When I wire the fuse box I use these fuses boxes and what ever relays I can find with the handy tabs, makes them easy to mount.

like this when its installed (pic in a dime passenger foot well)

The fuse boxes contain 6 fuses so if you are going to run other stuff besides the ECU and fuel pump thicker wire isn't a bad idea. Remember Tesla vs. Edison? DC current looses its gumption over short distances.

Thanks guys. I think that clears some things up. I have more questions but I will reserve them until I do this next week and see how it all pans out. Thanks again.

Here are pictures of the relays I got...

Mine seem to have five connections in the back.
On the front it has a diagram to what each point goes to.

My Question is how does the first picture of the relay diagram relate to the diagram you guys have of the wiring.

For example: point 86 would go to power cable, point 87a would go to fuse box... etc.

Get what what I'm saying? It's confusing because I don't know how these things work so I don't know how to read it. Thanks guys!

Thats a "Hi,Low" relay for headlights. I could work but not optimal. You need standard relays unless you want an extra pin for no reason.



30 comes from the fuse box then is switch from 87a to 87 in your case. 85 is the ground for the switching coil and 86 is the power. Hopefully that clears some stuff up for you.

pin 85/86 is the low current path to trip the Relay. Some are polarity sensitive some are not.

87/87a and 30 is the high amp contacks
Throw on some Weber sidedrafts, Rising Sun hood.... call it good

I always ground 85.

So I assume that I would use 87 to power... let say the fuel pump and not use pin 87a right? Then I would just leave 87a blank...right...

Well after everything is said and done I made my own wiring diagram. Improved from the nice one already made with a more clear understanding of the relay. Also it's in PDF format for a nice clear picture. Again thanks for all the help guys. This is going into a 280Z just in case you were wondering...:eek:

WOW! That's clean. What did you create the drawing in?

Damn that is one nice drawing!!! It puts mine to shame thats for sure :D The only thing I think should be changed is the optional kill switch. Where you have it puts it on the high amperage side of the circuit. If it was only cutting power to pin 86 it would be better because if someone used a cheapy low amperage switch it wouldn't burnout. A good quality switch to handle that kinda power is hard to find these days. Well from any local store that is... Radio Shack is a joke if you ask me.

I should really go through and find the exact colors for all the engines and make sure they are right. I should also add the s14 and 15 models... Its just time..

O and the amperages for the fuses I just kinda made up :D After talking to Rob it may be better to run smaller ones.... I'm no electrical engineer.. Maybe I can get him to post here.

1 last thing, did you post your car in the project section? I want to see this beast! :D

Please do. Post that shit! :D, I'm lost without the assistance of experienced help. Plus I always make it a point to let other guys fuck up first before trying it myself :lol:

interior:
re-upholstered seats from 1970's 280Z, custom shifter boot, and center console
sound system:

That diagram is very nice. Great job on it.

Now if only someone did one like that for the VG30 swap.


Does anyone know of one for the VG30 engine??

Also, I've determined, I'm not a hoarder, I'm a collector.
As I'm sure a lot of the old school datsun guys are.



Enjoy the Ride!

electronic concentrated control system.

Not exactly sure the difference in that and the ECU but I assume IMO it's the same thing.

I can change anything you think I should change. What would be the recommended fuse size? 10A?

When you mean the high amp side of the current for the kill switch, should it go on the other side of the relay? Cutting off the current the relay sends to the harness?

I can post the car when I get some pics done. I have pictures of the L28 coming out but the car is in a utter mess right now since I've taken it completely apart.
