Its a 95 Volvo 850

There is a purple wire that connects to 12v ign from the hfs-1. That powers up the hfs-1. I must not have it connected right but I cannot make heads or tales of the wiring schematics. I used a meter to see if one of the left over ports on the DDS3 box put out 12v when the system was active so it could power the hfs-1 but it didnt. Its the V8 version. Pics attached.
