ignition wiring

[joe newsom]

Hello guys, I am in need of your help. I have searched this site and google for help on this topic ( search not too user friendly for me on this site, must not be doing something right) I have a 71 240z that was an automatic so there is some extra wiring and relay in part of this problem, I am converting to manual. Another problem is that some of the wiring was charred, I took pics and tried not getting things mixed up. The wiring to the coil and distributor does not resemble the FSM, the FSM does not have 2 B/W wires 

from the harness by the driver side horn I have as the following

2 B/W stripe wires- one going to the + on the coil and the other going to the resistor 

1 B wire going to 6 pin plug which goes to timing relay for Automatic Transmission then I believe it is connected to another black wire in that 6 pin plug going to Distributor (not sure where)

1 Y wire that I believe goes the temp sensor

1 G wire going to 6 pin plug for A/T relay then one red wire leaves the plug going the  neg terminal on coil and a wire is spliced going to Distributor (not sure where)

1 G/W stripe going to the other side of the resistor.

any tips or guidance would be very appreciated

Not clear which problem is the problem.  The switch to manual or the wiring.  Does the engine run and the car drive?  Is there something that doesn't work?

And where's the pictures?

Zed I have not started the motor yet. I was just trying to collect info from people that are familiar with the ignition system and try to compare apples to apples. Mine does not match the FSM

Is it a 71 or does it have a 71 build date?  Have you looked at the 72 diagrams?

There aren't many wires.  A multimeter would answer a lot of questions.  The B/W wires are probably the Start and Run power to the coil.  Y is probably the temperature sender.  B is usually ground.

I have not seen one wire diagram that shows a black with a white strip wire going to distributor or coil. Or a green with whit stripe?

Here's the diagram from the Body Electrical chapter, from the downloadable file on the site.  BE-4.

Sorry to be so in-your-face but it really was in my face as soon as I looked at it. It's from 1970 though.

Download away.  Sorry if all you have is a phone.  They're not as smart as the phone makers make them out to be.
