VERY cool parking assist mod

I think your setup needs more wind tunnel testing.

 

Sweet, Just came across this post. I want on my prius!

 

I noticed the entire exposed part of your sensor is silver. Did you paint the whole thing or did you mask off the metal sensor and only paint the plastic?

 

I WOULD BE "IN" for a group purchase !!! front and rear !!! Thanks

 

thread is a year old dude.

 

I finally had the execuse to get back to this project. I bought an audio-alert only backup sensor package versus one with video. I could've cobbled together from various threads the information to overlay a differnt package's video over the Toyota OEM NAV system, but didn't want that much trouble. But there are now sensor packages on ebay where the control box in the back is wireless with respect to the display unit in the front. This makes it easy to handle the back-end install separately (i.e. different weekends) from the dash-install. I also followed your advice and bought a nylon-pry tool set on eBay.

The most useful tool was a small one to help pull the center pin on the plugs. With the plugs and screws removed, since the bumper cover essentially rotates bottom-to-top (counter-clockwise), the other attachments at the sides just popped off, no prying required. It also makes sense to remove the underside corner wheel well trim pieces first since they hold-down the center trim piece. The corner pieces are also where those extra clips were you mentioned. And a final note was that the right corner trim piece used a plastic nut that initially left me puzzled.

I also used your prior advice and used a heat-gun to pop out the deformaties in the bumper cover. That worked very well.

But the most useful discovery I made in the process was, after already taking the time to measure a bunch of times the locations for the sensors per my packages' instructions, that my inside bumper cover was already embossed with four circled-X's marking the locations of the Toyota sensors. Their measured locations matched the TPA manual linked-to above. And not only did I find that their locations were within the placement tolerances of my packages' sensors, but they made sense in that their locations avoided the actual bumper and styrofoam cover. So I abandoned my measured locations and went with Toyota's. Knowing not to fret over the vertical and horizontal measurements and leveling would've saved me at least a half hour.

In the TPA manual, on Page. 20, Fig. 25, there's a connector which is labeled L6. It looks like the Z cable effects an in-line splice to power the Toyota unit, i.e. L6 & Z9 are the same connector with whatever is the Reverse signal siphoned off. Does anyone have access to a pin-out of L6?

I'll post again when I find the reverse-tail-light wire and get the thing wired up.
