avistart 4100, ’06 vibe, accessory wire?

you said "RED / blue" but i hope you meant "blue/red" for the accessory wire on your 2006 vibe, because it's a blue wire with a red stripe.

There is an orange heavy gauge wire (30A) from the Avital that you should have connected to the blue/red wire of the Vibe:

There is a RED / wire (thin gauge wire) H1/7 from the Avital that is a -200mA signal that should connect to the blue/white wire of the Vibe.  However, i would connect this wire to a relay and let this signal relay a grounded signal to the blue/white wire so you don't accidentally blow a transistor on the avital circuit board.

did you voltmeter the blue/red wire of the Vibe with the key in ACC and ON positions? If so, what voltage did you get?

I would voltmeter the orange wire separately (disconnect it from the blue red wire) and verify that it's outputting 12 volts.

I see what you're saying -- so when you r/s the car, the blue/red is getting 12 volts from the r/s brain.  Hmmm....

Two igntion wires .. are they both hooked up? 

Here's is *pdf file that on page 2 shows that there is only a blue-red wire that supplies the accessories:

Do you have BOTH igntion wires hooked up?  If not, your accessories may not work. The one you need to specifically look at hooking up is the BLACK-YELLOW wire (thinner gauge wire) .. this is part of a relay system that provides power to heater, accessories etc along with the blue/red wire.

Yeah -- just get a relay and wire as follows:

85: 12 volts fused +

86: remote starter output wire (RED / white) -

30: chassis ground

87: blue/white wire at hatch switch

Also, meter this RED / white wire to make sure it's dropping to 0 vdc (ground) when the trunk output button is triggered (must hold trunk button for > 1.5 seconds)

Anti-grind -- yeahp... simple as it looks -- lemme know if you have any issues with it.

best of luck
