Installing Security System

abiman · January 15, 2011

Hi,

Does anyone has experience in installing Viper 5901 RemortStarter/Security system on 1997 toyota Sprinter CE110 or other car?

I need to find wires in my car and need help.

Also is there any place I can get this done?

thanks

Well I've installed a few and could offer you some tips, but let me ask this from you first. How good are you with electrical systems in cars? Installing systems with remote starters are a serious PIA and unless you are familiar with the electrical system of your car, it would be a lot safer to get it professionally installed.

HI,

I'm not much familiar with auto electrical systems. However I'm electronics engineer and have good knowledge/experience in electronics/electrical systems. Also I have proper tools. (I'm mostly in to embedded control systems ,robotics and AI)

I tried to install this my self. however found that it is real PIA to find wires from car as you said.

Specially I need information on ignition harness and how it operates.

Ok so I guess wiring should not be a problem to you. Exactly which wires on the harness you got with the viper unit do you have trouble with?

HI,

Basically I need information on all the wires in remote start heavy gauge connector of viper 5901

But first, what does ignition1 and ignition2 mean? How to find that wires with multimeter? does this relevant to diesel AT car?

Basically those two wires are the ones that stay around 12v during cranking. It's a secondary power source for the module.

Ground the black probe of the multimeter and use the red one to check the reading on the wire. Basically unless someone can tell you the exact color of your wires you will need to check the readings of the wires connected to the ignition one by one while cranking. Either way if you have the right wire it would be one that stays around 12v during cranking.

About the second ignition wire; it basically does the same job as the main AFAIK. I can't remember too much on it but I believe you can use the same wire as the ignition wire you tapped into first.

As for what would be relevant to diesels, I haven't installed any on diesel vehicles but I believe the only difference is that you will have to run the glow plug wire to the unit.

Also this should give you a better understanding of what the wires are:

hi,

Ok I have done some work and found wire connector. It has One BIG white wire which I assumed +12V. When I pull this connector out car wont start and no lights on meter panel comes on. So I assumed this connector has start wire. Then I pulled only Big Black/RED wire out from connector and fixed connector in place. Now car wont start(Starter motor does not engage and indicator light for heater coils (this is diesel CE110 car) doesn't work.) But other lights in panel work as normal. SO I assumed this should be starter wire. But when I measured voltages it always reads +12V regardless of the position of key. Then I pulled connector out and measured voltages on each wire and found Black/RED, Big White and medium white wires has +12V. So what is this connector? Am I looking in wrong place? I have attached few pictures of connector I'm talking about.

Why are you going through all that trouble to find the ignition wires? All you need to do is find it it from the ignition cylinder on the steering wheel, and follow it down to the connector, you can even tap into it at basically any point you wish.

hi ok thanks for suggestion and i found them under steering wheel. I will update as i continue

thanks for support

JDnet, from a point of view of making as difficult as possible for a potential thief to disarm a security system, where do you think it's best to intercept the necessary wires ?

Also as a general point, I understand the value and convenience of things like keyless entry, and a remote engine and AC start in a country like ours, but how prevalent is automotive theft in Sri Lanka? I'm asking out of curiosity.....

Well the idea place to tap into the harness would be at the connector but eitherway do you think a car thief will take out the remove the screws, take out the dash panel and try to figure out which wire to cut, all while the alarm is set off?

Automotive theft used to be a little big but it seems to have died down in recent years. Mainly due to the fact that they can't send stolen cars up north anymore. I'm not saying it doesn't exist though.

One things like remote start, here's my 2 cents; Running a car at idle for 10 mins or so to cool it off is an utter waste of gas. The best thing to do is get into the car with the windows rolled down and start driving and once the hot air is out just switch the a/c on?

Cool, I'm glad I could help. I must warn you that although working on automotive electrical systems is time consuming and annoying, it does get addictive.

I thought to add remote start to car to start it while I'm going to it, So i don't need to wait little after starting car. (Some one told me to start car and wait 1min or so before driving to let oil get in to relevant parts of engine properly specially in diesel. Is this true?)

Besides I think it is cool feature to add

lol I wasn't saying it's not cool to have. It's always nice to have all the bells and whistles.

As for the oil thing. If the car has been sitting for a while (i.e. the morning), 10 seconds is plenty to get the oil upto the vital parts of the engine. The best thing you could do for your car is take the first few kilomteres nice and steady without any sudden accelerations. The only thing you would need to do different in a diesel is to let he glow plugs warm up until you start the car.

The Don · January 17, 2011

I don't think waiting till the car reaches operating temperature before driving off is an issue in a hot country like ours The oil is anyway roasting at about 25C so should be ready to roll nearly instantaneously lubricating the bits it needs to. Also Diesel engines rev a lot less than patrol engines, so the negative effects of lack of proper lubrication should be a lot less than a high revving petrol engine.

I'm somewhat surprised why we've come to think of Diesel as being a more expensive, high maintenance, complicated option. Before the advent of common rail technology, the basic technology behind diesels were fairly simple, due to low revs the engines should be subject to less wear, and the only little issue was that they were more sensitive to compression loss and most diesels which landed in the country had done in excess of 100K KMs though the meters said otherwise
