Hi, I'm new here!

I've got 2-3 questions that I'm hoping people might have the answer to.

1: I just installed a radio, and the Red/Black wire doesn't provide a Switched12v+ like its supposed to. I'm wondering if anyones got an idea for what wire, where, i could use to make it so i dont have to hit the power button every time i start the truck?

2: What size is the bed on these little trucks?

3: Opinion Question: My trucks red with some weird gray things down the side that look factory. I'm trying to decide what thickness to tint the topper. We're turning the truck bed into a mini-camper, as i hate tents. Any amount of tint is legal in this area.

Thanks guys :-D

 

I'm off work later today, so I'll check out on mine and report back. I installed aftermarket cruise control ain 2003 so I needed to tap into a switched circuit at the fuse box. Or, just take a $4 test light or voltmeter, open your fuse box, and see which circuits have voltage when you turn the key to "on", but not on when the key is "off". Make sure to tap into the terminal AFTER the voltage/amperage goes through the fuse. There are little metal fuse taps with male spade available (cheap) at auto parts store where you can pull the fuse, stick the adapter in, then repace the fuse. My B2200 already had a factory radio installed when I installed my stereo, so such a switched wire was already there, as was the "always powered" one which remembers the stations and presets. Are you sure there's no switched power wire there already? From the Internet:

My info lists truck bed as L x W x H (inside dimensions):
Short bed 73.6 x 56.9 x 15.6
Long bed 89.8 x 56.9 x 15.6
Cab Plus 72.0 x 56.9 x 15.6

 

I tried the switched 12v+ and it didnt work for some unknown reason... I'm gonna have my friend come over with his tester stuff i guess. thanks :-D

 

OK, checked on mine. You can always tap into the fuse box like I posted earlier. I'd recommend (1) using the 15A fuse marked "cigar" (third slot from the right, bottom) as that only needs that current when using the cigarette lighter (as a lighter, not for cell phone charging, etc., which uses way less amps)
(2) using the 10A fuse marked "meter", extreme upper left corner.
In each case, use the fuse end at the middle of the fuse box, not the one at the edges. Do not use the 15A fuse labeled "room", that's "always hot". It's probably good practice to have an inline fuse in that hot wire to the stereo. You can route this wire underneath the dash over to the radio console location; use cable ties, etc., to keep it away from stuffthat moves, like pedal levers, hand brake....

I have power taps into both of those locations on my B2200 (e.g. aftermarket cruise control on "meter"), have never blown a fuse on it, ever.
