Use this in an 86 GMC truck. Replaced with a retro sound radio with Bluetooth and digital along with hands-free. Harness allowed me to save original factory wires and not cut anything. Super easy to use. Highly recommend.

Ignition, ground , and speaker wires plugged in and worked. The 12v constant and illumination wiring harness (white blade with yellow wire and orange wire) did not fit. I had to use the wiring from the radio. My application is 1986 Chevrolet Silverado

The small plug doesn't fit in the 86 Cadillac DeVille. At less the rest yes, so I'll just create my own constant 12V.
