Recently bought a uniden r3, am in the process of installing it to a motorcycle. Was wondering if this is the hardwire cable, And do I just connect it straight to the battery? The positive and negative wires are quite thin so thought I would double check.
Any help appreciated thanks!

I personally have never seen a Uniden hardwire like that. Where did you purchase it from?

I have never seen that cable before. This pic shows the only Uniden OEM Hardwire kit I know of.

Looks as though it may be made for a motorcycle for audible alerts specifically.

do you think those wires are safe to connect straight to the battery?

I'd hate to lead you in the wrong direction especially since I've never seen that type of cable before. I suggest contacting the folks that sold it to you. Too expensive a RD to take any chances.

The fuse rating should be much lower to protect the RD. (2 AMP)
Contact the vendor that sold it to you before splicing into anything.

If you have a cigarette lighter plug, why don't you just use the cigarette lighter power cord that came with the detector?

That's not how it works. Current is DRAWN not delivered. The fuse is intended to protect the wiring from a faulty device in case a malfunction or short causes more current than it's capable of handling to be drawn. It's to stop the fire.

You could, and that's how I would do it as long as you don't plan to exceed 10 amps with the detector and the lighter simultaneously. The "right" way to do it would be to wire a relay from the batter with an inline fuse trigger by an accessory circuit that's on with the key.

It should be fused either way IMO.

Does any radar detector draw high enough amperage to require a relay?

Not really, it's more to avoid using the accessory relay to drive anything directly on a motorcycle. Depends on the specific bike, but it could vary.

I hear ya. I'm curious to know more about that cable. Looks like a 3.5mm for an external speaker.

I'm assuming it's for a motorcycle headset input. Kinda hard to hear your RD go off when your blasting down the back roads at 100+ on a bike lol.
