Installation of Avital 2200 Alarm

Hello everybody I’m a new member of the forum.

I am installing an Avital 2200 alarm and 508D proximity sensor in my 1999 Miata. To get started, I am only doing the wiring for the most basic functions: Door switch pins, shock sensor(built into alarm module), and proximity sensor. As far as I can figure, I have to splice or tap into the following wires:

1. H1/9 - yellow wire from alarm module tapped or spliced into Ignition 1 RED / black wire in Ignition Switch Wiring Harness.

2. H1/5 - green wire from alarm module spliced into WHITE/ red(-) Door Switch Pin wire in Left Kick Panel.

I have other connections also:

1. 508D green and blue wires connected to H1/6 - blue wire from alarm module.

2. 508D red connected to 12V(+) constant power fused.

3. 508D black connected to chassis ground.

4. H1/8 - black wire from alarm module connected to chassis ground

5. H1/10 - brown wire from alarm module to red (+) wire on siren.

6. H1/11 - red wire from alarm module connected to 12V(+) fused constant power.

I have a couple of questions I hope someone can help me with:

1. How should I splice in to a wire? I have some blue plastic connectors that allow tapping into a wire. Is there a better way?

2. Do my wiring connections seem OK?

3. How should I mount the alarm module? I was thinking of using double sided tape to something rigid, but the instructions say mount it to a wiring loom?

Any comments or suggestions will be greatly appreciated. Thanks.

Make sure you "cable tie" the unit to a medium size wiring harness, the unit works best when it is slightly loose on the harness.

As some of you may know, I am installing an DEI Avital 2200 Alarm with 508D proximity sensor in my 1999 Mazda Miata Sports Package. I have bought a Digital Multimeter (DMM), and I am learning how to use it. My question concerns the door trigger wire. I know from information gotten at this site and one other that it is a negative trigger, the wire is WHITE/ red (white wire with red stripe), and it’s located in the driver’s kick panel.

On the driver’s kick panel, I see a harness coming out of the rubber boot on the door. I suppose the trigger wire is located inside this harness? Next I know that the following conditions exist for (-) and (+) trigger wires:

(-): 12V door closed/ 0V door open

(+): 12V door open/ 0V door closed

I want to check my logic regarding the use of the DMM checking the trigger wire for (+) or (-). Assume one side of my meter is probing the trigger wire and the other side is touching ground or grounded. When the door is opened the interior light comes on and vice versa. Then the following must be true:

(-): With the door closed, the door switch is open and the DMM reads 12V, since the circuit is completed to the car’s battery. With the door open, the door switch is closed and the DMM reads 0V since both sides of it are going to ground or the potential across two grounds is zero.

(+): With the door open, the door switch is closed and the DMM reads 12V, since the circuit is completed to the car’s battery. With the door closed, the door switch is open and the DMM reads 0V since the circuit to the car’s battery is open.

Does that sound right?

As an addendum, I thought I had better describe the (+) and (-) circuits, so you know what I’m referring to:

(+): 12V battery, door switch, dome light, and ground

(-): 12V battery, dome light, door switch, and ground
