HiTech Mobile Security HT-455

Hello everyone, I'm new to this and hopefully I'll be helped as soon as possible. I want to thank you all in advance for help that you are providing.

I purchased HT455 Car Alarm system which I already saw is not very popular from members of this forum. I believe that I connected everything properly but I'm not sure for few wires. First of all I didn't connect wires for Windows and Trunk.  Wires that I'm questioning are WHITE/ blue wire (from car alarm) that goes to Engine Cap (I believe in other words its Ignition coil which I connected to "BLACK / YELLOW collor).  Also another one I'm not sure about is Negative Door Switch. It is green collor on the alarm that I connected to WHITE/ black one in the car.  Plus Door Switch I didn't connect anywhere because I didn't know if it needs to go enywhere at all.  Also I didn't connect BLACK/ white wire that says it goes to open dormer cuz I wasn`t sure if that is something to do with windows or not. The thing is everything works "almost perfect", but my problems are following:

1. When I was testing the alarm, if someone opens the door alarm does goes off, but I was still able to turn on the car and that didn't happen with my old alarm. Also that Override switch doesn't do much to turn off alarm if I don't have keyless remote.

2. When I disarm the alarm and enter the car alarm arms itself soon afterwards and in another 30 sec at most it goes of in the middle of the driving.  This was strange on my test drive.

3. Last, but not least is my main light in the car, one that goes on the top of the roof doesn't shots off for some reason.

I would be very gratefull for anyone that could help me finishing my first project. I thought saving $100 would pay off, but apparently it gave me lots of grief.  Thank you all once again and I will be expecting someone to answer my question!!

Ok I will definetelly disconnect the engine cap wire from ignition. Only yellow wires were thick ones that goes to the ignition (wire from the middle of the relay) and another one (side of the relay) that goes to power source. I own 1999 Civic LX. Thx Daz for your help I`ll be expecting your reply.

Hi i have bought this same alarm, and have been trying to work out the crap wiring diagram!! I plugged it all up of the car using dummy loads and can get it all to work except i cant get it to fire my central locking? Any ideas? I spoke to my uncle who is a master technician mechanic who cant work out the diagram either as its nothing like he has seen before! He said that in the drivers door of my car it is only a switch that fires the passenger door lock, and that i need another motor, prob is it wont fire the spare motor?

Any help would be much appreciated!!

Cheers Adam

Hey Adam

I was just wondering which car do you have. If you have car with power locks you shouldn't need any spare motor of any sorts. I agree with you that diagram is crapy as it can be. In my civic I found 3 wires on the side. On the side of your left foot should be something that you can uncover and take a harnes apart wire by wire. There should be 2 wires for your lock/unlock and wire for central lightning. All of them are I believe green in my case. SOme has white on them some brownish. What you need to write is your make of the car and We might be able to help.

Hey Daz

Daz I`ll try to fix it first thing in the morning. I put negative wire on WHITE/ Black wire in the car and that might have given me some problems. Also thick wire I did cut and connect it with those from relay, but I didn't connect thiny one that goes from side of the relay. Thank you for your help and I'll come back here to tell you if it worked.

In overall I think that this alarm is not so bad but instructions are the worst I ever read. Some pages are also repeating. On the box it says that it has 6 tones, but I don't have pages for programing them  or programing almost anyhing. Thx guys see you later.

adam, 

The alarm is negitive triggered and your car is more then likely positive triggered and you would need to hook it up like this.

Sorry i was trying to up load a pic and it didn't work.
