GoTexas

Over the weekend, I hardwired my radar, and it powers on as expected. The problem is when I turn off the ignition, and even after arming the car, there is still power going to the radar. So, I am forced to having to remember to manually turn it off. Does anyone know how I can get it to turn off with the ignition?



I am using the open slot (B7), but I have also tried to piggy back off the B6, and B9 with the same result.

GoTexas, Question from a Longhorn dad....what bracket are you using to mount to the mirror? Sorry I can't help with your question on fuse connection.

GoTexas

Ok, since you're not an ATM dad, I will answer your question It's the super cup windshield mount from ebay.

In my 997.2 , fuse slot C1 is switched. However, I don't know which slots are switched in the 991.

I was just wondering if you turn on the radar detector, after the car has been sitting for a while and before you turn on the ignition, if the detector turns on?? The reason I ask is that in newer cars some switched systems do not turn off immediately when the ignition is switched off but rather 20 to 30 minutes later when the car goes to “sleep”. Ran into this on a BMW.

I only want to use the 10A slots, so I am restricted to those 2 in the pic. But, neither one of those two are switched...perhaps one of the other ones are.

I have not waited that long, but I'll do that tonight. I have only waited 5 minutes before, but was wondering the same thing you are.

which fuse box did u use? I hardwired my val 1 into the passenger footwell one. Had to try a bunch of different slots but eventually I did find one that was switched off with ignition. Most power off around 30 minutes later which I did not want to do. I am not sure off hand of the exact fuse but I believe it was the one for the passenger side ventilated seat.

GoTexas

Thanks for the response. I did consider the passenger fuse box, but because it houses the air bags fuses, so I didn't want to mess with it. Also, now that I already have run down on the driver side, I am too lazy to switch it. I'll test it tonight, and if it goes out in 30 mins then I can live with it.

I hard wired mine to the passenger well fuse box. On the bottom row there are several that go on and off with the ignition. I think I used the 3rd one in from the fire wall.

GoTexas

no luck. tried all of the unused slots on the passenger fusebox, but they're not switched enabled. There was no other 10A slot, and I didn't want to piggy off of any non-10A. Also, the radar stayed on for 1hr plus instead turning off after 20-30 mins like some had thought. Maybe the 991 is different from the other models. oh well, it is what it is.

I am not sure you should worry about using a higher amp circuit. Just put in a 10 amp inline fuse. I just wouldn’t attach the radar circuit in with a safety related circuit (airbags, ABS, etc.).

I wire all of mine to the rear wiper, it's a switched fuse that tuns on and off with the car. However, if you use that feature to save gas your radar will turn off and back on at lights. I have that feature shut off and it works great. I do it in all my 911s. Rear wiper fuse is the ticket.

GoTexas

Oh that's good to know. Mine doesn't have the rear wiper, so that slot should be open. I also turn off that gas saving feature, so it won't matter to me either. Thanks Scott. I will give it a try this weekend.

I will be doing the same install this weekend, any problem getting the wire up to the mirror/radar unit? Is the window post molding just a 'pull off'?
I also read that if you did not get the smoking package that there might be an unused power source in the center console that was meant for the cigarette lighter. was thinking of getting my power there....any thoughts?

Yes, a few thoughts:
- running the wire is easy, just don't use a sharp tool that could do damage when you tuck the wire in!
- use a meter and find an available switched circuit, there are plenty on both sides!
- be gentle removing the carpeted fuse box cover, if you don't slide it rearwards you will break the flimsy guide tab (ask me how I know )
- the factory bracket and suction cups allow you to tuck it above the mirror, Maybe not an elegant solution, but cheap and effective.
- Oh, and Escort's newer 8500 for $300 is all the radar detector anyone needs! Trade-in your old one and get it for $220! (don't pay extra for the bogus "blue" plastic lens either)
