C5 Corvette Zex install Who can help me figure out how to wire the white throttle position wire from a zex wet unit to the throttle position sensor on a C5 corvette (2001)?
It is a fly-by-wire throttle system.
It is a fly-by-wire throttle system.
It doesn't say in the directions...or did you get the kit used?
On a C5, I'm 90% sure, it is the purple wire. It has been a little while since I've done an install.
To find the proper wire from the TPS: use a voltmeter, with car ignition on, stab
the positive lead of the voltmeter into each wire while opening and closing the throttle. The correct wire will show a change in voltage as you open/close the throttle.
FOR OTHER D.B.W. users (drive by wire): for a C6 tap into the purple TPS wire at the lower rear of the plug ( i have seen 1 person say green wire here too...possibly 2 signals on the vette ). On a GTO it is the green wire at the top rear of the plug. ON a GTO, there is actually 2 TPS signals - one rising and one falling voltage. The green wire is the falling voltage signal and can be used.

Thanks, Zex said TPS is at peday Zex tech informed me that the TPS is at the gas pedal. Is that true or is it at the throttle body. The C5 has a drive by wire system, the LS1 camaros use a cable system. Thanks for all your help!
There are wires that go near the fuel injection, along the rails, to the Throttle Body. Yes, there are NO cables, a C5 is DBW...but it does still need wires and those wires pass along the aforementioned area and go to the T.B.

zex kit TPS wire The zex tech told me the signal would not be accurate at the throttle body and needed to be tapped into at the gas pedal. It sounded strange to me and I was planning on calling again to try to speak with someone else. I don't know how to move this to the nitrous section.
Right click up in your browser address bar, copy and paste the link to this post into a new post in the nitrous section. I would do it for you but I have to leave to be at a customers.
I've done several installs on a C5 using the wire near the fuel injectors...without issues.
