I acquired some Cartek ones but no instructions. I have used the Eclipitec (Shift-i) ones on all of my other cars and they work a treat.. On the VE HSV I had them at the bottom of the screen in my field of view so never missed a change but with the 86 I find that I am hitting the hard limit from time to time and I desperately need some shift lights.
It's usually when someone his hard on your rear bar coming out of a corner which is not a good time to dump a heap of revs on the limiter
Google I guess.. thanks anyway
