I assume you are using a stock style tilt column, something like 70's-80's mopar or GM???

basically here is what most columns have, there is a ING switch set up and then a 7-8 wire plug for the turn/brake lights(horn to)

so you will have 3 feeds in to that plug(usually pink,red and white)

1 comes in fron your stop light switch(white wire)
1 comes in from the turn signal flasher
1 comes in from the 4 way flasher

then you have 4 coming out
1 right front turn
1 left front turn
1 right rear turn and stop
1 left rear turn and stop

you need to hook up the turn indicators on the dash to the RF and LF wires or when you hit the brakes the dash light will come on(been there done that)


Oh and the last wire in that plug should be to the horn relay(you also might have a light wire for the key area)
depends on what column you have.

it sounds like the rear and front wires are hooked up together and are feeding the front turn lights with the feed that should go to the rear only. hope this helps. Ron...

let us know how it works out...
