alpine sec 8058 into 1992 camaro

Hi Everyone,

I'm installing an older Alpine SEC 8058 into my 92 Camaro.

I have it mostly hooked up, but trying to get some of the convenience features working.

The first I'm not sure how to do is dome light supervision. The alarm has an internal relay for this at least that's what the manual says.

The car, from how I gather it works has 2 wires Orange (always 12) and a white (appears to be a switched ground).   The wires on the alarm that is supposed to go the dome light puts out 12v. How do I hook this up?   I need it to output a ground instead of 12v right?


The next thing I'm trying to do, is use the EXT1 and hook it up to the remote hatch switch.   The remote hatch seems to work the same way. 2 wires one is always 12 and the other is ground.   When you slide the switch forward it shorts the 2 and the relay for the hatch clicks and opens the glass.

The EXT1 output from the alarm is again 12v. There is no internal relay for this option.   So I know I need to use an relay, but not sure how to hook it up, so it outputs a ground.

Thanks!
Chris

DomeLight Supervision       Blue/Red  to ground, Blue / YELLOW to the white wire on one of your door pinswitches.

Relay for hatch pop.  YELLOW /GREEN to terminal 85 of a relay.  Constant 12 volts to terminal 86 of the relay.  Terminal 30 to Ground, terminal 87 will be ground output.

Never actually played with one but weren't they a brilliant unit in their day?

I actually did end up getting them working.
I had to use a relay on the dome light supervision, because the output from the alarm is 12V.   I need it to be ground, since that is what completes the light circuit.

but here is the thing, everything works.   But both relays (hatch and the one for the light) when they are enabled make a high pitch whining noise. The stop as soon as the trigger from the alarm is turned off.

Any ideas?

Also, I was wondering if anyone knew how to do this. Not really an alarm question, but I would like to make it so the doors lock, when you put the car into gear.   Anyone know of a way to do this?   

And yes, these were pretty nice alarms for their time.   

Sorry have another question about this alarm.

I just found the start relay for it, and trying to figure out how to wire it up.   The wiring diagram has this.

Orange -> Start Cut relay.

Then on the relay there are 3 other wires, and on the wiring digram it's listed as

RED / white: Use for normally open
RED / Yellow: Use for normally close
Red: To Key

I'm not sure where in the car to tap into these wires.

There is also another wire alarm, I'm not sure if I use or not:
Red (N/O Started must be true ignition) << NOt sure what that even means.

could someone help me figure out what I need to tap into?

Thanks!

Look at page 2 of the PDF file that I posted earlier.

Yes this is the sheet I've been using and where I got the descriptions I posted.

but I'm not sure where on my car that each of those wire I listed above actually connect too.

Red N/O started MUST be joined to an ignition wire that stays live during cranking: TEST
In fact that's an obligatory connection otherwise you could turn on the alarm whilst driving.
Then from the relay, cut the starter wire, red to key side and RED / yellow to starter side.
Don't use RED / white. You can but I prefer the extra safety of normally closed.

You do not need a relay for domelight supervision.  If your vehicle needs negative, you ground one of the 2 associated wire, then use the other wire to give yoiu ground out for the vehicle.  Chances are, you applied positive voltage to the wire.

x 2 with Mr. I look at the diagram again. And forget about locking the doors when you go into gear, you would either need an auto with a warning light for each gear like Honda or Mitsubishi and a relay with timer e.g. DEI 528t, or if manual a Hall effect switch or microswitch at the gear shift, good luck with that one!
Or a clutch switch if manual.

When you say, use the other wire.   There are 2 wires, the blue / YELLOW   and the fused blue/red.

If I hook the blue / YELLOW to ground, the blue/red outputs 12v.

Are you saying to swap them? Because I tried that, and the blue/red blue the fuse when I did that.

So the Red N/O during starting is 12V and nothing any other time correct?

When you say extra safety of the normally closed, what do you mean?

Normally closed means you will still be able to start the car if the alarm fails.

Have you read the instructions? The auto lock doesn't work for the first 30 seconds so connecting to the gearshift isn't relevant.
Also the blue/red should be grounded and the blue / YELLOW to the door trigger, though don't forget this alarm is X years old.
So the red N/O during starting is 12v+ and nothing any other time?
Are you actually reading this or listening to what I said which was;-
Red N/O wire must be connected to an ignition wire which stays LIVE during cranking"

What's with the attitude?
I had some final clarifying questions, sorry if I was upsetting you.

Yes I have read the wiring diagram but was having difficultly understanding where to tap into my car. I thought it would be best to make double sure before actually cutting anything. Maybe there was someone else on this forum who has a Camaro and knows exactly the colors of the wires on the car and where to locate them.

Thought that was what this forum was for, to ask questions and get help before when you're in doubt.

I know this, but was just wondering if the gear selector was possible. It was just a question, maybe someone had done this before. I have this feature on my truck and it's nice.   You can warm the truck up, while waiting for the passengers etc.   If it's not possible no biggie, but no reason to get an attitude.

Mods, just delete this thread.   

Sorry if I came on a bit hard but what Mr. I said about the dome supervision was correct, it appeared that you weren't listening or hadn't noticed the 30 second locking.
What you said about your truck is probably correct but as I pointed out installing the means to do this as a retro-fit is beyond most people.
I'll try and post the DEI instructions for this vehicle, let you know if I succeeded in a few minutes.

Initially, did you have the blue/red or the blue / YELLOW connected to a positive 12volt source?   That pair of wires control the domelight supervision.  If your vehicle needs positive voltage to illuminate the domelight, you would connect one of these wires to a positive voltage source, then connect the other wire to the vehicle's positive domelight trigger wire.

Since your vehicle requires ground to illuminate the domelight, you need to ground one of those wires and connect the other wire to the white wire that can be found at either of the 2 pinswitches located in the door jamb.
