Being new to the forum I thought I should contribte something, and it only took one hard glare from a policeman on the way home from the dealer to convince me I should install my radar detector ASAP.

I apologize for the lack of pictures, but this should be used as a guide only anyway. Use at your own risk, blah, blah :roll:

Here goes:

1) All detectors I am aware of are in need of a good 12V line to wire into. I installed an Escort 8500 with a direct wiring kit, but this should apply to all brands/models.

2) I used the power lines to my auto mirror/compass, becuase they turn off with the ignition. If you don't have one you can go straight to the map light lines, but will have to turn your detector off manually.

3) Pop the map light lense cover off and undo the two phillips screws holding the unit in. It should drop right down.

4) Identify the compass wiring harness plug (wrapped in foam to the right)
and unplug it. Verify you got the right one by turning the ignition key to ACC and see if your mirror fails to turn on now.

5) There are three wires coming from your mirror, blue, black and green I think. You want 12V + and ground, and I found this to be the blue wire (hot) and the black wire (ground). YOU SHOULD VERIFY THIS WITH A MULTIMETER! If there is one thing that the internet is good for it is telling you to cut the wrong wire! :eek:

6) Once you are happy you have the right ones, strip a small section of insulation off and solder in your detecotr leads. (On an Escort 8500 the red/black with fuse lead goes to hot and the black is ground.) I am not going into the deals as how to best do this. If you are comfortable taking a soldering iron to your new car you better already know.

7) Strain relief the solder joints somehow, bundle any excess wire and stuff it in there anyway you want. Instead of cutting a hole in my headliner for the wire to come out, I found it was cleaner to just run out the front of the headliner where it meets the winshield.

Hope this was useful. Now I just need a better way to bolt up the dector unit itself....

Thanks. I was thinking about this last night as I just ordered a BEL 985. I actually didn't ask for the auto/compass mirror, but it was on the only car with blue/gold and I didn't pay any extra for it. I was going to use the map lights but your method sounds good.

Stupid question, wonder if the additional current draw on the mirror power will create any problems? I may be blind, but I didn't see on Beltronics web site what kind of current it pulls. I'm sure it's a few milliamps but I am curious.

Thanks again for the tip.

Great idea! Do you know if this is pre-wired even if you don't have the auto mirror installed?

Thanks,

It should be easy enough check and see if the car is pre-wired for the compass. Just pull the map light console down and look for the unused harness. (Verify with a multimeter.) My guess is that it probably is there already.

As for current draw, I don't think this will be a problem. I have spliced off of 12V power lines for more sensitive electronics in other cars and never had a problem. I would be more worried about the detector getting spiked(>$$) so I put a 5A fuse in line when wiring it up.

Sorry to keep asking questions, but what type of fuse did you use? I'm assuming a standard "cylinder" shape fuse. Just wondering how much extra junk will fit in the map light cover.

Thanks again. Good idea about the fuse. I wired one to a map light before but didn't think to include one.

yea stock tires

Just a standard 5A "cylinder" fuse as you put it. You can buy a fuse holder from any electronics store and wire it inline. There is plenty of space in the headliner around the map light dome so no worries on fit.

Awesome. Thanks for posting your tip, very nice. Would be cool if we could have an "electronics" section added to the FAQ and this article be entered there.

Maybe you could get it added to the "Misc" or "interior" section?

i've already posted on this, but somebody did a really pro looking site about hardwiring a v1 in a wrx. i did the same thing w/ mine,and it works great. all cars will have the wiring for the auto-dimming mirror, and there is plenty of room up there to stuff the bits that come w/ the wiring kit. most manufacturers include a fuse in their kit.

Cool. Thanks, Tim.

Something I just thought of - I assume cutting into the power for the mirror means the compass has to be re-calibrated.

I hardwired my V1 using the auto dimming mirror power line (I believe it was brown/yellow) and then just reconnected everything. Initially the compass function was blank but after a few minutes of driving it works as well as ever. I know for some GPS units all that's required to re-calibrate is a few spins on a level surface....maybe the STi's compass works on a similiar principle? In any event I know when I'm heading South it reads S, N when going North, etc.

Nice job, TRM. Good job on the article and the pictures... I think I prefer the mirror/maplight method though... much simpler and much less running of wires. :D

My voltages on the mirror power seem wrong. On blue/black, I got ~ 15.5V. On black/green, nothing. Is that right?

Does anyone know if my voltages were correct? First off, I expected 12V, not 15, and secondly, I expected something on green as well.

Secondly I blew the 20A fuse mentioned in the valentine one instructions above... :lol:

PS. I have a BEL 985 and I'm not sure on the straight power cord whether the black or the white is supposed to be my ground. Any thoughts on that? Thanks! Never seen black not be ground but who knows.

Okay, I got it working. Obviously the black/white on the adapter for the Bel was the power, black only was ground.

For my inline fuse, I used the fuse that was included in the adapter's "cigarette lighter" tip and put it in a fuse holder inline with the power. Works great. Even have a spare that I taped to the inside of my coin box.

Also, a tip for those who, like me, can be clumsy sometimes - spread a towel over the center console, especially the parking brake. I dropped one of the maplight cover screws into it and it took me almost 40 minutes of searching with a flashlight before I saw it in there. I did not have my handy extendable magnet tool that I have at work, so I used a long screwdriver with some sticky tape wadded on the end and managed to retrieve it that way.

I always seem to like making stuff hard for myself. :roll:

Anyway, works great, thanks for the tips from all those who wrote up their procedures.

First off where are you grounding your meter to check for voltages on the wires?

Second, most often black is ground and white is hot. So you're probably right there.

I was testing the blue/black lines of the mirror circuit and getting 15.5 V as I indicated. I assumed the black is the ground for the mirror circuit.

Nevertheless, it doesn't matter, because after reading the manual some more, I realized that anything between 10.5 - 15.5 V is in the acceptable range. It works at any rate, and the mirror still works fine, so it's fine by me.

installed my Alpine 9807 & Infinity Reference Speakers

Looks good. (Or at least just like mine. :wink: )

I think eventaully I will make or have made a bracket to bolt the dector into the centor visor scew holes instead of using the suction cups.
