Pioneer DEH-X7500SHarness/Scosche FD16B Harness

[It's Me 0]

Hello

 

 

Im knew to the forum and a newbie and need some help.

 

 

I got all wires connected besides 3 on the Scosche harness(orange with black line saying dimmer ground)(black with silver line saying amplifier grond)(all black saying chassis ground)

 

 

2 on the Pioneer harness(blue with a white line silver spots with a tag saying system remote control)(black with silver spots,seems to be twice as long as the others)

 

 

Do I twist all 3 wires from the Scosche harness to gether and hook it to the 1 long black with silver spots wire from the Pioneer harness?

 

Is the blue wire with a white line silver spots with a tag saying system remote control for external amp,where it says remote in between pow/grd?

 

 

Thanks for the help.
