2005 Chrysler Voyager, How To Connect Turn Signals To Central Lock?

Does anyone know how to connect the turn signals to the central lock? I only know from the diagrams that the directions are pins 1-2 (left front, left rear) and 3-4 (right front and right rear) on the C2 BCM plug. The control unit has only one cable output (brown). Do I need to connect diodes? If so, where exactly? Car is Chrysler Voyager IV 2005 3.3V6 and The central lock is Noxon T3

Interesting question. Might be difficult to answer from a U.S. forum. Two reasons: 1. The Sterownik Noxon T3 is not a unit available in the states 2. U.S. vehicles sold overseas can be different due to local regulations. I can't find a detailed install guide for the Noxon T3 but the diagrams I found don't show the output polarity of the Brown Turn Signal wire. I'm guessing that is +12V and possibly fused at 10 Amps. Please check and confirm that assumption. While U.S. market Voyagers have a Parking Light position on the headlight switch, I'm told that Parking Lights aren't a thing in Europe. Here in the states we just connect to the Parking Lights. Not sure if your Voyager has that function or the wiring to support it. You could check to see if either of these two wires are available on your vehicle. Parking Lights   WHITE/BROWN   (+) LOWER DRIVER KICK IN REAR BODY HARNESS Parking Lights Negative   BROWN/WHITE (- 920 OHMS)(-), (MUX)   HEADLIGHT SWITCH OR BCM, CONNECTOR (C5), PIN 31 If you found a White/Brown wire in the drivers side lower kick panel that goes to +12 volts and turns on the turn signal lights, a simple direct connection of the Brown (+) T3 wire would work. In some Voyager/Caravan/Town & Country vehicles that use a MUX wire to control the Parking and Headlights. This wire requires a 920 ohm resistor to chassis ground to actuate the Parking Lights. This would require a relay controlled by the Brown(+) wire. If neither of these is an option going directly to the four turn signal lights would work. First you must verify that the 4 wires you listed at the BCM are (+). If the T3 Brown wire outputs a (+) then you can do a 4 way split on that wire with 1N4001 diodes and connect one leg to each vehicle wire. The diodes band would be towards the vehicle (away from the T3).Soldering is fun!

The central lock has just arrived to me. It turned out that the brown cable was already prepared for the turn signals and was separated at the factory and there are probably diodes installed inside.

No fuse visible but possibly diodes. Still only two wires and you need to make 4 connections. Is the output +12V? Want does the vehicle need as far as polarity on those directional wires at the BCM?Soldering is fun!
