Along with what gauge wire and what fuse, I need to know what type of wire.
Like, can I get regular automotive wire? Where can I get that? I'm going to Advance Auto Parts tomorrow morning to get these things.
So.. gauge wire... I have no idea what to get.
And... Amp fuse... What fuse should I use?
Also... what type of wire?

Stranded copper wire
18 ga would be fine (see below)
5A fuse should be fine for that solenoid
Look at the chart on the link posted by ardwrkntrk above and you can see the maximum
amperage ratings for the various wire gauges.

25A is WAY more than you need to activate a solenoid.
It's also more than 16Ga wire is rated to carry.

I'm saying don't fuse it at a higher amperage that the wire can safely handle or the wire becomes the fuse.
You shouldn't need more than a couple of amps to pull down the solenoid.
If you're so intent on jury rigging your truck it would probably be easier and cheaper to just run some zipwire up the PS fender, through the climate control area and across the dash to where you want it switched.
Drop a SPST-NO momentary switch across the end. (either button or toggle)
At the other end connect one lead to the S terminal of the solenoid and other lead to the fuseholder.
Connect the other side of the fuseholder to the hot terminal of the solenoid where the battery cable attaches.
At least if the wire is paired you only have to pull it once and it's less likely to become tangled.
Since you want cheap, buy some lamp cord at the BigBox, it should only be pennies a foot.
You're going from the same exact spot anyhow....

Well, I have to get 16 gauge wire for my new speakers...
So, I can use speaker wire for the ignition? Too bad that I can't use 16 gauge wire for the ignition, too... Oh well.
Okay, I need 18 gauge wire for the ignition.
And for the speakers, 16 gauge wire.
