Need some help with electrical wiring from scratch...sort of...

Recommended Posts

I recently purchased a 76 280Z as a roller with no motor or tranny and a great deal of other missing items. The plan is for a VG30 conversion which will be wired independently of the 280z's stock chassis wiring. In an effort to reduce, uh, effort I would like to retain as much of the stock chassis wiring as possible (if possible). Here are two pics of the remaining wiring harness and it appears there is quite a bit missing. My main questions:

 

1) there is no positive battery cable. But there is a white 10 ga. wire which appears that it may the main feed to the ignition to provide power to the fusible links and subsequently the lights/wipers/horn/etc.?

 

2) Did the 76 come with an external voltage regulator (which is not present if it did)? Have searched but not found concrete info.

On my '76, the white wire in the picture is attached to the hot post on the starter, which should have a cable from the positive battery terminal on it as well. From the positive battery terminal, I also have a white wire that goes into a connector and comes out as a red wire. This red wire meets up with another red wire coming from a similar connector on the negative battery terminal...

 

I think the white wire is spliced into two, then again into four white with red stripes that feed the fusibles.

 

I also think that we do have an external voltage regulator.

 

Anyway, congrats on your purchase and I hope this helps!

 

P.S. Nice battery tray.

P.P.S. If you don't have it already, download "The Fuel Injection Bible" (280Z specific) and the '76 FSM.
