I have an '08 Malibu V-6 and need to install a couple items to be switched by ignition. I am in need of the proper point to obtain ignition controlled power to operate a relay. I have searched but have not located an answer to this question. If someone could provide the information, I would greatly appreciate it.

Thanks,

Radiostrobe

What are you installing by ignition switching? It all depends on how many amps it is going to pull. One relay might not do it.

I am looking to use the ignition sense on a two-way radio to power it on and off with the ignition and maybe an accessory outlet to be switched also. The total would be less than 10 amps.

I can't remember how big the ignition wire and 12volt wire is off the top of my head. Here is the info for those 2

Battery RED / WHITE (+) IGNITION SWITCH HARNESS
Ignition 1 PINK (+) IGNITION SWITCH HARNESS

If the pink ignition wires looks like a 12ga go ahead and just tap in there.

If it is smaller like 18ga, but the 12v looks like 12ga use a relay with this info to power up your sources just to be safe.

85 ground
86 ignition wire (Pink)
87 12volt constant (RED / white)
30 output wire to your accessories.

I looked it up while at work and the best option is to hook it up to the ignition wire pink on the cylinder, and fuse your connection.

If you want to make it a little safer there is actually a 50A handling 12v+ power wire in the BCM which is in the center console. You could hook a relay up there for sure. Just find a ignition wire to turn on the relay or run it from the ignition switch down to the bcm to switch your relay.
