I got the Direct Connect 2 inch Trailer Hitch Mount Model 1601B. I installed the wiring when I did the camera so it was real easy to bring it in thru the back. If you want to do it this way follow the instructions for the camera install. Otherwise you'd have to run it under the body and come in thru the engine firewall.
The hitch mount was not a good fit as the spacing was off for their connectors into the Honda hitch reciever. Easily fixed by drilling new holes closer to the front on the sides which did not have any holes in them and I drilled closer to the front by 1 diameter of the existing holes, had to use the other side otherwise I would have ended up with a slot since the edge of the new hole would touch the older one. The piece I'm talking about is just the plastic piece that slides into the trailer hitch, really easy.
Then you have to tap into the reverse light wires for power. The reverse light green wire is hot and splices to the red wire. The orange wire is ground and splices to the black wire. Use a tap splice or solder directly which is what I did.
Not much else to it except running the wires.
Difference between radar & ultrasonic sonic sensors (like Honda offers). The radar system is not effected by wind, rain, dirt, works in all conditions unlike the ultrasonics. The radar also only detects moving objects so it won't go off unless you are moving or the object is moving towards you. This unit goes into full warning (constant audio tone) when you are 3 feet from an object. So then, the radar system isn't good if you are using it as a parking aid trying to squeeze out the last inch parallel parking. I don't know the minimum distance for the ultrasonics but they'd be better suited in this situation as a parking assistant. Read their promo material for more details on the differences.
I also have the rear camera so these two systems really work well together. I don't backup watching the camera screen, I only check it before I start out. If my radar sensor goes off then I'll stop and check the camera screen to see what's behind me. It's a great system and I have full confindence now when backing out I'll never hit anything unexpected. Specially since I live on the end of a culdesac and the there's about 12 kids always in the court playing games of sorts.
PS. the pic is a little deceiving making it look like it sticks out kinda far, it really only sticks out past the bumper by no more than an inch. |
Thanks vertrkr for the advice on the wireless sensors on the other thread.

I checked out the site for the doppler radar kind. Sounds like a better system. Any shortcomings crop up yet?
I also looked at the install instructions for the backup camera as you suggested above. I still have a problem about dismantling half the truck to run the wires into the cab.
I had an idea about running the wires inside the bed, along the underside of the RETRAX rails (ordering the cover soon) and mounting the Notification Display unit onto the bottom of the RETRAX cover canister near to the rear-sliding window.
Can you tell me how loud the warning buzzer is? Do you think I'd be able to hear it from inside the cab with or without opening the rear window?
