Hi everyone, I'm new to the forum and to Turbo Regals in general. I've owned my '87 GN for almost two months now. I was wondering if I could get some of you guy to post some pics of where you have mounted your Tach. I do not want to drill anything. Just wanted to see if there is a clean way of doing it, maybe with a bracket. I saw the one that looks like it goes into the cigarette lighter hole and I don't like that. I have a 2 5/8" Sport-Comp gauge. Also is just tapping into the green plug behind the alternator good enough or does it need a signal amplifier? Thank You
Go to GNS Performance and get the tach bracket. It's a superb piece.
Yes you can just put a 1/4 inch end on your wire and plug it into the green wire behind the alt. It works very well.

X2 on the GNS tach bracket. Here's sort of what it will look, except I made my own tach bracket....this was before GNS came out with theirs.
