Guys,
I have a pretty good understanding of electronics and automobiles and was wondering if it is worth the aggravation to try and do an install on a car alarm these days? I know the answer to that question pretty much relies on the ability of the person asking, but I dread the idea of paying a 20yr old kid at Best Buy $200 to do something half assed on my vehicle.
I've gathered the tech sheets for my 2008 Dodge Ram 1500 Quad Cab from here and also have a factory Dodge Manual. I also understand that I will need a interface (XK03, DBALL?) to install as well. If I understand this correctly and looking at the instructions for the DK03, it appears that the unit simplifies the install quite a bit. Am I correct in saying that?
Also, looking at the tech sheet for the Dodge Ram for instance on the Second Starter, it shows the Polarity to be -180ohms. Is it as simple as soldering a 180ohm resistor inline between connections to get the correct polarity?
What are your guys professional opinion about this? Like I said.. hate to take it to a shop and they call me back in two hours to say it's finished. If that's the case.. I know I could do it in about 6-8 hours and have all the connections soldered and ran properly. Hell.. I don't care if it takes me two days. I would rather do it myself and gain the knowledge.
Thanks.

You could look at a video of a bench setup I did a few days ago and see if it is something you would like to tackle.

EXACTLY what I was looking for. I will check it out later on and see what questions are left if you don't mind. Thanks and Happy New Year!!

Depends on your confidence level and ability.
For example: I just installed a less common A/AS in my 98 GMC. All it has is passlock to deal with. A 2008 dodge has a bit more.
Before I go further, let me give a bit of perspective on my experience: I'm not exactly a beginner. Been in the automotive and aerospace industries for about 30+ years. I have done alarm installs before, but not as a sole job.
I am a little older (49) and broken up from my occupation so I can only stand being crunched up in the foot wells upside-down for so much time.
It took me a couple days of easy working at it to get it all done to where I want it.
I am like you though: I can't stand the thought of some 18 YO Scotch-locking and vinyl taping my vehicle wiring. I prefer to do these things myself so they are done properly (IE: solder, heat shrink, etc), even if it sucks up a couple of my days.
It is a lot of frigging around and you are ultimately the one who will have to decide if you're good (or capable) enough, but I'd say give it a go if you can do without your vehicle for a couple days (if it doesn't go as planned) and have the ability to program any bypass modules you may require.
Have a Digital Multimeter at the ready too.....:)

I appreciate it. I still have a couple years at the young age of 39 crunched underneath dashboards before I make my kids do this crap! lol...
I have still been doing some research and watched this video above, but really didn't answer my questions. I get the whole solder the appropriate resistors in line based on the tech sheets, but I was also wondering about these bypass modules. If you take a look at the instructions found here, it appears to simplify the install. Is that the case? I guess my question is, what is the sole purpose of that unit?
I've been soldering points on motherboards that are smaller than frog hairs since I was 18. I have the Dodge Manual and the tech sheets from this forum. I am pretty confident I have the "ability" to do the job.. I just want to make sure that I have all the research or proper approach to this before I dive into it. As far as tools go... believe me there is no issue there! ;)

Keep in mind I'm no "pro" installer, but when I looked in to it on my 2004 300m the "xpress kit" was required to bypass the OEM security system.
Likely similar to the resistor "trick" I did with my older gm, but probably a bit more involved design.
Someone with more experience will have to chime in on that one...

Your expectation that a professional installer will "Scotchlock and vinyl tape" your vehicle up is a little misguided. Remember YOU are the customer - if you are against scotchlocks (and you should be) this should be brought up BEFORE paying the shop. If you want the connections made a certain way discuss your desires with the shop and don't agree to allow them to do the work unless they are willing to do what YOU want to YOUR vehicle. Finally, as the customer, you have the right to inspect the installation BEFORE the vehicle is put back together. I was a professional installer (yes, when I was 20 or so) for several years while I was in college and I NEVER had a customer ask to inspect my work - that always surprised me. Also, as being a former 20 year old installer I can tell you there are some amazing 20 year old installers out there but there are also some out there that you don't want touching your vehicle.
At the end of the day, it depends on your personal preference. If you can use a volt meter and make solid connections then you should be able to complete the installation. The final question is it worth it to you? If you pay a shop there are benefits - they are insured for damage and will offer you a lifetime warranty on the installation. If you damage your vehicle during the installation you'll kick yourself for not taking it to a shop as you pay out of pocket to repair. If you finish the installation and it works for the first year or two but then has problems it is YOUR installation and most likely no shop will have any interest in working on it. One other thing to consider is do you want to do it (ie do you think it would be fun)? If you don't think this type of work is fun then I would take it to a shop you trust.

Not at all. That's what you get at some places because that's what they know or what gets it done the fastest. I wouldn't call them "professionals" either. They're the "Best Buy" places most people seem to end up at. I would assume primarily for cost reasons.
Personally, I wouldn't go to such places.
Not knocking young guys, some are good.
Some not-so-much....same with some "old guys"....

You missed my point. As a paying customer you have the ability to set the parameters of the installation. It may cost you a bit more, but if you don't want scotchlocks used they should not use them.
If you go in and drop the vehicle off and don't say a single word about how you want it done you leave it up to the installer to decide if scotchlocks are acceptable.

No sir, I didn't.
Hence the " I wouldn't go to such places".
If I have to specify such things like "no scotchlocks" then they are not doing the type of quality work I want done anyways.
I would simply take my business elsewhere.
