Installing my Laser Diffuser today. Electrical hints appreciated!

[JEFF4507]

Hey guys,

Finally got a day spare and will install my Lidatek LE-30 to the front bumper of the car.

Hopefully I'll be able to get away without removing the bumper completely, but I'll do what needs to be. However, the part that is a bit intimidating to me is the wiring section.

I need to locate a positive and negative that are enabled when the ignition is turned, and an earth. It has a switch on it, but am not sure about drilling it (along with the LED) into the dash just yet, and may settle for leaving it under the glove box for now.

But any tips on which circuit to wire it into, I'm told it doesn't use much current, or is this irrelevant ?? Physics GCSE was a while back !!

I assume it would be best to keep the actual central unit in the car out of weather's way (the transponder is water proof and warranteed against lens damage). What would be best to seal the car afterward ?

If anyone's done this before I'd very much appreciate any help. (Kwik Fit, Halfords etc won't touch it)

Yep I've installed my old Target LRC100 to my Trophy.

You don't need to take the front bumper off, just remove the front grill for better access.

I've got mine plugged into an Origin b2 (makes life easier).

Brilliant stuff, how have you got it wired ??

Does yours draw power from the B2 ?? In which case, what's the B2 wired to ?

Any fitting tips will be grand, I'm going out in a second to get setup.

The LRC100 plugs into the wiring loom for the Origin b2. I took a live feed from the cigar lighter for the b2.

The LRC100 is attached to the car with extra strength outdoor felcro stuff from Halfords.

Hope all goes well with the install.

Hmmmm.

How did you manage to remove the grill without the bumper ? Looks like it's joined at the bottom.

Where abouts did you route the transponder cable ?

 

[JEFF4507]

Ok guys, the interface box is connected, and the only thing left there is to drill two holes somewhere for the switch and the LED.

Wiring wasn't the easiest thing in the world, luckily my unit has a fuse fitted otherwise I would have blown it up....

Anyway! On a lighter note, I just need to route the cable from the transponder from the engine bay (it's currently wrapped around the right strut mount, into the passenger compartment. A friend has suggested through the bonnet release, any pointers ?

When this bit's done, all that needs doing is taping the actual transponder down (it's not really fixed atm...) and then to drive along, knowing that laser using ****s can only get me from behind... For now

Just be careful they don't pull you over and go over the car! :S lol

 

[JEFF4507]

Lol. They wouldn't find it if they did my friend, that;s the beauty of the Lidatek, it's so small. And my control box is burried under the cigar lighter. Just need to fit the switch and light in a discreet place.

But back to topic:rasp: How the frick do I get that cable through ?

 

[Paddy_g46]

wat is this thing ur fitting? lol

 

[The Hoff]

Any chance of getting some pictures of this unit both boxed and fitted Jeff? Im intrigued.

wat is this thing ur fitting? lol

It stops Mr Policeman getting a laser speed reading on your car

cool i like the sound of that

Sure thing, when looking this morning, I found little to no info on the stages that were required. I suppose they're fairly simple in essence, so the people that would buy this kind of thing wouldn't have any trouble fitting it. But I've never been a fan of breaking things I haven't fixed before, or having any backup.

But it's all working now, apart from that one last step !! I could drive round with the cable coming up from the bonnet and through the passenger window, but I won't.

I have been taking pics of the different things I've done, installation can obviously be as discreet as you like, anyone inspecting it would never be able to find it unless they were looking and took the car apart. The Lidatek also shuts itself off after 5 seconds of jamming, allowing the laser trap to get a reading on your car for the second try. This means they'll be less suspicious of a block, and put it down to ambient conditions. Lesser units will be on constantly and will jam laser signals till the cows come home, but obviously this will get you into trouble sooner or later.

You may say that 5 seconds isn't long to slow down, but it is really, say 1 second reaction time. Pedal to the floor (braking of course). And you have 4 seconds of braking time. Unless you're about doing 100mph in 30mph zones, you should be just fine with that. The unit has a deafening 100db alarm, I have mine in the centre console and it's startup chirps are still very loud, so I'm both nervous and anticipating my first laser attack, one because I'll need ear surgery, and two I want to make it worth it's money!

If you think about it, it only needs to go off once and it's saved you money. I got mine 2nd hand from ebay, but new they're £300.

 

[The Hoff]

Would it work if you shine a laser pen at it?

 

[JEFF4507]

I couldn't say, I don't have a laser pen, but I'm sure police trap lasers have a few extra gibblets than a £5 toy...

Though I wouldn't put it past them.

 

[JEFF4507]

After looking very strange in my car for 5 minutes, I have found the grommet for the bonnet release cable.

How do I get it out ? Push it from the passenger side ?? Will it be ok with another cable of equal size being routed through ?

 

[7MAT]

You can test it with a mobile phone, just send a business card via ir and have the phone 1cm away from the unit.

 

[GordonD]

A laser pen should not trigger it. The frequency is completely wrong. Pens are optical, so you can see where they're pointing to. Laser guns are infra-red, so you can't see them. Whether a mobile phone with irda on it works depends. Radar guns are 904 nm wavelength. Irda is 875+/-30 nm.

 

[JEFF4507]

Indeed, my phone didn't set it off. I tried my Yamaha receiver and Xbox360 remotes on it, and the only button that worked was the Power button for my DVD on the Yamaha remote.

Bit complex I know, a few other buttons set my Bel550 off though, guessing it picks up a broader spectrum.

Either way, the unit is in now, ended up sticking some mastik on it. It's a bit more visible than I would have liked, but it's there and it works. Now to find a police speed trap to test it for real.
