5V to starter relay trigger?

[JSchuricht]

Got stranded at Best Buy. Hit the remote start when I came out of the store, heard fuel pumps running when I got close enough, but no starter engagement. Checked all fuses, bypassed alarm/remote start with no luck. Checked the starter wire Red w/ lite Blue stripe (under dash) and brown w/ red stripe (under hood), it has 5v constant. Truck runs fine if I jump the starter relay. I don't have a wire diagram, but I would think that the starter relay trigger wire should be getting 12v during start rather than 5v constant.

Other things checked.
No other wires going to the ignition switch have 5v regardless of key position.
5v remains on when harness disconnected from ignition switch.

Update...
Still not sure why there is 5v on the line, but found the relay to be bad. Decided to go a different route for the repair. Ran a new wire from the starter solenoid to the relay on my remote start now the truck can't be started from the key or by jumping the relay under the hood.

So...what happens when the battery on the remote goes dead? Or if you lose the remote?

I have two remotes, and keep spare aaa batteries in the cab. Yes, it dose make things difficult for troubleshooting, but should help to keep the truck from getting stolen.
