Good price and quality. Wires are only about four inches so installing the bypass switch for amp (or other need) may be a bit challenging as you will have to cut and splice that in. I would recommend this for making the RR and KT150 install go smoother. I've had my dash apart so many times I am now an expert! I tried the other M brand and this will not work with a 5846b just the KT150 for which it was designed. Plug (power) in I need for the RR on the F150 is occupied by the 5846. Shame I really like the display setup for HVAC controls on the 5846. Here's to hoping the KT150 performs well. Review: Works as expected - Quality cable that works ## Features - The iDatalink Maestro ACC-HU-PIO1 adapter allows you to connect select PIONEER radios to compatible iDatalink T-harnesses. This extra harness takes the place of the harness that comes with your new PIONEER stereo. It connects directly between select PIONEER radios and the latest Maestro "Head-unit ready" T-harnesses so you won't have to splice any wires. - Connects in between Idatalink Maestro vehicle-specific T-harness and select PIONEER head units - Also requires an iDatalink Maestro ADS-MRR, ADS-MRR2 or ADS-SR module and compatible iDatalink vehicle-specific T-harness - Note: This harness will not work by itself.

The ADS-MRR or ADS-MRR2 will require the "HRN-HRR" series T-harness for . (It MUST be the Head Unit Ready "HRN-HRR" version, NOT the HRN-RR one.) The ADS-MSR will require the "HRN-SR" Series T-harness.
