2003 Nissan Altima Remote Start info

Hello Everyone, first post here. I am attempting a 1st install of a remote start system on my 2003 Nissan Altima ginuea pig with an Avital 4103 w/ a Dball2 bypass module. I have installed quite a few car stereos, but nothing this "integrated". I have some questions before I get started, if y'all can help. Thanks in advance. As far as wiring the Avital 4103 goes, i have the following wiring scheme as follows. Can someone please help me see if I have this right?

Thanks for the guidance Kreg357, I have a couple more questions if you can. 1. Do both of the RED, 30a high current inputs go to same Green battery positive wire in ignition harness? 2. on the 4-pin satellite, the orange to spdt 30A relay pin 85, what is that for? 3. on the Relay wiring you indicate the orange accessory out from the satellite harness to pin 85 on relay, then also Relay Pin 85 to 4103 PURPLE (-) STARTER OUTPUT (on satellite harness also I believe). This would mean there are 2 wires connected to pin 85- the 4103 purple starter out and the orange accessory out. I'm a little confused. Thanks for your patience.

Sorry for the mistake. The extra relay is for the vehicles Starter2 circuit. The relay Pin85 connection should be to Pin 3 PURPLE(-) STARTER OUTPUT only, not Accessory. So only one wire to Pin 85. 3AM is probably too early for me to be typing... Soldering is fun!

No worries, your input is much appreciated. So on the Heavy harness, do both of the RED (30A) HIGH CURRENT 12 INPUT connect to the SAME green 12v Battery? That won't work unless that Green wire is capable of 60A or more powering 2x 30A plus accessories? I have yet to open up under there and see what i'm working with. I'll find out next weekend for sure! Can't wait to tackle this. Thanks again for the help, it is much appreciated.

If that Green +12V wire at the ignition switch harness is the only wire supplying power to all the ignition circuits, it will handle the load OK. The only extra load on it will be the (+) Parking Lights out of the 4103.Soldering is fun!

Hello again, the saga continues. I'm trying to figure out how to wire up the DBALL2 bypass module. I have the rest hooked up, but need to make sure I do the bypass correctly. It seems like almost all wires are going to the ignition wire but I can't be sure. What is the dashed line mean between ignition on key side & vehicle side? This is a black dashed line compared to the blue dashed line which indicates that the connection isn't necessary if going to use D2D wiring. 14 pin connector:     #8- hooks up with #9 on 10pin connector to ignition on immob. harness     #9- hooks up with #6 on 12pin connector to ignition on immob. harness 10 pin connector:     #9- hooks up with #8 on 14pin connector to ignition on immob. harness      12 pin connector:     #6- hooks up with #9 on 14pin connector to ignition on immob. harness     #11- to data pin on immobilizer harness

If you are going D2D, the dashed Blue lines are made via the DBI D2D harness. The dashed Black line is actually a cut wire. You must cut that Red Ignition wire at the immobilizer module connector. Internally, the DB-ALL2 will make that connection under normal conditions and open that connection during a remoter start. You can combine the 14 Pin Blue Plug, Pin 8 Yellow wire with the 10 Pin Black Plug Pin 9 Pink wire at the DB-ALL2 and just run one wire to the steering column. Same for the DB-ALL2 Orange / YELLOW and Gray wires.Soldering is fun!

Well this attempt was unsuccessful. I found that the red accessory wire was actually another ignition wire. It appears that the wiring guide for my vehicle was wrong. i reconnected the ign/access program to ignition instead of accessory, and that should've fixed it but it didn't work. The remote start would control the locks, trunk, and the remote start would initiate, but the starter wouldn't engage. any ideas?
