Your clusters not broken, the shift up light is in all the consoles but only functions with the iron duke ECU.

anyway to make it work on GT's? im sure my brother would like his to work.

Not to my knowledge, the 4cyl ecu knows the optimal shift points for the stock Iron duke, the SE/formula/GT ecu does not. I don't think the V6 has the output on the harness for that wire. If I am wrong please let me know, I'd like for mine to work but I don't think its possible. However for like $60 one of those guage companies makes a pen sized shift light thats universal, so I guess you could wire it up inside the dash, cut up the housing, and stick the bulb in the slot.

now that one sounds like a perfect solution.

Well my 86SE with the stock 2.8 must have been broke, cause the shift light worked in it. it was very annoying

Both of my manual cars have up shift lights. There are 2 shift points,,, one for gas milage and one for power. Both of my cars are V6s. The 85 is an SE2M6 the 86 is a GT.

My old 86 se had a working one also, that car had 172K on the odo. I remember driving down I-95 at wot and had the needle pegged and the light was steady, weird.

NOT true... I have an 85 GT mine has an upshift light and it works! They also did in the other 2 85 V6s i owned.

Well there was another thread dedicated to it and the 87-88 GTs never worked, thats just what fellow members have told me. Mine in 19 years never worked. Some guy from the car show with an 88 Formulas never came on.

I would just check to see whether a wire has come off in the engine bay. I have had to fix most of my guages due to the brittle solder joins and wires.

I have an 88 no one else who has an 88 I have ever talked to has one that has kicked on in 19 years.

I believe that 86 was the last year that the shift light was stock from the factory. The light worked on 85 and 86 year models.

wow. 86 was the last year? that makes me want to figure out how to get it to work on the 87 n 88's. my brother has a 87. and he is decking his 3.4 out. im sure he would love that light for the milage.

The upshift light in my 85 GT works...and my 87 GT doesn't. I was wondering the same thing, always thought something got disconnected somewhere.

Mine did to, until I took out the light. Annoying little bugger

id just wire a push on/off switch to it to have it on when u want to really optimize your mpg. off when you are emptying your tank at the track.

EDIT: corrected my mispellings. im online while on a road trip. bumpy bump. dont worry, im not driving!
