Saab 9-7x / Trailblazer remote starter

Hi all, Ran into a spot of bother over the weekend attempting to install an Avital 4103 with a 556uw in a 2005 Saab 9-7x. As the install progressed I realized that the high current wires from the Avital remote start 6-pin connector are of a heavier gauge than the wires that are supposed to match up to them from the ignition switch in the center console. Which, to me, doesn't seem to match up right as every other remote install I've done had same gauge wires under the steering console. I looked behind the drivers rear seat at the other harness but found no other wires of a similar gauge. The wires off the center console ignition are around 14awg and the Avital remote start wires are significantly larger. To compound the uncertainty I ordered a 556uw in which the Saab 9-7x key won't actually fit and I believe is the incorrect interface to bypass the specific security in this Saab. There also seems to be some slight variances between 2005-2006 and 2007-2009, my particular Saab 9-7x has GM Passkey 3 where 2007 and later uses SAAB'S TRANSPONDER ANTI-THEFT SYSTEM. Are the wires for remote start really at the center console and are supposed to be that thin of a gauge? What other bypass module should I look into to bypass the Passkey 3 so I can remote start the car without having to lose a key? Also if anyone has any installer photos or reference material they could share it would be much appreciated.

Thank you. I am researching a DBALL2 for this particular application in order to get the remote start to work without having to loose a key. Still seems "not right" to have such a heavy gauge wire going into another that's of a smaller gauge. I'll post a photo to further highlight this and to help others who opt to install a remote start in a Saab 9-7x.

With aftermarket Remote starters they have to use the one size fits all method for design. As older vehicles need the circuits direct powered and newer vehicles are control based for relays.

Funnily enough I picked up a 9-5 HOT over the weekend,haven't really played with it yet but, those wires are only a thin gauge because they feed a relay board up in the dash. If the wires are quite a bit thinner cut and join (I would de-pin the heavy duty plug and re-pin ) thinner cables. And on Euro Fords, I use 18 ga. wires with one 15 amp fuse for all. I was about to add that you'll need a 556U and bury the key when I realised that this is using a GM rather than Euro Saab wiring, i.e. 2nd ACC.

Re pinning is a option for those who have the connectors and open barrel crimp tool or are good with needle nose pliers to crimp them. Soldering is also a option if you have the connectors. Most DIYers wont have the colored wire or terminals. So you can thin out the heavy gauge wire to be a closer match to the wiring you are connecting too. Then tape and zip strip(tie) them to the bundle of wires you have connected to securely.

Could I suggest soldering mandatory once everything checks out OK?

Yes best for armatures (newbie's) to solder all connections. I only solder security connections, under hood(Engine compartment), and any other connection that are resistance based along with resistor and diode connections. All other connections are through hole twice and tightly wrapped down wire then added wire is folded flat to connected wire and tapped down wire and back up then zip stripped (tied). Have a Viper 550HF installed since 1994 in one of my cars still going with out issue and have never had a comeback due to wiring. Also no cheap tape 3M (Scotch Brand) Tartan 1710 or Super33+ for exposed connections only!

Hey all, After reading what Lurch228 stated, it makes sense that the remote start industry is a "one size fits all" and that my particular application has smaller gauge wires but that's ok. Just threw me for a loop as I've not encountered that before. I did have a 556U but the Saab 9-7x key would not fit inside it and the more I dug into the electrical system and it's onboard security/data, it appears that I needed to get the DBALL2 interface in order to get the remote start and key to work without having to loose a key. We'll see how that goes this upcoming weekend on the install. This is the harness from the center console below. I was in a bit of a rush to get something to work last weekend and all had was red wire to extend the harness. Howie II's suggestion about de-pinning re-pinning is a viable option and one that I am inclined to go after. I also will solder and heat shrink my connections, I have a Weller bench digital soldering iron as well I picked up after I learned my lesson about t-taps and other mistakes a young guy can make along the way. And as luck would have it I do have Super 33+

Thought I replied but I was stuck in a hospital A&E with poor WiFi and signal. As I noted before your ignition system is US GM, doesn't have nearly the same "quantity" of immobiliser "gizmos" the Euro cars have so run with the DB-ALL2 it should be fine.
