I've mounted my digi dash in the centre of my steering wheel to prevent clutering the dash too much, but now I'm faced with the dilema of how to wire it in without it tangling everytime you turn the wheel.....anybody got any solutions??? Think its about 8 wires in total and its a Sierra steering column. Cheers Oli.

demon thieves do a quick release with a connector in the middles,

Linky thing

not cheap at nearly £300 quid though!!

Curly Umbilical cord? Radio transmitter/ receiver?

Sprimngy umbilical cord is waht you want. Old(ish) style phone kind of thing.

One of these chopped in half and run as a pair

or chop up a few old phones.

i would go for the

copper idea!

its just a brushsystem!
and it will give the best result...

i would built it in the steering wheel.. (swap it with the original sierra one..)

Tks

mmmm, had thought of both of these solutions....think I'll have to go with umbillical style cord but how to stop it dangling but at the same time catching on everything! Cheers Oli.

Brushes and slip rings are a bad idea, they cause electrical noise when moving and will quickly wear around the straight ahead position. They are simply not a very reliable method of transfering low level signals.

Car manufacturers knew this a long time ago, and to solve this problem they use whats known as a "clock spring" on modern cars with steering wheel controls and airbags. This is simply a long strip of a kind of flexible PCB with tracks etched into it, wound into a coil. The coil is pre-set on assembly so that it doesn't run out of length over the whole steering lock. Grabbing one of these from a suitable scrapper would solve your problems.

Interesting but where the hell do you find it (eg. car? model? year?) and how would you make it work in a sierra column....Oli.
