Thanks. Here is a pic of what I believe is the ignition switch plug. The problem is the diagrams I've been lookin at don't match up with what I have. Meaning my wire colors are not the same as any of the diagrams I've looked at. Any thoughts?

Okay very crude drawing, but any info would be great. So far this is the plan. Obviously the smaller things are not in the drawing, but just a general over view. Is there any issues doing this? The 2 fuses i put on the drawing, one says main. On the factory 2jzgte wire harness for this system uses a 50amp main, and 120amp between the charge stud and battery. Is this good?

Awesome, thanks

My AE86 Corolla does this too.

Ok another question. The aftermarket chassis harness has single wires for lights and things, obviously they need to be grounded. Stock connectors in most vehicles have 2-3 wire from the connector. Do i just make my own grounding harness to tie all the grounds? Cuz in the instructions there is no mention of this. Maybe its common knowledge among electrical guys but i just realized it now.

Yes it has a fuse block with it and yes its like your painless, I don't see an EFI circuit. It does have an "ING COIL" circuit, but I'm pretty sure I'm not using that correct?

Body harness is from EZwiring. Ill have to take a look at the engine harness again to see if its hooked to the alternator.

Okay, this is long overdue. I've been working on and off on this 260z for 9 years. I put in a 2jzgte and pretty much nothing is stock anymore. I purchased a wire harness for the motor and new aftermarket body harness. I just have to figure out how to hook everything up properly and safely. I'm in not way an electrician and my knowledge of the subject is limited. I discovered that a bunch of info on the Web is conflicting or deals with domestic vehicles more than imports. From my knowledge talking to the harness builder for the motor, there are only a few wires to hook up to get the motor running. There are already fuses for the fused circuits. So, when I'm laying out the body harness I see "ING coil" wire. I believe there is already a fuse for this on the engine harness. Same issue with alternator. My question is should these 2 harnesses be kept separate? One is body electrical and the other motor, so they don't really need to interface anywhere, right?

Is it the GPS one? To me that would be the easiest, thats what I am using. Sometimes you can use a sender of some kind that plugs into where the cable goes into the tranny, but not sure if that is available for that transmission.

If we have a pre 75 smog exempt car we dont need to stop at those check points?

thanks for the help figured it out with the help of another member.

Awsome thanks

thanks for the reply, but do you think that going down a size will effect how the booster operates?

For those of you that have completed a 2jzgte swap in a S30 how did you attach the 3/8" vacuum hose to the intake manifold. That stock motor uses a banjo attachment and if I use it, it might contact the hood. My engine did not come with this banjo attachment, it just has a bolt there to block it off. Any suggestions? I just dont want to make more work for myself, by taking off the intake manifold and drilling and tapping a new port.

Okay, I have a 260z and I know the brake booster vacuum hose size is 3/8", but I only have a 1/4" nipple available on the intake manifold. I swapped in a 2jzgte. Can I just use a 3/8" to 1/4" reducer or will that not be sufficiant? I really don't want to pull off the manifold to drill and tap a new hole if I don't have to. Thanks

Okay thanks I did buy an aftermarket fuse box with all the wiring hooed up, sorry might have forgot to mention the wire part on the first post. So, i hope the wiring that came with the kit is acceptable. I am not doing anything crazy, sound system huge amps and stuff, im bot even putting a radio in. I am using a 140 amp alternator that comes with that engine (internal regulator). Yeah I did read about the head light relays, so i will definitly run a couple of relays for those.

Thanks for the site, but I can't seem to select that part of the web page. I might need to look on my desk top at home. Yeah I really don't want to make mistakes with the wiring, even if Datsun made them, lol. I have bought 2 how to books, which are very informitive, but i'm the type that has to have everything laid out to see it. Hopefully it will come to me when I physically lay everything out.

Thanks for the replies, i'll look into it.

Okay, i've been stuck on this part of my project for a little while and have just been avoiding it. I am not an electrician so my knowledge is limited. So i have a 74 260z with a 2jzgte in it. I have a new engine harness that I had someone make for me. I purchased a pre made wiring harness with fuse block for the body. I kind of just need to know the basics which I really cannot seem to find. 1) I will run heavy gauge wire from the battery straight to the starter, correct? 2) also run a wire from the battery to a fuseable link or maxi fuse then to the aftermarket fuse block, correct? So, this will power my fuse block. Now the majority of other things, lights, fuel pump, gauges, etc will get power from the fuse block, correct? 3) I understand that relays are switchs and that they use low current to power larger current items. Example. When wiring up the fuel pump, im sticking a relay between the fuse block and fuel pump? So, I am powerig fuel pump with the relay and the power to the relay comes from the fuse block? Sorry if all these seem simple, but I want to be sure I do it correctly. Last thing I want is for the car to catch on fire.

Thanks for the correction. I didnt know that the stock cap let air in, good to know. This might make it a little easier for me. Thanks

Okay so ive been combing the interweb with minimal results. When talking about eliminating the vapor tank, ive heard people mention " just get a vented filler cap" to vent pressure in the tank. So , i assume the stock cap is not vented. And ive searched for vented caps to fit the early 260z tank, but come up with nothing. So, what are you guys using? I know some use a breather filter but i want to stay away from that. I found a pressure relief vale made by fuel safe that seems perfect but i need to buy fittings to make it work. Anyone know what vented fuel cap will fit this tank?

I think I got it from jegs.

I thought about the 2 45 degrees, but didnt think it would look good. I think I might be a bit too anal about the issue but I have a feeling if I just do whats easiest It will bug me and I will redo it anyway, lol. Here is the pic. I can maybe modify the prebent 90 degree and be happy. I just wanted to know if there was anything out there that was a more gradual bend.

Ok so im looking for a very gradual bent piece of stainless, 3", 90 degree. The largest radius 90 degree bends i see for sale is 8" radius, which is too tight for my purpose. This is for a down pipe from the turbo. i tried a 8" radius 90 degree pipe but its too sharp for my liking. Im looking for something thats been ring rolled, or something similar. Does this make sense? My other option is to make one by cutting a bunch of angled pieces and weld them together myself, but thats a ton of work. Any ideas?

I know this seems like a stupid insignificant question, but i could not find it on a search. The one screw that holds the speedo bezel and tach bezel, anyone know what size it is? My dash was missing these two screws when I bought it and the nut is captured in the dash frame. I think its a small machine screw but I cant tell. I would think its a metric machine screw, is that a safe assumption? That way i can go buy differnt sizes and see which one fits if no one knows the exact size. Thanks
