This is a OEM GM Ultrasonic Rear Park Assist system installed in my car. This system was never offered in a Bonneville OR a Pontiac Car for that matter, that being said there was some modification of the wiring that needed to be done to get the system working correctly

The system uses 4 sensors that are installed in the rear bumper to give the driver warning of objects when driving in reverse. The display is in the headliner, with 3 LED'*. I mounted the Module in the OEM location as the Large GM Cars, Deville, Lucerne, Park Ave Etc.

here are the pics

after lots of planning and measuring



Drilling of the bumper







Sensor trim only


Sensors assembled




Bumper reinstalled





Inside the wiring is easy





Module mounted in the OEM location, the Holes in the body are pre drilled




After your connections are made, time to cut the headliner.

Here is the pattern needed to cut from the donor car


and traced on the Bonneville Headliner

and the Telltale trim bezel installed

questions and comments appreicated

Well done. The bumper looks totally stock. Only a hard core bonneville person would notice. You truly have a one of a kind Bonneville.

how much did that cost Pat? looks nice

wow, that is a really nice install.

Very nice. That would sure help me squeeze in my garage.

you know me Dan, if it dosent look stock, then it dosent get installed on the car.....this goes along with the other OEM installs (RainSense Wipers, Heated Washer Fluid, Heated seat and switch plate, Rear Outboard Heated and Lumbar seats, Rear center console, Turn Signal Mirrors, the projectors from the STS ,and all the GXP stuff.

Well i got all my parts from a 03 Deville in the yard near me, so pricing can vary, but i can tell you the sensors alone new from GM are $230+++ each

Thanks hopefully we can get together so you can see it in person

so finding that in green is going to be well impossible

Very nice I love when parts from other cars fit nice to ours.

Thats why I have GXP seats, an SSEi cluster, and an SSEi exhaust

and thats why i have a GXP interior, GXP Brakes and GXP supension, GXP Tails, GXP spoiler ......along with the other OEM mods...

sorry Frank i had to

And i had to Paint mine,(got them done the same time as my spoiler) they were Orignally Red
