snork Posted September 25, 2010 Share Posted September 25, 2010 Well, I finally have the motor and (5sp)tranny out. Now I am stuck on the wiring. I have the computer and harness completely out and I am now trying to figure out the harness on the passenger side of the car. Which wires do I need and which ones can I junk. The motor i am using is a 1980 302 and I have the "brain box" that came with it. I am also wanting to be able to use the factory ac, so I have left all of that in place. I have a wiring diagram for my '77 z. I need help big time, mainly cause I am starting to freak out! I am using the ford altenator. I have the JTR book, but most of the wire colors dont really match up. Quote Link to comment Share on other sites More sharing options...
erehemantresni Posted September 26, 2010 Share Posted September 26, 2010 Where are you located? I had the same problem with my 78 280z. The later cars had different wiring colors. This website has a 77 280z wiring diagram. http://www.4moores.com/280z/files/index.html Helped me a lot. Good luck! Quote Link to comment Share on other sites More sharing options...
snork Posted September 26, 2010 Author Share Posted September 26, 2010 I live in Montana, near billings. I have a wiring diagram, but like on the voltage regulator I have two blue wires. Which one do I use to connect to the altenator per JTR manual. Plus, can I permantly remove the two fusible links on the pansenger side of the car. Plus, how do I hook up the brain box? How did you hook yours up erehemantresni? All I want to do is clean up the engine bay except for the wires I need and the ac. Quote Link to comment Share on other sites More sharing options...
erehemantresni Posted September 27, 2010 Share Posted September 27, 2010 I used a carb. And a gm 1 wire alternator. Unfortunately I have never read the JTR manual. I also got rid of the factory ignition box in the passanger footwell area. Sorry I cant be more help. Quote Link to comment Share on other sites More sharing options...
erehemantresni Posted September 27, 2010 Share Posted September 27, 2010 Thinking about this, you could build your own starting/charging circuit and ignore/remove the factory stuff on both of them. That would be the easiest. Did your car have a factory external regulator? Quote Link to comment Share on other sites More sharing options...
snork Posted October 1, 2010 Author Share Posted October 1, 2010 Ya, It has the factory external regulator. I have been able to remove all the wires except a yellow one. Its a yellow wire on the harness, then it turns into a white wire on the regulator's side of the connector. Do I just cut the wire (taped off of course) and leave it be?
