the small window on the lower right hand side of the dash bezel has four idiot lights( check engine, low fuel,etc.). this is on my 88 saleen which is an lx and the manual says these only work on the gt? i swear that i had an 88 lx that these worked. how do you make them work? harness? bulbs missing? i cant remember. it has been a long time since i have owned a fox body.
