I was thinking about the viper 3305v or the 3203v. With glass break sensor.

All I need is a good system, trunk pop, no remote start needed.

I can learn to solder, and use a multimeter. How hard is it? CarToys is outrageous. (250+).

Thanks for the help.

This... really depends on the type of vehicle

It's hard to do it quickly. There are soooooo many problems that you can run into. Without a lot of experience, you are screwed. I watch a guy install alarms every day and every alarm never wires up like it's supposed to. There are so many different types of issues you can run into.

this ^ especially when you get into the models with window controls etc...

So I shouldn't try to attempt this? The one I'm looking at is just keyless entry and trunk release. It's all I really need.

2002 Mitsubishi Galant ES. Crutchfield told me there were no harnesses available for my car.

Crutchfield doesn't sell everything. Not saying it does exist, but Crutchfield's word shouldn't be the end-all of that discussion.

Doesn't look terribly difficult for you car as long as panels are easy to remove (never been in a Galant so I don't know). Definitely practice your soldering and make sure you are 100% confident with your abilities before digging in. Do much more research also so you understand what's happening.

It's not the disassembly I'm worried about. Just the wiring, I can take the car apart fine.

Any websites that are helpful?

That car isn't too bad. You will need a relay to pop the trunk though, as its a positive trigger. If you're not familiar with relays and how to wire them, find someone to do the whole thing for you.

Its very EASY to probe a wrong wire and blow an airbag or kill a computer, esp when you don't know exactly what you're doing/looking at. And then theres longevity of install, problems down the line, etc


Id find someone to do it for you, find a local guy on craigslist or something

You don't necessarily need to solder. You can use t-taps if used PROPERLY, this includes stress relief on harnesses so they never get pulled off, and recognizing when a wire is too thick to use a T-Tap (in this case you could cut some of the shielding off but again, experience helps)

You could probably do this car without the trunk or, add a relay later. the door lock wires are in either kick. Let me know if you need a schem if you're going to try it anyways, give me your email and its yours

I'd much rather do it myself than some guy on Craigslist :P

But true, I don't really know what I'm talking about with wires and relays (I do headlight relays but that's).

I don't think solderings that hard, well doesn't look that hard. I just need to get the right wires haha.

Yup, already got the wiring colors. Just gotta learn how to make a relay to pop the trunk and take the plunge haha.

That website has far more than just vehicle wiring diagrams. For example it has a few dozen relay wiring diagrams...

West Palm Beach? I used to live there. Miss it greatly.

This. If you can do head light relays, these are the same thing. Between the12volt.com and bcae1.com (http://bcae1.com/), if you can't figure it out, you need to stay away lol. Do you have a DMM? With a basic understanding on 12V electronics and knowledge of how to use your tools properly you should have no issues. Perhaps I've used them wrong, but I'm not a fan of t-taps. I much prefer solder. T-taps, in my instances, rarely worked out as planned. They either didn't go all the way through the insulation (thin insulation) or cut completely through the wire, which I try to avoid. Perhaps I just had low quality taps that didn't worked as designed, but solder is basically full-proof for me.

You had to have used them wrong or more than likely, used the wrong tool to apply them. I've installed (with no exaggeration) thousands of remote starters and alarms, all with T taps, with a less than 5% come back (if I had to guess) due to a T tap issue.

There's 2 things I leave to the pro's, it's alarm's and tint.

Very possible. I only tried using them twice and with those poor results I moved on to solder and never looked back. If your results have been that good, I'm sure if I had tried them a few more times my results would have improved. I can't say I've installed thousands, or even close to a 100, but of all cars I've done with solder, 0% have come back do to anything wiring related (other than a loose hood pin):)

Eh. While my tint was done professionally because I **** at anything with compound curves. Tinting, or trying to tint probably isn't going to damage a vehicle. May damage a vehicles appearance but won't compromise it's integrity. Worst case is ugly car or lots of lost wasted money. Remote start/alarm...I definitely say leave it to the pros or at least someone with some level of experience (I certainly don't consider myself a pro). My first RS/alarm project turned into a 3 days project and I'm lucky I didn't damage my electrical system. I didn't touch one for about a year after that. Just conversed with other installers and picked their minds and by the time I tried a new one, I was well prepared.

daboy,

Im sure if you were properly taught, you wouldve found that they're fine...working in a busy shop, its unfortunate that speed is looked at equally as important as quality install (they're in biz to make money obviously), and it doesnt get faster than taps. poke and wrap with solder is def the best 0 risk option though, you're right.

I think that is the key word.

Hooking up a car alarm is just about as simple as installing a car stereo...you can get a wiring diagram on this site below....

My god, it's not that freaking difficult. If you can read a wiring diagram and splice wires you can install a **** alarm.

If you don't have confidence in yourself, then you're likely to fail. There's always going to be unforeseen problems but it's in solving those problems that you learn.

I guess I'll follow Nike's slogan, Just Do It.

Thanks man, also, if I happen to trigger the factory alarm, how do I disable it?

Keep the stock key fob handy or you may have to put the key in the ignition to stop it at the moment. Really shouldn't run into the issue though. The alarm unit will have a "factory alarm disarm" wire (light green or light green/black of DEI units if I remember correctly).

mendon99

key in the door and unlock motion will disarm just about ALL fac alarms.

02 Galant, red wire in the drivers door harness (you can get it in the car at the kick, it leads into the door) is the wire you need for disarm

Test it by turning the key in the unlock position on the drivers door

I got the Viper 3303 installed at Cartoys, I now am really, really poar.

Thanks for the help guys. However, I got a question. Any way to make the LED blink slightly slower? It blinks really fast. (On the Antenna/Valet)

daboyfrumdabx

I remember looking through a manual for a way to slow down the LED on a friend's unit. Not the same unit, but is a Viper. I didn't find anything. I did read about a feature it has that once the car is sitting for a certain period of time, it will automatically slow down to preserve power. That's all I've got though. Read through the manual, if your unit has the option, you'll find it in there.
