LT77: power (+) for reverse light & speed transducer

[RochdaleGT]

does the reverse light switch and the speed transducer share the same +feed ?

my reverse-light isnt working, engine isnt running as smooth as expected and its only 2 moths a go where a new speed transducer was installed (from the former car-owner). i think he also tried to cure the un-smooth running, but wothout success.

if both functions share the same plus-feed a new trasnducer might not cure any problems when he isnt connected anywhere to plus.

forgot to say: the speedo is working correctly.

Yes if the brake and reverse lights work you have power to the sender on the same feed.

brakes work, reverse not....where the live-feed for reverse and transducer are split? neat the box or near the fuse-board?

On my 97 the reverse is from fuse 8, brakes are from fuse 18, speed sender does not have a live feed it is a connection (grey wire) from the speed module, the other side of the sender is a black wire to earth.
