530t

The 552T has a negative when armed output. It is the Orange wire on H1, this would be the wire that goes to the Orange on the 530T. There is a RED / white channel 2 output from the 552T that normally controls a trunk release, you can use that to the RED / white on the 530T to roll down. The window wires you need to interface are in each door. LF Window up/dn      blue - brown       type A       driver door switch RF Window up/dn     blue - brown       type A       passenger door switch Hope this helps. Keep us posted.

if you thought the blue wire was a ground when armed ou should take it to a professional.
