Thanks I will have to think about doing it this way. It seems a little less complicated.

Robert, that would be awesome! Mine is actually a 76 even though my site name says "75V8." (my old z was a 75) Anyways, if you could just tell me about how you did your fuel pump wiring I would be grateful. Right now I have found the green-blue wire that goes to the Datsun fuel pump and have cut it under the dash before it went to the relays. I then ran a wire from that point through the firewall and into the engine bay. I plan on hooking that up to the fuel pump safety switch (Chrysler switch) once I install the engine in a couple of days. Yes I said it install will be in a couple of days...finally! Tell me if this is how you did it.

Well here is my 355 V8 after the Edelbrock heads were installed. It is looking good if I have to say so myself. The only thing I am worried about is the lash adjustment. I think I may have it a little tight. I will get with my engine builder on Wednesday to see what he thinks before putting on the intake. It is starting to come along nicely though and I can almost see the light at the end of the tunnel.

Sure send it my way.

Yeah I have the factory service manual but that will not answer my question. Where do you cut the wire to the fuel pump? I re read the JTR manual on the fuel pump wiring and it confused me more. According to the manual you should look for a black-white wire in the passenger foot well area not the green-blue wire...oh brother here we go again. I have spliced/cut the green-blue wire before the relay and plan to run that to the Chrysler fuel switch tonight or tomorrow depending on when I get my engine together. I have to put on the heads and related items and I will be ready to put the engine and tranny together and bolt them into my car. I will keep updating this old thread especially when I hook up the juice to see what happens. If I am successful with my wiring, I will make all 280Z owners the following promises: 1. I will never ignore another member’s plea for help on an item such as this. 2. I will never just suggest, "Buy a FSM" when I know the answer already. 3. If I do not know the answer I sure as hell will not just suggest buy a FSM! 4. I would be willing to drive (reasonable distance) to a fellow member's home to help him or her with the wiring issues. I am going back out into the summer heat today and knock this baby out! Wish me luck.

I too am at this place on my project. Me and my garage buddy (wife) spent the morning separating and hacking wires in the engine bay. We think that we have everything figured out except the fuel pump wiring. Bill you hit the nail on the head as for the JTR book being a little vague on the wiring issue. I have managed to find the green/blue wire (280Z) that it speaks of and have traced it from the fuel pump, where it starts out solid green, underneath the passenger seat to the cluster of wires going under the dash. My question on this issue is where do I splice into this wire. Does it matter? If I am not mistaken, the green/blue wire goes all the way to the Datsun ignition switch. Do I disconnect it there? I have discarded a lot of the original Datsun wiring and I am down to what the JTR manual says, “you only have about ten wires that go to your engine.†Any help on this would be appreciated. I will keep searching, but this thread is the closest thing that I have found to answer my question so far.

Thanks guys I am starting to get a little more comfortable the more I tear into the wiring on my Datsun. Larry the engine looks great so far, red block with polished edelbrock timing cover. I still need to put on my heads and manifold but right now I am trying to clean up the engine bay so the new engine will have a clean home to roost in. Phantom I exaggerated a litte on the wiring diagram thing, I can read them a little. I will figure it out soon...I hope.

Phantom, I have the factory manual...for me it is no help. It may as well have been writen in Egyption because I have trouble trying to read it as far as wiring diagrams are concerned. On another note. I traced my wires back into the harnesess and found that they change colors. So the JTR manual is correct when it says that the temp sending wire is yellow/white. You just have to trace it back a ways to get to the yellow/white wire As far as having the factory manual goes can't someone please just look at the picture I have posted as say "yes Charlie that is the right wire"

Tony, I think that the black/blue wire that runs to the Dataun coil has the power from the ignition switch and it is supposed to be connected to the "starter by-pass circuit" which is the Chrysler safety switch. I need to know if the wire that I have depicted above is this wire. I'm glad that you have different color wires in your Z such as I do. My oil pressure sender wire is also solid yellow along with the temp sender wire. According to the book they should be a different color. This is what has me confused with the black/blue wire at the coil. Could it actually be a different color I need to use instead? Also, do I just run a wire from the Chrysler switch back to the fuel pump and connect it? That's kinda what the book says but that sounds way to simple. As I said before I have 7 of the 10 wires identified and now with Tony telling me that his temp and oil pressure sender being a different color I now have 8 of the ten. Thanks Tony, I will look into the ignition switch location today. I am just getting going this mornimg after a long nite pulling the Datsun engine and transmission. Yes I am at the point of no return now. I'm sure my neighbor liked seeing another engine and transmission sitting in my driveway this morning when he awoke

I'm telling you Larry these 280's scare people when it comes to wiring them up This is and has been one of my greatest fears ever since I decided to do the V8 swap a few years ago. I have most of it down pat but it seems to be the first three that has me scratching my head. I have a step by step list from someone on this site but even with that it isn't clear enough for me to figure it out. I would still like to have someone close by stop in and check on my progress, especially since I am so close to getting it done. Mikekz, Georgia Z anybody...

Anybody got a clue? help help help

Guys, I have finally went and done it. I picked up my rebuilt Chevy (now a 355ci) from my builder today and have began the process of changing out the old inliner. Finally! Now if I could get some clarifications on the wiring issues I will be well underway. The wiring diagram on page 9-6 of the JTR manual is ok but not clear enough for a garage mechanic such as I am. I have a 1976 280Z and most wiring specifics are geared towards the 240. I need help on the first three wires that JTR mentions so here goes. In the picture below is this “wire #1 per the JTR manual? The blue/black wire the Datsun coil. It is the wire with the white tape on it. On wire #2, the manual suggests hooking up the black/blue wire from the 280z fuel pump to the Chrysler safety switch. The only problem with this is that I have a solid green wire and a solid black wire going to my pump. Where do I find this wire. Wire #3 suggests that it is yellow and black when in reality there is a solid yellow wire going to my oil pressure sender. I believe that I have all the others figured out. I am going back into the garage to prepare for the engine pull and will check back in a little later.

I took off all of the shocks except the passenger side rear. I did not want to drop the tank at the time so I used a cut off wheel and cut it off. I will however get around to dropping my tank one day to remove it permanantly. If you choose to do this watch out for the spraying oil because when you break through the metal with the hot wheel the oil will spray everywhere. Eye protection a must.

Larry, Great to see that you're back in it! Good luck and keep us posted.

As well they should be! Dont want someone without insurance plowing into me anytime soon By the way pop n wood is right. When your son is no longer in the house there is no reason to carry him on the policy. Get yourself some insurance and a good seatbelt for that beast and drive safely.

My engine came from a 1976 Chevy Camaro. The engine build date was 7/5/74. According to a website I visited once the horsepower of that engine was rated at 145 hp with the 882 factory heads. So Wheelman was probably close on his horsepower assumptions. By the way I am glad to see that others have bought the headers from ebay and they have worked for them. I too have these same headers, new in the box, and wondering about the quality. Thanks for the product review.

Here are a few pictures from the Hooters Meet today in Norcross, GA. It was nice to get out and meet some fellow Hybrid Z members especially when one came all the way from Australia. The black 240 with the bright green racing stripes belongs to Mike kZ of course and the black 280 next to it is mine. This is a picture of an awesome Mercedes Benz with a 383 Stroker motor installed between the fenders! Belongs to a member here, (sorry I forgot your name), that came out today. This is one clean Hybrid!

This is a quote from one of his pathetic sites. You know this *** needs to be erased from the face of the planet! I went to the above links and read some of his rant about the American Soldier and it made me boiling mad. To think, an American, living amongst us could have and foster such slanted and hated views on our beloved soldiers is an outrage.
