At the risk of sounding dumb, I have a question... The upshift light on my 87 GLHS isn't working. The car has the MP computer in it but is otherwise stock. I know it can be annoying having it come on all the time, but I'd like it to work. Is there something that people commonly did to disable them? I had an 86 SC back in the early late 80's and seem to remember it having the light, but maybe I'm making stuff up in my old age...
Welcome to the site. I don't believe the shift light worked in the turbo cars from the factory.
Thanks for the fast answer, and the Welcome.
Cordes is right as always. Just shift when it's tongue starts to hang out (lol). :p Shift lights and boost gauges were both MIA on turbo L-bodies.
Good to know, I'm still trying to figure out how in the world I knew that was a shift light in the first place. It's been 25 years since I sold my 86, and if that one didn't have the light I honestly have no idea how I'd have known it was there. :thumb: thanks again for the quick answers and good info.
shift light ??
I know the power loss lamp lights up when you get to the limiter .. BUT , I wouldn't call that a shift light ..though I do have a spot where it is a shift lamp ..at the top of third
same spot every time .. lamp STARTS to glow .. I shift , lamp never actually gets to full brightness..
I maybe wrong but didn't some of the early miserly L bodies come with an up-shift light for mileage purposes?

I'm pretty sure that's what the OP is talking about.Quote:

in an L body the vacuum diaphragm on top of the spark control computer ..(looks like PM) is what makes the pacer lamp work
and.. they never put them in a turbo car - they only get the plastic block off plate where the fuel pacer diagram would fit
it was never anything more than one of those vacuum operated fuel mileage gauges .. without the poor/fair/good/excellent "gauge"
Yeah, I'm guessing that it was an upshift light for fuel mileage, and not a shift light. I just didn't know what to call it. I'm glad that it isn't supposed to work, so I don't have to chase down a problem! Thanks for the help!
My 1981 Omni Mizer with the 1.7L had the shift light, and my 1987 Horizon with the 2.2L and 5 speed may have had it, both had the feedback carbs and spark computers. I would imagine the full gauge clusters all had the provision as Chrysler wasn't into different clusters for anything other than base or full gauges. The 87 FSM shows just one printed circuit board for full gauges.
I'm pretty sure the electronics for the F P light are all inside the spark control computer .. as I converted my 85 turismo ..2.2 carb 5spd to log turbo and I lost the fuel pacer function as soon as the engine harness and PM/LM got swapped in with the still same dash harness & full gauge cluster
it's "just" a vacuum triggered light bulb .. it probably wouldn't be hard to separate or find something else ..
like a cheep asian shift lamp..
I believe the wiring is there in the turbo l-bodies for the fuel pacer light. At least from the LM to gauge cluster. Orange with light green tracer sort of rings a bell in LM red #4. I seem to remember having to remove that wiring terminal when converting from 85 to 87 logic module. Red #4 terminal then gets used as power loss light on 87 wiring. The crazy crap you remember when doing something repeatedly...;)Quote:

I thought that's what that wire was for too. It's the one you can just leave out if I'm not mistaken.Quote:
