Alarm installation
 

We don't seem to have a dedicated board for electronics (ok we don't want to discuss audio, subs and neon lights on this forum, I understand that much), so I'm posting this here.

So the car alarm I had on my car (stealership quality) crapped out a couple of years ago. I popped it open and the batteries inside it had leaked all over the PCB...ouch. A few days later I bought a new Viper (the one with the OLED display on the remote) with all the extras. It's getting worse and worse by the year over here, so even though I have a closed garage now, I'm still worried when I park the car outside. I never had free time to actually install it like I would like...until this easter. I've been installing gauges etc on several Miatas locally, and I've been cursing every time I removed the kickpanel...nest of wires everywhere and a easily accessible car alarm module ziptied on the steering column. Do not want.

So I started stripping the entire interior of the car, as I wanted to install a rollbar anyway, I removed the dash and this made installing the unit a TON easier. I wouldn't even dream of doing it with the dash in place.

A few days ago:

Attachment 189439

The main unit already has a shock sensor built in. I added a dual zone proximity sensor, a tilt sensor, trunk and hood switch and auto windows roll-up on arm. I'm also connecting the 4 aux relay drivers (which you can activate through the remote) to the horn, the headlights, the dual-lock door locks (NB2 feature) and I still have one relay available - any ideas? I'm also adding the remote start feature, its nice to be able to remote start with the A/C on a hot day with the car parked outside.

Will post more pics tomorrow.

last relay should activate the flame thrower you need to install next.

That would be cool, yes. Unfortunately, I don't have a spare LPO-50 in the attic.

drats.

Trunk pop.

That's already in the standard outputs, along with door lock/unlock, parking lights (ie the flasher module). I was thinking remote kill for whatever reason. I'm already looking for ways to actually disable the ECU if the alarm is armed, in a non trivial way.

Fuel pump disable might be easier.

Reminds me of the nightmare I had to deal with the the alarm my PO had installed. That thing was the worst wiring job I've ever seen.

consider a well-reviewed add-on shock sensor. they're probably easier to tune and less likely to go off when your neighbor farts.

my alpine almost never falses due to shock. only tornado-warning storms will set it off. or lightly rapping on a body panel of course.

My favorite lame feature: windows. one button rolls both down. both roll up upon arming.

you can also set up some relays to lock-out the trunk pop and windows-down but be careful not to require the relays to be energized when the alarm is armed unless you like jumpstarting the car.

Yeah, but its the obvious thing. I was thinking something along the lines of "cut 2 out of 4 injectors". Then the car would almost catch but will never really run.

Do you really care how obvious it is? Its not like whoever is stealing ur car will try to hotwire the fuel pump.

I had a customer's car the other day to MS. He had a car alarm that disabled the starter and fuel pump. I tried to start it on the MS but it wouldn't - the starter wouldn't turn and the fuel pump wouldn't prime. The remote was out of battery. I literally bypassed both in less than 5 minutes and started the car, and I'm no car thief. All the wiring was pretty much exposed and easy to bypass.

wire it to the crank or cam sensor?

Wire it to engage your anti-lag system when armed. Better than a siren.
