Hi, i work in home construction and remodeling and have lots of electrical experience. However, I have never done any wiring on a car before. I am going to attempt to set up a remote starter for my car but i just have some confusion about the "control module." I am going to tell u what i am planning to do and please tell me if i'm wrong. I know there is a positive 12 volt wire coming from the battery to the ignition switch. I want to cut this at some place under the dash and attach it to my control module right? But obviously since I cut a wire, it splits it into 2 wires. I wanna connect the battery side with the positive 12 volts to the control module, but what about the other side that connects to the ignition switch? This same question goes for all the wires pretty much. For example, I find the starter, ignition, accessory, brake, and trunk wires, then I am supposed to just split them and connect one of the 2 wires from the split to the control module? or both? i hope u can understand my question basically i have a wire from the control module and 2 wires (from the split), thats 3 wires total from each starter, ignition, etc connection, and don't understand which to connect. Will wires become inactive or pointless basically?

Ok.....year/make/model would help...and what kind of system. I know you want general info, but all of this info helps us greatly. In most cases, there is no reason to "cut" any wire in the vehicle, except the starter wire if you are during a security system, or antigrind relay.

Ok sorry. The car is a 1994 mercury sable 3.0L v6. I have found the wiring diagrams on this website. Maybe I can rephrase my question better. Should I just splice into all the appropriate wires and therefore keep everything hooked up the way it is? Only changing that my control module is attached to these circuits? Therefore, the conrol module sends electric signal to the splice to, for example, the trunk release wiring? In this situation the electric signal the control module is sending goes to the splice to the trunk release but also to whatever controlled the trunk release before I fooled around with it such as the OLD remote trunk release system that came with the car. Seems like you are therefore connecting two hot wires together, two different systems that send electric signals to the trunk release.

also i am thinking about getting the omega excalibur mars-22 system. it seems like a quality company for a good price and it doesnt have an alarm system which i dont want.

The first rule is solder, don't splice, the second rule is that there is no general rule for R/S, every make and model is different with yearly variations, the third rule is test everything, the fourth rule and no insult intended but generally household/construction electricians make really lousey auto electricians because of AC, lower currents and pre-conceived ideas!

Ok well my question is still waiting to be answered. Yes i used the word splice because thats what I meant, the word splice means to join together (soldering is a way to do this). Now if someone could answer my question and not criticize my wording or knowledge that would be great. Also I don't care whether you would think I would make a good auto electrician or not, i am just trying to set up this remote starter thats it. Let me put my question in other words again. When you have a NEW remote start/keyless entry control module WITH POWER, and the OLD factory module (remote for my car has lock, unlock, trunk open, and panic functions) WITH POWER, and you join these wires together, aren't you just connecting two hot wires together?

No
AC and DC are totally different. You will not need to cut 1 wire in the car. Everything will be "spliced" together. The only wire you could possibly cut would be the start wire IF you are installing a starter kill or anti-grind. Mars/Omega/Excalibar is rather cheap product. You won't find many reputable shops that install them. I would look for something else. DEI (Viper, Python, Clifford, Valet and others), or Compustar. Others here like Audiovox/Prestige as well.
Now that I think about it, those doorlocks may be 5-wire reverse polarity. I'm too lazy right now to look up the tech sheet for it though. If they are, you will need to cut the lock and unlock wires and use relays.

unlike household 110v wiring, wires dont need to be cut and twisted, you can open up the insulation and do a military splice(just as strong and reliable as solder, actually more reliable if your not good at soldering ) after stripping open insulation, use a pick or a small flathead and poke open the copper to create a "hole" thead your new wiring into the hole and twist around going both in front of your added wire and behind , you can crimp with pliers for added security feeling of your wrap them wrap with a good quality electrical tape,only wires that may need to be cut and butt connected or soldered is starter wire(if system has antigrind circuit) and possibly door lock wires if your car doesnt have factory keyless( if it does they are tap in also)DO NOT USE household wire nuts on any of your connections

Hot wire = pre-conceived ideas! I rest my case! Sorry I had to do it. Never known an OEM alarm to be compatible with an aftermarket alarm, too many different ideas. about what does what, data etc.

Hey JWorm and Jim Hunter that helps out so much. I really really appreciate it. jim hunter wrote:

Just out of curiosity, why are you so serious about not using wire nuts? I was gonna solder everything and just tape it but I am still curious as to why wire nuts aren't a possible alternative?

[/QUOTE] I just liked Omega because its been around since 1971 made in the USA but if u say it isn't good quality i'd like to get something else. where is the best place online to shop for a DEI or something quality around 50-60 dollars with just remote start and keyless entry (no alarm) with a remote that has all the buttons on it? by that i mean i dont want 2 seperate remotes, one for starting the car and one for unlocking the doors or popping the trunk, i want a system that comes with a remote that does everything. thanks

We carried a few Omega systems for a couple of months, we just sold our last mars 33, and that is it! Just horrible....I can get more specific if you want, but I'm not gonna start a rant. I love Compustar stuff (have one on my own vehicle). Audiovox product is rock solid....just had a customer come in today with an Audiovox system that she had installed 9 years ago, and it is still working strong. I also like the Autopage stuff. DEI product is also good. Just check any of these manufacturers sites. Find the model you want, and Google it. Have fun trying to find something in that price range, that is willing to back the product up. I'm not trying to sound like a jerk.... I see so many people buy their own equipment off the internet, and decide they are in over their head. They bring me their junk, and want me to install it. In the end, Most likely, it ends up costing them more to have their own stuff installed, then it would of been to buy and have something installed by me. Don't get me wrong, we will help all we can, and I hope you understand some of the comments made earlier. Just because I know 12 volt, doesn't mean you would trust me to come wire your house. Two completely different animals. Good luck on your search.

DEI tries to prevent online companies from selling their products so you will often see their items removed from ebay or other sites for copyright violations. I just took a look on ebay now and saw a Valet 561r selling for about $49 plus about $10 for shipping. It is a basic model by DEI, comes with only 1 remote that will do locks and start your car. I prefer Compustar. Look for a RF-1WG2-AM. It is there basic model. Should be able to find one for under $100.
