Does anyone have a Barcelona Red TCH with backup sensors (aka Park Pilot)? If so, were you able to find the sensors pre-painted or did you have to have them painted locally? Do you have 2 sensor or 4 sensor system?

I'd like to have backup sensors installed on my TCH, but have been unable to find any pre-painted Barcelona Red sensors. I also don't know whether I should be looking for a 2 sensor or 4 sensor system. Are backup sensors typically installed by a body shop or by a car stereo/alarm shop? (I'm looking for an installer in the Raleigh, NC area.)

Any recommendations would be appreciated. Thanks in advance...
