Power source in Trunk - That goes On w/ ignition switch ??

[jamesmost]

I need a power source in trunk that goes on and off w/ ignition switch ???Do i have to run power from fuse box ?? or is there already a source in the trunk ??or a source closer to trunk ??

[Jesda]

Fuel pump?

[qship96]

without knowing how many amps you need to draw,how can this question be answered?

[jamesmost]

not touching fuel pump power or power to cd changer.Prob. max 15 amp draw

How about power to the attenae motor?

How about power to the attenae motor?

I like that does it only get power when radio turned on ?? or when car turned on

[bullittandy]

On my 97 the power antenna only goes up when the radio is switched to FM/AM but is DOWN on CD and Tape (discovered this hooking up an amp)

[lakeq45]

Are the Bose speakers in the Q like those in some other cars where each speaker is individually amped? If so, they may have a hot wire running to them.

[pito11213]

I think it is operated by the remote wire on the radio. Do you have a stock radio?

[jamesmost]

yes stock

What you can do is grab the power antenna wire behind your radio and cut it off from the harness going into the radio.

Now that one wire yoru holding, will be a wire that goes all the way to the trunk/power antenna. Now grab that wire, and splice it into the accesory/ignition wire on your radio, OR back to your igntion cylinder harness.

Then the power antenna wire/power antenna will be ignition/accy powered

but the antenna will go up whenever u turn the car on ??

Find a wiring diagram and see if the "factory" trunk mounted phone brain was pre-wired and is of sufficient gauge.

I thought it was to the left of the FPCM, but it's not shown in this illustration.Click

Yeah, but in the world of XM, you can just disable the antenna completely.

I do not live inthat world nor do i use my changer still dont want to mess w/ it

I think i still have all the goodies from the phone system will look at that or just not be lazy and run some Wires from fuse box

[qsiguy]

Your best bet is to run a wire from the fuse box or the ignition switch harness with a 15-20A inline fuse. There might be a few power wires back there but if you are really going to draw 15 amps I doubt any of them would be safe to use. I doubt any OEM circuits back there have 15 amps extra capacity built in from factory. I wouldn't hardwire the power antenna to ignition because if you went through a car wash you couldn't put down the antenna manually unless you also added an on/off switch to that wire up front. The power antenna will have a contant power wire and one that turns on/off with the radio. Cell phone box will prob. have a constant and and ignition hot but it's likely only 10A.

I don't think I'd use any OEM circuits for more than about 5 amps continuous.

Checked out the trunk wiring when I got home tonight and I took a photo of the cell phone plug/wires. Here's a photo. The two larger red wires are constant 12VDC+ and the smaller blue wire is switched ignition 12VDC+. The switched wire I wouldn't try to run much with but you could add a relay to switch the power from the larger red wires with the blue wire. The blue wire would only have to turn on/off the relay (.5 amps+/-) and the relay could in turn control up to 30/40 amps. I can supply a diagram for this if you need one. The common SPDT relays I use have 5 terminals all numbered. Wire #85 to ground, #86 to the blue ignition wire, #30 to one of the red constant 12V+ wires and #87 to your accessory, and #87a would be unused. This would turn your accessory on when the key was switched on.

I have my remote wire for my amp tied into my fuel pump if that helps at all.

[jamesmost]

Fuel pump?

if i choose this route where should i tap off the power?? will it effect draw on the pump ?? i am hooking up a small compressor otherwise i will take the power from the rear cigarett lighter (not used anyway and 20 amp) the compressor calls for at least 15 amp and came w/ a 20 amp fuse)these horns are gonna be really loud, I MEAN REALLT LOUD

[elwesso]

You know probably the easiest way would be to use that cell phone trigger wire that was mentioned earlier. Run a small wire from your battery all the way to the trunk and then hook it up to a relay via the trigger.. Should be simple.

I wouldnt want to draw off the fuel pump... BAD idea!

I concur about the fuel pump. I wouldn't touch that.

If you are going to the trouble to run a wire from your battery I'd just run a few more spares from the dash area while your at it. When I install a big system I almost always run a couple extra while I'm in there for future enhancements. Once you have a high current 12 volt supply back there you only need small wires to control relays and you can do almost anything you could ever need to do in the trunk.

i ran a fresh line from the fuse box 30 minute jon used 12 awg hooked into rear cigarette lighter fuse.my new train horns @ 120 psi are insane, really not for sane humans.gonna secure the air hose 5/8 id under the car tonight

[qsiguy]

So that's what you've been working on! Train horns are crazy. There are some clips on streetfire.com of people scaring the heck out of people with those. Super funny stuff . Search for "horn" on that site and you'll get a bunch of clips.

thats where i learned about them. the first set i bought were way too big to fit under the hood. found a set designed to fit under hood. sold the other ones \. it is funny, gonna get arrested though, eventually

will get some video next week, wife and kids away w/my camera. yes i am all alone mmmmmmmmmmmmmmmmmm also getting a bigger solenoud valve get a little more volume

yes streetfire.net

OOPS, my bad. I look there almost every day, you'd think I'd have caught that one.
