5.Z Posted March 18, 2010 Share Posted March 18, 2010 I been wanting to install a voltometer on my early 74 260z (it would have save me getting towed too had I known that my alternator was going.) So I was looking at guages and then I remember the apexi turbo timer I had used before. The thing is pretty small an would serve as cooling down my turbo and shows volt. Anyways I'm curious if anyone else have one? And how did you guys hardwire it? I mean whichwires did you use? I was googling this stuff and found a company that sells one under 240z but his selling a universals kit so I doubt it comes with a plug and play harness Any input?

Lazeum Posted March 18, 2010 Share Posted March 18, 2010 (edited) I had some issues wiring a timer to my previous car (Evo 8) The way to figure it out was with a voltmeter. You just have to check the tension with the ignition lock at several positions. So my advice is to get a voltmeter and connect each wires according to the manual at the correct terminals.

I'm surprise you didn't just buy the plug and play harness. That's how I connected mine in the supra and had zero problems. I have a voltometer already. I guess I will order a tt and just try to hardwire it. If anyone else have any pointers or to watch out for hardwiring one in a Z please post.

I had one but for Evo you have to get the one for DSM. there're 2 versions, the one provided with my TT was the wrong one, so I had to make some mods Quote Link to comment Share on other sites More sharing options...

That was a good read but I was asking about tt/turbo timer not evc. Personally I like my hks evc 3 wich I got for 130 shipped used. Hasn't had any issues with that.

Hugh Posted March 20, 2010 Share Posted March 20, 2010 (edited) Ha, yeah that was a good read. I was waiting for the part where the turbo timer would come in.. but it didn't happen. I tried to hook up my Apexi turbo timer a few years back with no success. I'm actually really good with wiring and electronics, but for some reason this one stumped the heck out of me. I, too, would like the voltmeter to work. In my old 180sx in Japan, I used the O2 sensor display on it as a remote display for my wideband sensor. I programmed my wideband to output between 1 and 2 volts according to air/fuel ratio. 1.00 volts = 10:1, 1.5 volts = 15:1, and so on. Having it right up there in my face without spending any more money on another gauge was nice. Shifting a decimal place over is no problem, too. I don't need a turbo timer for daily use, but it was nice at the track and stuff. I kept it set really short, normally. So I still have the harness adapter from my 180sx and the plugs are the same. The wiring is quite different, however... and I could not for the life of me figure out what each wire in the Z was doing and how to translate it over to the 180sx wiring. I posted this question here a long time ago and received zero response, if I recall. After doing some searching, I'm finding this is a question that is always asked and never answered. Somebody out there must know how to do this properly. Edited March 20, 2010 by Hugh Quote Link to comment Share on other sites More sharing options...
