Nice work.
You got a great deal on that blast cabinet.
I bought the same one when I went in Harbor Freight and they had a special on them, and I also used a 20% coupon.
I think I paid a little over $100 for mine.
It sure is handy.  :afro:

Definitely, I've been using a portable one and it sucks.



I was supposed to get the fuel hoses done, I ordered 5/8" and was sent 1/4" so I'm put off another week from finishing my fuel system. Still have plenty to do so next on the plan was to get the wiring done. This week I was able to get the rear section done. This is the first time I ever rewire a car and I think I'm doing pretty good from the condition the wiring was in before. I reused the old connectors with new terminals where I could instead of splicing new wires with old wires. It doesn't seem like a lot but it took a lot of time to research and plan what wires from the EZ harness goes into factory locations. Next week I'll have the front finished then may need help from a buddy to do the ignition and dash.

I'm just saying, if I ever get rid of this car the next person will get a deal, the interior has been stripped, POR-15'd and Lizard Skin'd, new wiring and new interior ready to go in. And that's just a start.

LOL "you're my boy, blue!"

You know, its bad enough that you make me want to work on a car. Now you got to add making me hungry and thirsty on top of it all! Evil... just evil... especially the sweet tea part... damn you! :cheers: :chug:

I'm loving those side edits to the videos, lol. Very entertaining.

Nice work on the wiring, and very entertaining video.   :afro:
One tip would be that there are better crimp tools out there if you're going to do a lot of wiring.  However, they can be quite expensive, so not usually worth it unless you use them a lot.  eg: https://www.newark.com/amp-te-connectivity/58628-1-cal-d/ratchet-hand-tool-26-14awg-contact/dp/08AC2373?st=crimper

Another thing is a heat gun is much better for heat shrink tubing. 
I use this one from Weller:   https://www.newark.com/weller/6966c/electric-industrial-heat-gun-120vac/dp/35F3074
It's faster and doesn't scorch the tubing like a flame can.

I'm usually the type to opt for top tier products but find it hard to swallow spending that much for a mechanical tool when alternatives that cost 15x cheaper with lifetime warranties are available and perform equally well. For many mechanical hand tools the users technique holds more value than the tool itself. For example a master welder could toss out better welds using a cheap chinese gas-less welder than a novice welder using one of millers top gas welders with the latest autoset feature. That said I've had great luck with the chinese b-crimpers sold online. I've had good experience with IWISS and have every crimper to perform B crimps ranging from 28g to 0g. I love B crimps. I feel they are the best type possible because you can crimp the wire and the insulation. Good crimps on the wire is important for obvious reasons but crimping the the insulation is often over looked and if you see whats readily available at autoparts store they don't normally offer terminals that crimp both. The insulation crimp helps with durability especially when your working with thin wires that are more prone to breaking after manipulating them only a hand few of times. Linked is one of the chinese B-crimpers offered online. Also attached is the B-crimps i've done with the iwiss crimpers. Again if the wire is thick longevity of the connection should be pretty good but for thinner wires I'd recommend finding terminals that crimp both the insulation and wire.

I hope I don't offend you in anyway, cobra. I'm just tossing my opinion out there with an alternative option for unleashed to ponder about.

Groove, that looks like a great deal on those crumpets. They look very similar to the Amp ones I have.
Mine came from a former employer that was closing.
If I were paying for them myself I'd definitely give those a try. 😊

Trying to mix it up a little instead of having time lapses for days.

If I do a whole car again I'd certainly consider one of those, I'd do a lot different in fact.


A fellow FD owner stopped by during the week, he offered to work out a deal on a CYM (salvaged title) for the 280z, was very temping but I waited a long time for an S30 that wasn't completely rusted out to come a long in my area.

Moved on to the front of the car, mainly the lights and horns. Will be deleting the side markers in the future so I didn't bother splicing them in the loom. I couldn't run wires directly to the turn signals, they have to be spliced and aren't pretty but you won't be able to see it from an airplane. After cutting wires to length and attached connectors I wrapped the front section, but I'm not a rapper. The alternator is wired, the starter needs to be finished, I need to find out how an HEI Distributor system works to finish that. The battery is in place and just need a few more wires added to it, its coming along, it takes me hours of planning and research just to get a few minutes of work done, sadly.

Next time I'll finish up under the hood and connect my fuel hose since it came in. The plan after that is to knock out the dash then move on to installing the rest of the interior, Sooooooooo CLOSE. Then of course there are things like paint, coating the wheel wells, 5 lug swap, manual swap, so much to do, but that can be done while the car is drive able.

Red goes to key hot run 12v ~10ga wire,  no resistor wire or blocks needed.
green is tach signal wire

Thanks, that will be a big help. I should be able to pick up one of those at a local Auto Store. I have a spare wire labeled "Coil" that may be for the red wire, I'll double check and see where that pigtail would plug into. The PO had a wire spliced into the distributor which I'm now guessing was for the Tach. The diagram presented in the E-Z Harness manual is for a points system.

The pig tail socket is on the drivers side molded into the cap near top.  Pig tail will socket up into the cap locking tabs away from the distrib.  Caps are normally marked coil toward front of engine and tach toward firewall.

Hei draw more power than points so an upgrade to ~ 10 gage is a good Idea.  Hei was designed to run full 12v no resister, it will run off of resister but will have poor spark

There is a 3 wire harness from the distrib to the cap (same side as power and tach but closer to cap. It should have no splices.

That pigtail was a huge help, I could have used lugs and all but I didn't even know the connector was on the underside of the cap and I was stuck on where those wires needed to go.


I found where the HEI pigtail went and spliced it into the harness which was tach and coil pos, got passed that wall I was stuck behind. Worked on wiring the fan switch, this was a little bit of a project on its own. The diagram included didn't match the instructions on the back side of it but figured it out. I didn't originally plan to have one or I would have ran the fan wire through the passenger side, all good though.

The E-Z manual had no instructions on how to wire the starter so I referenced the Painless manual and asked around, just needed to put the Ignition Switch Start (Purple) to the prong on the right side of the solenoid and the red was optional to the starter power or battery, I went to the battery.

Circled back around to putting the fuel hoses on the tank and deleted the Evap Tank. I'll probably clean up a few wires on the pump and sending unit another time, while I was under the car I saw that they were also as messy as the rest of the car originally was.

Overall I could have planned better but very happy with everything so far. I looked at the before and after of the engine bay and it is sooo much better now and I won't have to be scare of something setting fire.

Fig Tree, been wanting one, can't buy figs at produce stores around here.


Since I created a logo and had some heat transfer vinyl I tested it out on an old dry fit shirt and the test was successful.
I grouped the wires required for the ignition switch and put them in a 6 slot connector, there is a total of five wires to go to the ignition switch. The ignition switch now has power, I thought the engine would start right up but I was wrong. I figured maybe the battery was weak since its been sitting for a few months, I put it on a charge but the engine still wouldn't start, just turns over. While the battery charged I mounted the shifter. The fuel pump primes and pushes fuel and I put fresh plugs in and still not starting, I also tried starting fluid. I'll try to figure out what the problem is, I'm a little disappointed, I wanted to have it ready for a car show next weekend. I mention in the video that coil pos is top left but its top right, the car is briefly starting, I'm so close to having it running.
