In theory...
It is better used as an "ignore light".

If it bugs you, you can disconnect it from the tach. Its the black wire in the harness connector. Back-probe it with a small, thin tool and you can release the tang that holds the female spade terminal into the harness connector.

Even when you disconnect the black wire, the upshift light will still activate at really high rpms. It's like having a redline shift light you can barely see........... :D

It has a fun aconym, CASIS. Computer Assisted Shift Indicator System.

Or, as I like to say it, Cassie who likes to nag.

Driven97 11-24-2015 11:07 AM

realgren 11-24-2015 11:21 AM

KTL 11-24-2015 11:24 AM

Orange on my former '87 and on my current '86

If it doesn't come on you're shifting too way too early (unless the engine is cold).

DRONE 11-24-2015 07:31 PM

Thanks for the info. I'll have to be a little more agressive with my shift points

Mine was removed by Hollywood Speedo, every time it went on, I felt like I was driving a minivan.

RSBob 11-24-2015 07:55 PM

Dang modern cars. ;)

DRACO A5OG 11-24-2015 08:09 PM

a Pic would really help.

BTW, mine is Orange :D

Turbos don't have one of those since every driver of one already has a shift indicator built into their bodies - heed the clinching of one's personal wastegate! :D

I had mine replaced with something one billion times more useful. Maybe two billion times more useful!

Ding! Ding!! Ding!!!
We have a winner!

Had N. Hollywood Speedo do the same thing to my tach as was done to G85Carrera's tach. Installed a useful voltmeter. One of the best mods that I have done to the 88.

The useful change:
'84 Carrera

Is there a way to disable just the part that lights up for fuel efficiency? I think it's nice as a redline indicator.

I was gonna rig my aftermarket shift light to trigger the stock upshift indicator near redline...
