEN/ purple negative trigger take care of all the doors? I've seen different wiring diagrams that list an all trigger and separate pins for all doors for different year escapes. Nothing pertaining to 2010 or a mariner. Thanks for the help

It might, the only way to know is to test it. Hook up the one wire and open each door while it's armed. If you have a light on the dash that tells you which of the 4 doors are open, you will need to diode isolate all 4 doors and tie the diodes to the door trigger input. No question is stupid or not worth asking. You were once a noob, right? :)

The avital 5303 has a 2nd status output that can be programmed to turn on rear defogger under 55 degrees. I would also like to attach the heated seats to this output also. Would a relay be needed? If so can someone help me with wiring.

The status output only puts out 500mA... A relay would be wise. :) Can't go wrong with a relay!No question is stupid or not worth asking. You were once a noob, right? :)

How would the relay be wired?

I don't have any data on the heated seats or defroster, so I'm not sure whether you'll need a (-) or (+) pulse/latch output. The basic setups of relays are located here: https://www.the12volt.com/relays/relaydiagrams.asp The heated seats and defroster will need to be metered to find the right wire and setup I'm sure.No question is stupid or not worth asking.

The seats and rear defrost are both negative latched. Will this work for the relay? 30-ground 86-negative output from Alarm 87-negative output to rear defrost and heated seats 85-12v input

Yeah, that looks good to me, as long as they're negative latched. It's good practice to always put your ground leg on pin 85, so switch 85 and 86. It's also good practice to put the load (output) on pin 30 and use 87/87a as the source. Your diagram isn't wrong and would work though! Here's what I would suggest: 30-negative output to rear defrost and heated seats 86-12v input 87-ground 85-negative output from Alarm It just makes it easier for people to troubleshoot.No question is stupid or not worth asking.

Can anyone tell me what wire colors to test for the door pins? Also are they only accessible at the kicks or can they be reached at the sjb?

Here is some info from Audiovox : All Door Trigger GRAY/VIOLET (-) IN HARNESS IN DRIVER KICKPANEL LF Latch GREEN/ VIOLET (OPEN) SMART JUNCTION BOX    RF Latch WHITE (OPEN) SMART JUNCTION BOX    LR Latch GREEN (OPEN) SMART JUNCTION BOX    RR Latch YELLOW (OPEN) SMART JUNCTION BOX Test for the GREEN/ Violet "All Door" trigger as a standard N.O. (-) type trigger signal. The actual door trigger's listed are N.C. and would need a DTIMazda module or the DEI TechTip #1921 to be used by the after-market alarm system.Soldering is fun!
