Torque Converter Lockup Light

I have read where this can be done by adding a led to the gauge cluster. I would like to know when my TC is locked. Any instructions out there?

99 F250 SD 7.3

I have the manual TC lock up button. To answer your question, You can just follow this rough schematic, Just omit the rest after the green light circuit. The purple/yellow trace can be found in the trans connector.

I put A red led on the gauge pod and on the dash.. To alert me that i have pressed the manual lock up button. So i don't forget.

I put a green led in the dash to show me what the TC is doing.. Green on shows me that the TC is unlocked,, Green off tells me that it is locked up.

Looking at your diagram is it as simple as tapping into the purple/yellow wire and running that wire to one side of the Radio Shack LED light and then grounding the other side of the Led?

Yup.. Tap into the purple/yellow trace. The tap goes to one side of the led and the other side of the light goes to ground.. Then when the TC is Unlocked the light will by on. When Locked the light will go out.

You have a late 99?
