so i can remove all this crap yeah? is it the white box in the second pic?

can you circle the bits in the pic that are related to the alarm. ie. that i can remove safely. is the silver box related to it too?

silver box is part of the car. it should be the main central locking unit in that car. anything attached to the white box can come out.

if it ties to something in the main harness clip and tape it. the alarm is alpine based.

Without a dout it is not stock..

Those connectors are not used as stock item as far as I know.. I have seen many of these used in Head unit and alarm installations from japan. They dont do the "strip te wire, wrap it around another stripped wire and wrap it in electrical tape" that many dodgy backyard jobs here in aust. do.

+1 for alarm.. see the metal brass coloured thing.. Im going with that the "siren" bit of the alarm. Explains why there it doesnt go anywhere else..

If it ws hiden under the factory air box makes it alot more difficult for a theif to locate it due to its unusual location plus they need to remove the stock airbox to get to it and remove it. I have never stolen a car.. but I am asuming that you need to disable the alarm somehow.. what better way than just cut the siren off?

Hey guys, new to the forum, first post, sorry if this thread is old...

I have just bought an R33, the alarm siren doesn't work, I am trying to get it going...

The siren looks exactly the same as the one in this thread located in the engine bay aswell. I have tested the siren - it works ok.

It has 3 wires attached to it - red, yellow and blue.

Yellow has constant 12V on it, red and blue have nothing. I thought blue would test continuity to ground but it didn't.

Traced wires back to inside under glove box. The boxes are the same as the pictures in this thread. The blue wire goes to the metal box, and the yellow to the plastic smaller box.

The red wire i haven't traced back yet as the wire goes over to the drivers side under steering wheel column.

As i cant afford to pay for a new alarm system which i want to get down the track anyways, i would like the siren to be working in the meantime...

Any advice on what i can do?

I would like to know what the 2 boxes are for? Im guessing maybe the metal box is for central locking?? It has 2 relays inside. I can post pictures later of the inside.

The remote for the alarm seems to be a brant system, but these 2 boxes look like factory parts? Bit confused...

Anyways any help would be appreciated...

Thanks,

James

      Did tie rods. Steering now not "springing" back.

      Yep, there's a very minor drift left that happens a few seconds after letting go of the steering wheel, but not enough to bother me. Enjoying the car still!

      Steps to DIY sanding car back ready for respray....

      Sounds good.  I don't 100% understand what your getting at here. When you say, "I keep seeing YouTube videos where people have new paint and primer land on the old clearcoat that isn't even dulled down" do you mean this - there is a panel with factory paint, without any prep work, they paint the entire panel with primer, then colour then clear?  If that's what you mean, sure it will "stick" for a year, 2 years, maybe 3 years? Who knows. But at some stage it will flake off and when it does it's going to come off in huge chunks and look horrific.  Of course read your technical data sheet for your paint, but generally speaking, you can apply primer to a scuffed/prepped clear coat. Generally speaking, I wouldn't do this. I would scuff/prep the clear and then lay colour then clear. Adding the primer to these steps just adds cost and time. It will stick to the clear coat provided it has been appropriately scuffed/prepped first.  When you say, "but the new paint is landing on the old clearcoat" I am imagining someone not masking up the car and just letting overspray go wherever it wants. Surely this isn't what you mean?  So I'll assume the following scenario - there is a small scratch. The person manages to somehow fill the scratch and now has a perfectly flat surface. They then spray colour and clear over this small masked off section of the car. Is this what you mean? If this is the case, yes the new paint will eventually flake off in X number of years time.  The easy solution is to scuff/prep all of the paint that hasn't been masked off in the repair area then lay the paint.  So you want to prep the surface, lay primer, then lay filler, then lay primer, then colour, then clear?  Life seems so much simpler if you prep, fill, primer, colour then clear.  There are very few reasons to go to bare metal. Chasing rust is a good example of why you'd go to bare metal.  A simple dent, there is no way in hell I'm going to bare metal for that repair. I've got enough on my plate without creating extra work for myself lol.
