Using the pcm controlled shift light

[Chris81]

Ok, i'm not the greatest with electrical stuff, could someone help me with instructions on how to setup a shift light in my 2002 Z06?

I found a couple of threads on this, but i'm a little confused on what exactly to do as far as the wiring using the pcm pins and building a light (i'd like to do my own LEDs)

Any help would be greatly appreciated.

LED's don't work too well, you need to use real globes. The LED's will stay lit (dim) when not on.
If using a globe one side needs to go to +12V Ign, the other side to the PCM pin, but sorry, I don't recall the pin number.
FYI, on the Holden HSV they had a shift light from factory, they always false triggered, it's not the best system to use for a real shift light.

LEDs are pretty much fine - I've got some (6) ultra-bright yellow LEDs ... I hooked them up for starters to see how "bad" the glow during off-time is ... it's not too bad ... anyway, if it's too much for you, you can always add a bit of electronics to control the light with a transistor ...
Anyway, I got mine in the air duct of the center console ... nice and mostly invisible ... ;) if I don't want to see it at night, I can just close the vents ;)
Oh, and I've not had any problems with "wrong" triggering - they've not come on too early or outside the shift range, and according to my quartermile logs, it came on at the right time ;)

Nice one, I just remember riding in Paul's (ex) HSV GTS which had a shiftlight fitted from factory, it used to come on (with an annoying beep) when taking off from a stand still every now and then :shock:

My GTO has the shift light built in, but disabled from GM. Any idea how to enable it?
