I have an automatic and I'm trying to turn off this shift light.

In the constants
Shift Light Output- I raised all the way up
Shift Light RPM (8 cyl) , I've raised to 9999 RPM

Under option words

Option word 3 bit 4, I've even checked and unchecked


the darn thing still doesn't turn off, stays on all the time. Is there another area to turn this off?
thanks

 

Are you sure that the shift light is controlled by the ECM? The reason I ask is that looking at an '84 Y body ECM pin out ('6026), none are for a shift light.

Pull the bulb out. If there is a bulb in there, in an automatic trans car, it will come on & stay on (I know because I tried this). Just pull the bulb. Pretty simple.

 

Not in a digital dash its not that simple. (corvette)

Well I don't know for sure how its wired into the ecm or if that controls it. The only thing I can go off of is that when the car was a TBI and I first put ebl in the light was on. Went into the program and was able to turn it off. Went to muultiport and All of a sudden its shown up again and won't go off. May have to live with it.

 

Well, I've literally gone through every LCD dash schmatic from years 84 to 86 and now where's can I find a wire that supplies a signal to the shift light. So looks like I better get used to it.

 

If you feel like emailing/PM me a link to the diagrams (or the diagrams themselves), I'll take a look at it.
