Hey there i just installed a Airlift Wireless Air compressor mounted it ran the lines to the Ride Rite air bags and did everything but one thing . Connect it to the battery . So that being said i have everything routed have the battery connection ready to go except there is a red-white wire . Instructions say to splice into the ignition wire . Thats where im running into a problem . I dont know where to splice into .Much help is appreciated

Truck Specs

07 F-150 Supercrew Lariat 4wd 5.4 L Engine

 

By ignition wire, they are looking for a keyed powered source so that when the truck is off there is no power going to the unit.

I would find a local source depending on where the compressor is mounted.
If you mounted the compressor in the rear half of the truck I would get the power source from the trailer charge line as a source. If you are in the front half of the truck, there are plenty of unused switched sources in the fuse panel.

 

the accessory (switched) wire is also very easy to locate behind the radio if you already have been working in that area.

 

Thanks guys for all the help . I ended up taping into the radio's power source and it works great . Thanks again for all the help
