DIY tools and adaptors.

The owner had lost all keys, so he wanted a immo off for the car.

Meaty: I don?t have any interests to hijack the Webasto thread. I know enough about the subject.

It?s been a lot of work to solve the problems with the controllers. All I try to give is the basics to start with.

Forgot to look at the port settings, but there?s always next week.

That adapter looks pretty good do you have the layout of the wires of what goes where and how 12v and ignition are wired up??Also what do you use as a 12v power source for clusters and ecus??and how is it connected to the obd connector

Power goes in to the obd connector from the same connector row as they leave.

+12V goes to obd pin 16
GND goes to obd pins 4 and 5
K-line goes to obd pin 7
Ignition is connected to +12V and has a switch
Relay out is connected to +12V when relay is active
Relay control goes to an ecu etc. wich grounds the relay. The other end of relay coil is connected to +12V

CAN H and L you can find out yourself.

This is really simple that you can imagine this schematic in your head and don?t need any drawings.

Oh and here is the port settings used in USB k-line adapter for webasto controllers and ThermoTest sw.
