Becker satnav requests speedo and reverse signal

Hi ,

I just bought myself a becker 7820 satnav system. the wireing diagram request a connection to my speedo signal and my reverse swith or reverse light has anyone any clue where i can best pick up those two wires ? and the collor codes of these or other regonisable items ?

hope someone can help me soon so i can get it working before i take it on my skying trip.

The speedo feed can be taken from one of the outputs from the ECU, sure someone here knows but I cannot remember. Someone will be along to tell you which wire.

For the reverse light you will need to take a feed form the reverse switch which is housed (IIRC) in the gearbox casing.

Getting both sorted should not be too difficult.

i need to find the speed sensor for my turbo timer (which i've had for about 15 months and still haven't fitted)

This should help, see page 20. Speed sensor is pin 9.

but how would you get from pin 9 to the acctual wire? the first time you see the wires, it's in a big bunch, all twisted round each other. the plug onto the ecu is a plastic seaed unit i don't fancy breaking! cheers anyway mate!

Craig, its the white cable you need.

See here about half way down.

Thanks for the info guys,

Unit is in there and works fine put the speedo wire into the iso connector of the ecu for now , didn't want to splice into the cable

a small note to the drawing on page 20 of the workplace manual, the pinout of the connector does not corrospond with the actual thing, the ecu looks correct

so think it's down to that I have a LHD car and the ECU is on the other side of the car.
