12v Constant and switched
I recently did a complete Stereo install, and for my head unit to keep it from restarting every time I turn off the car I need to wire a constant source, the previous owner had a hot wire coming from th Wiper fuse and that's where the Red and Yellow 12v wires are connected to at this moment, are there any locations that I can use to get a 12v source so when the truck is off I don't lose memory? Thanks in advance, also I have a 1998 F150 XLT 4.6l if that helps

Theres several
On my 2003 they were on right side of my fuse panel
What things work without igntion?
Interior lights
Doorlocks
12v plug sometimes
Etc
Look at owners manual diagram, pick one
Use add a fuse to tap it

The factory radio harness has a constant 12v+ wire in it.
For al of your wiring needs.

I wanted to use the 12v Plug aka cig lighter, but I don't know how to tap into it as well as getting my hand in there without taking the entire inner panel off, but I will also try the Fuse method, also I have a feedback issue with my ground, I grounded it to the chassis but its still there, should I run a ground loop?

From the link I posted the 2 wires you need are in the factory radio harness behind the radio. green/ purple is constant hot for radio memory. Switched power is black/pink
