Help! 5th Gen wiring SwitchPros 8100 install

[krelnydelnky]

Hi all,

I recently purchased the SwitchPros 8100, and everything is just groovy, but I am running into a problem installing the blue (switched 12v power) wire and the yellow (dimmer) wire.

They supply a backpack fuse for the switched power wire, that I would love to tap a fuse under the hood - however i haven't found anything that i can tap into and I would rather not tap into the EFI fuse - would rather a spot that has the least amount of things to go wrong. I currently have a switched light accessory on my 10A INJ (LED lights in the front).

I have seen [MENTION=44152]Ronin[/MENTION]s build where he taps into the A pillar, to an empty fuse loc, but the fuse cover won't go back on if thats the case and I also really don't want to go back through the firewall with this wire (but will if I have to).

here is a picture of the fuse box under-hood and you can see where i have already tapped with a backpack fuse

and a diagram for reference

As for the yellow wire, going to a dimmer, is there a cleaner way to tap into a headlight or parking light that isnt a T - Tap? Currently open for opinions on this.

thats all for now, looking forward to hearing your feedback, and thank you SO much!

Just curious as to why it matters if the fuse cover can't back on?

In regards to the wires, I ran both my ignition and dimmer wire through the firewall. For the ignition, I tapped into a blank circuit and for the dimmer, I tapped into the headlights. If you want to tap into the actual headlights, then go with the posi-taps. The t-taps are a big no-no in my book and will never use them especially on factory wiring.

Here is a link to the posi-taps. Pricey but better than cutting into your factory wiring.

Good luck with your install!

Thank you!! As for the cover, I can get over it, its just a neurosis thing.

And thanks for the link and info for the posi taps, haven’t seen those before, but damn do they look easy.
You tapped into the headlight in the cab? Where did you do this?

Thanks again!

Heres a picture of where I tapped into on my fuse boss. Picture is upside down. I don't like tapping into factory wiring.

ahh so you did two backpack fuses. I like this a whole lot better than tapping a wire.

Okay, you may have just sold me on that. Wish there was a way to keep the cover on, but ill get over it.

thank you so much :hello:

The top one (blank above KDSS) is the ignition and the other is the dimmer (taillight). Good luck and let us know how the install goes!

Guys, I’m stuck with the step for the ignition power. All of the Toyota fuses appear to be constantly hot, that is even the accessories that only run with the engine running are hot at the fuse. Toyota basically uses the fuses as the ground. Has anyone been able to wire this up, per the instructions, to a line that is actually linked to the ignition? I’d like to avoid creating a relay just for this.

I tapped mine into the fusebox by the footwell as mentioned above in this thread. Just look a few posts up.

I read those responses, but I don’t believe that you’ve followed the instructions completely. The fuse box you are referring to is always hot and thus doesn’t satisfy the requirement. I ended up calling switch-Pro and they advised t-tapping into the green wire for the 12 volt accessory plug in the dash.

There are plenty of slots on the fuse box near the footwell that is not always hot. Use a voltmeter. I have mine wired up this way and I cannot turn my lights on without the key in the ignition. If switch pro told you to t-tap then go for it but know that using t taps, you are essential cutting the wire and a factory wire at that. Good luck with your install.

Mine is installed correctly, thank you for the concern lol. Plenty of fuse slots that aren't always hot.
