Where to buy a single T-Tap to hardwire my detector?

[category4]

Never use t-taps, they are the worst invention ever. The only proper way to tap into a wire is to take the original wire, strip some of the insulation off, take the new stripped wire and wrap it around the other. Apply some paste flux and solder it. Once cooled apply liquid electrical tape following the instructions. Once that is done you can apply some regular electrical tape for extra protection.

That's the way I was taught years ago. Now I just like using the add-a-circuit fuses. Those T taps can give you loose connections, cause voltage drops, etc. But if it works for you go for it.

add-a-fuse is fine if you are tapping power but sometimes you have to tap into a signal wire coming from a sensor or the PCM, so doing the way I said is the only way to get a reliable connection and not worry about messing with the signal.
