Hi, I haven't found the info I'm looking for on the towing forums so I thought I'd try here. I'm replacing the connectors on my car (2011 VW Golf) and my trailer. I'm using flat 4 pin connectors, pretty standard, but the trailer had five wires going into the 4 pin connector. I assumed this was just to send a signal to the two different lamps. But when I put a meter on the decapitated plug to see which were the doubled up wires I found 50 ohms across each set of pins. So now I'm confused as to how to proceed. The new plug has infinite resistance between each pin. As I understand it, the modern converters produce a PWM signal to regulate the brightness level for flashing and braking. The converter seemed okay with the original setup (although maybe that's why one channel died?). And I have to assume the resistance was designed to protect the trailer lights somehow. Should I just connect the new plug and risk it? Or can someone explain what's going on?
Thanks, Mike
