12 Volt Power Outlet Question on RT-S

[stewartj239]

Looking at the manual, the 12 volt power outlet that is in the frunk is powered by fuse #6 (by default) and only provides power when the ignition is on. Moving it to fuse #7 will provide constant power even when the ignition is off.

I would like to power the Dyno Jet AutoTune module from what I think should be fuse #6 as opposed to drawing power from the tail light wire - which I understand is not adequate. Here are my questions:

1. Can fuse #6 and #7 both be used simultaneously or is it an either or condition?
2. If the answer is yes, then should I move the existing fuse from #6 to #7 for the 12 volt power outlet and use a fuse tap to tie the AutoTune into fuse #6?
3. If the answer is no, then can I use a fuse tap at #6 to power the AutoTune without affecting the 12 volt power outlet?

1. No. It is either, not both.
2. Won't work see (1.)
3. I think that could be done.

There are lots of places to tap into a wire that is hot when the ignition is on,,,if you don't need much amperage. Taillight wires, clearance light (fender) wires, gauge lighting wires, passenger heat grip lighting wire, and the list goes on. I wouldn't mess around at the fuse box unless you have added an auxiliary fuse block wit relay switching. JMHO

The reason I am looking at the fuse box is because of this thread:

http://www.spyderlovers.com/forums/...hank-you-spyderlovers&highlight=fuse+autotune

The AutoTune was hooked into the tail light wire but it did not provide enough juice and they had problems. They ended up tapping into the fuse box. This thread talks about doing the same thing.

I guess what I'm looking for is what is the best solution for powering the AutoTune. If I can use the fuse box, I wasn't exactly sure how to wire it. If hooking it to the tail light wire is the way to go, then I am not clear on where to find that wire or what color it is. Those details were not provided in the installation instructions.

That indicates a subtantial current draw. If you wish to have your trunk outlet powered all the time, your best bet would be to install an auxiliary fuse block powered by a relay tapped into the lighting wires. The Eastern Beaver 3CS would be a good choice, but there are others.

Right now, I do not use the trunk outlet at all. billybovine indicated that I could use a fuse tap to tie the AutoTune power into the outlet power. If I did that, I assume I would just need to be careful to not overload that fuse???

If I went the Eastern Beaver 3CS route, are there any step-by-step instructions that you can point me to? I am good mechanically, but VERY weak when it comes to the electrical stuff

If you do not use the trunk outlet, just put the fuse in slot #6 and tap into either the front or rear outlet harness. You can even do this near the fuse box if it suits you. I would not use a fuse tap...they tend to cause problems. I would fuse the line that runs to your fuel controller if it is not alreday fused. Fuse it as close as possible to where you make the tap.

Not being comfortable with electrical work, you might want ot solicit the help of a friend or find a friendly technician that doesn't mind modifying a Spyder. Sorry, no instructions with the 3CS.

Before I continue any further, I have sent an email to Dyno Jet tech support explaining the issue that resulted from using the tail light wire and if using the fuse box was a better option. If they still advise to use the tail light wire, then I will probably do that. I'll let you know what they say. Thanks.

Good Luck! :thumbup:

After giving it more thought, I would not advise using a fuse tap. On the 2013s the fuse boxes are exposed to a lot of water in their location behind the front trunk. You wouldn't think so at first look but the do during washing and in the rain. They are really well sealed so trying to run another wire in it would break the seal. Using that circuit is fine, just somewhere else. It is a 16 gauge wire with a 10 amp fuse so there is lots of power.

Yup. You're right. I just took a look at it and the fuse box is tightly sealed. I guess that idea is out.

I guess I will just tap into the tail light wire just as Dyno Jet recommends and hope for the best. The AutoTune will be installed under the seat next to the PCV. Can someone direct me to where I can locate the tail light wire from that area and what color it is?

Just to follow up on this. I did hear back from DynoJet today and they said that using the taillight wire should work without issue. They did say that drawing power from the fuse box is fine as well. There is no advantage to one over the other.
