Hypertek Posted February 27, 2015 Share Posted February 27, 2015 Hey guys, I am following this post on the zx distributor upgrade to my early 260z http://forums.hybridz.org/topic/104933-1974-260z-with-e12-80-280zx-distributor-swap-wiring-with-tach-hook-up/ Was just a bit confused, do I need to add a constant positive feed from my battery to the coil? Or should it be from an ignition on switch and where could a source be located? I have no problem adding a positive wire from my battery to the coil, but just wasn't sure if his diagram was correct. Thanks Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 27, 2015 Share Posted February 27, 2015 There's some bad information in that thread. I stopped reading when I saw the thing about the aquarium valve on the vacuum advance hose. Kind of ingenious but the analysis of how the mechanism operates was incomplete. Here's a site with some ideas that seems to work well. You want power when the key is On, and at Start. Pretty sure if you wired it the way it's shown in that thread, the engine would not turn off with the key. It's basically "hotwired": http://atlanticz.ca/zclub/techtips/distributor/index.html Quote Link to comment Share on other sites More sharing options...
Hypertek Posted February 27, 2015 Author Share Posted February 27, 2015 So i just need to find a switched ignition source to power it up right? Who else has done this to a 260? If someone can point me to where to tap from. Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 27, 2015 Share Posted February 27, 2015 (edited) Nothing special about a 260. Open the link and read. You've already been pointed. The wires are already there, at the ballast resistor. Edited February 27, 2015 by NewZed Quote Link to comment Share on other sites More sharing options...
88dangerdan Posted February 27, 2015 Share Posted February 27, 2015 this is the way I have my early 260z wired Quote Link to comment Share on other sites More sharing options...
NewZed Posted February 27, 2015 Share Posted February 27, 2015 Is it really wired that way or you just think it is? You show constant power to the coil and ignition module, even with the key off. Makes no sense. Just use the factory wires at the ballast. Nice use of color in the drawing though, I can see why it's attractive. Quote Link to comment Share on other sites More sharing options...
88dangerdan Posted February 28, 2015 Share Posted February 28, 2015 Yes I did just use the wires from the harness. I just interpreted the red line as positive power source not actual wire connection. Just have two wires on the positive and two wires on the negative attached to the coil Quote Link to comment Share on other sites More sharing options...
