530T Window Automation System

The 530T window automation system controls the operation of two vehicle windows in both the up and down

directions. The 530T automatically rolls up the power windows when the security system is armed, as well as pro-

viding “one-touch” operation in either direction. The 530T can also be used to vent or roll the windows

completely down with an auxiliary channel from the security system.

Before wiring the 530T, it is important to understand how different window systems work. A 12VDC motor must

have (+)12V on one of its wires and (-) chassis ground on the other in order for it to operate. Most window

switches are connected directly to the window motor with two wires. These two wires will either rest at (-)

ground, (+)12V ignition, or sometimes they will rest open. In any of these systems, the switch, when activated,

will send (+)12V to one wire and (-) ground to the other wire. Which wire gets (+)12V and which wire gets (-)

ground determines which direction the motor will roll the window.

The three window systems will be referred to in this manual as type A, B, or C. To determine which type of system

you have, turn the ignition on, check the power window wires at the switch with a meter to see what polarity

they rest at. If they rest at (-) ground, you have a type A system. This is the most common system. If they rest

at 12V when the ignition is on, you have a type B system. This system is used on many European vehicles. If the

wires rest open, you have a type C system. The wiring for the type A and type C systems is exactly the same,

however, the type B system differs slightly.

NOTE: If the vehicle is equipped with any type of factory automatic full-travel or “one-touch”

system on the driver’s window, there may be a relay or module in the driver’s door. Be sure to inter-

face with the wires between the module and the window motor.
