Trans/starter/oil switch + Thermal switch / trans vac switching valve

[robftw]

Well, i was going to splice the wires but after looking it over i chose not to.. i'm looking for a good Zcar junkyard to call up / go looking.

I've been over google a few times, and i've emailed a few people already. However its been 5 days no reply.. I'm starting to get desperate because these are all i need to drive the car.

Here are pictures, and wiring diagrams of what i am looking for in case anyone has them and would part them.

I'm guessing you have a '77 or '78 automatic? (You need to tell us.)

As far as I'm aware, Z junkyards are very few and far between. I think I saw photos from one in Arizona. These cars are usually stripped and their parts stored. The best marketplace for used parts is probably Ebay. (Beware Reddat. Do a search for Reddat on this forum to find out why.) Courtesy Nissan is probably the best mail-order source for dealer parts, some of which are still available. There are several mail-order/internet businesses that you can check -- Motorsport Auto, Bonzai, Black Dragon. Also don't forget your local auto parts store (e.g. AutoZone). You'd be surprised how many Z parts you can get from them. The parts are all out there and for sale, for the most part.

76 manual with a 77-78 engine

edit: I tried MSA, Black dragon and courtesy nissan. None of them have the harness i need, or the proper connector so i could make my own without cutting wires.

I googled bonzai and ALOT of sites came up, which one is the right one? I even tried that texas Z guy, He might have one in the one wiring harness he has but it is so jumbled up its hard to tell

edit 2: I bought stuff from reddat once on ebay and i will never do it again, it took two weeks for a radiator bottle to arrive. I could have drove there and back in that time.

Well, I recognized the '77/'78 engine from the pics on your first post.

I guess I'm having trouble figuring out specifically what you're trying to find (Trans/starter/oil switch + Thermal switch / trans vac switching valve). Perhaps you're using unfamiliar terms, or perhaps I just don't understand how you're combining and separating the terms with "/" and "+". Are these the terms used in your factory service manual? (You need the FSM for the year of your engine. Find it here: http://www.xenons30.com/reference.html -- downloadable for free.) If you aren't certain of the correct terminology, perhaps you could tell us what the parts do.

I believe reproduction wiring harnesses are available, but I don't know where they can be found. Perhaps Dave (ZsOndabrain) might know. He's the wiring harness guru here.

You can find vintage Japanese electrical connectors here:

Here's Banzai Motorworks:

There's no harm in splicing connections if you do it well. Opinions vary, but I like to twist, solder, and heat-shrink on low-amperage connections and crimp, solder-sweeten, and heatshrink on higher-amperage connections. Then I wrap up the harness with electrical tape when I'm done.

To make it easier, i need sub harness labeled C-13 (top harness diagram) and the sub harness C-14 (bottom harness diagram)

Honestly, if I were you, I'd just make the subharnesses myself out of different connector styles. I found a water resistant connector system out of Hong Kong that I can highly recommend. You can get them on Ebay. Here are some 3-pin connectors...

...but you can buy from 1-pin to as many as 6-pin, last time I checked. The seller's name is 2allbuyer.

The connectors are very sturdy, made of reinforced plastic with silicone rubber seals. They're very economical. The seller put together a package of several of each pin configuration for me. To my disappointment, the silicone rubber seals were a bit too small on the 2-pin connector, but were fine with the 3-6 pin connectors. I left the guy good feedback, but I pointed out the problem to him. I asked him to send me a set of rubber seals for the 2-pin connectors if they ever became available. Somewhat to my surprise, I got an envelope with the seals later -- even some extras. This seller has unusual integrity!

I'd say the connectors are good for a few amps per contact -- probably adequate for everything I see in the subharnesses. You might use bullet connectors for the heavier current items like the starter wire and the reverse lamp.

Just bought them, hopefully they arrive quickly EMS is usually 5 days for me here in NY.

Wow, they showed up today this guy ships fast!
