82 pickup 3rz Swap DD

[Sparkplug]

Been gone for a while. Been busy working. Still building tho.

I got this 82. I've always had a thing for first gens. But ever since owning tacomas and my current taco, I can't stand the power of a 22r. So out it goes.

Goals here are a truck that appears stock,  gets 20-22mpg. And is comfortable to commute to work in. I won't be wheeling it  I'm actually going yo get all the body work done and get it painted. A semi restoration.

My rz is from a 99 auto taco. I got everything but the fuel Lines. I'm in the process of getting a w56 trans, and I found a w59 bellhousing. I'm going to buy the flywheel and clutch kit new from aisin. Other than that I'm pretty sure I have all the main parts.

Pics are where I am right now. Had the 1st gen exactly 9 days.

I'm about to start on wiring. I'm first going to eliminate all the auto wiring from.my engine harness. Someone please correct me if I'm wrong, but I basically just get a book, and everything from that harness besides the reverse lights and 02 sensors, I unpin from the plugs at the ecu, and remove the wires. Correct? Sorry. I've never done a swap like this wiring myself. Always was the easy way and just drop everything in from the donor.

Also. Lilbuddy mentioned in a rz thread he paid for a 3 day membership to a site that gave him colored wiring diagrams. Does anyone know what site this is? Any information or criticism is appreciated.

My 83 is running an auto 3rz as well but frim a 96 taco. My friend did the wiring but all that's left on trans harness is the 02 sensor wires, reverse light switch, and 4wd light wire.

Let me know if you find anything out about that wiring diagram. I'm doing a 95 3rz swap onto my 83.    I'm about to get into the wiring. Kind of scared to touch it Bc I'm not the greatest on wiring stuff 

And what are you doing for your gas tank?  Swapping tanks or what?

[Sparkplug]

I'm going to put the tacoma pump and sender into my carb tank. I've done it before on a 22re swap and it worked fine. I'm also going to just run efi rubber line for my fuel line from tank to engine. I did it on my last 2 crawlers and it worked fine. Survived multiple rollovers with no leaks at all.

looking good, backing plate link sent,

What are you doing for motor mounts?, as for trans harness i left everything intact but just plugged in o2 sensors and cut and spliced in my old w56 reverse light switch in place of the tacoma one, i do have a check engine light for vehicle speed sensor though

[Sparkplug]

I'd rather not have plugs hanging if I can avoid it. It should be pretty easy to eliminate them.

I'm hopefully going to combine the rz and 22r mount. I heard chilkat mounts have alignment problems. I'd rather not pay 150 bucks for mounts just yo have to add shims to them. What did you do?

I actually sprung for chilkat mounts since i have no welder and was on a time crunch before mcr and believe it or not the motor sat perfect, i guess i got a good set or they fixed the problem, no shims or anything

[Sparkplug]

Ok. I'll call them and talk to them tomorrow. If they have fixed the issue I'll probaby go that route. I also got to looking at my engine harness, and I'll have to tear into the tape and looming pretty heavily, including somehow getting the rubber off where it mounts to the cab, to get the wires out. I don't know what would look more hack, leaving the auto plugs, or taking them out and having a reaped and loomed harness? Any opinions?

[Sparkplug]

How about this idea? I de pin them at the ecu  plugs, and just undo the loom that runs down by the trans, and cut the wires  out as close to the main harness as I can, leaving the wires I do need?  Then I could just re loom the trans harness, and no one would ever know?

I have that same check engine light for vehicle speed sensor. Do you think it causes any negative effect?

[redneckcustoms13]

I don't have that code, my ecm is reading it off the back of the gauge cluster. I don't think it would have any effect on timing or anything but who knows.

Did you utilize a engine/ecu out of an auto or a manual? I think its only people who use an engine out of an auto that get the code.

[redneckcustoms13]

My engine and ecu are from a 96 4wd auto taco. The gauge cluster on all of our trucks has 2 screw or 2 male spades that can output your speed to the ecm.

Have you checked to see if it is throwing the code by hooking up an OBD2 reader? Mine doesn't illuminate the check engine light (probably because the shitty shop that did my swap didn't do it right and my check engine light doesn't work) but it is there when I hook up the reader to it.

[redneckcustoms13]

Yea the only codes I get are for shift solenoid failure, and 2nd 02 sensor because it isn't connected.

Call the Toyota Material Distribution Center.  Hopefully you have the VIN off the donor motor.  You can order from them VIN specific wiring schmatics from them for $17 each.  This was years ago when I ordered mine, but I am sure the price is well worth it, and you get to keep them forever.

Got the body harness from taco ecu to my 1st gen done. Still have to tear into the 1st gen and eliminate everything that relates to the carb. And I haven't decided if I'm going to use the taco fuse box, or make my own. I also realized I don't think I have the harness from the fuel tank to body. But that should also be fairly easy to make if need be.

I included a pic of the wiring from my diagnostic plug to the e5 and Ik2 plug. It's tied to both. I unpinned it all intact because it appeared to have shielding on it? Do I just keep it like this when I hook it all up? I didn't see this mentioned in any of my reading. Common sense just says wire it nicely how it is and loom it. But I've assumed in the past on things and it's bit me in the ass. I'm learning as I get older to try and be patient and humble.

[Sparkplug]

I kept my vss wire. I will wire my truck to not have any codes and run as intended from the factory.

[SqWADoosh]

The engine needs the vss signal for a few reasons one of which is the ECU needs to know if you are moving when you decelerate so it can ignore the lean condition that occurs on decel. also it knows it can cut the fuel to the injectors at that time. Without the signal the truck will "buck" on decel and waste fuel not to mention the possibility of throwing related codes such as lean. it's very easy to find and connect.

Where is it? How do I connect it?

[Sparkplug]

It's green and orange wire on e5 plug. It connects to the back of the speedo. You have to adapt your speedo and possibly the sender at trans. Someone correct me if I'm wrong please. Thats how I understand it.

Would really love a detailed explanation on what to do if LO or anyone who has done this can help me out. I've wondered why I get such shitty mileage and why my 3RZ has never felt as smooth as it should.

[Rockcrawlintoy]

What mileage are you getting again?

[OVRAROK]

95-97 vss, has 4 pulse output signal and a mechanical Speedo cable, this might be your answer

[SqWADoosh]

What mileage are you getting again?

14-16 in the city. Barely 20 on the highway.

[Rockcrawlintoy]

14 to 16 is about what I was getting around town and I got 22-23 highway doing 55-60 seems pretty reasonable mileage for a big tired brick.

I'd still like to sort this and see if I see improvement.

i posted this earlier in this thread. i can help you further if you can't find it http://board.marlincrawler.com/index.php?topic=95785.msg1087668#msg1087668
sorry for the thread hijack. my vss info is for 84 and up. i don't have experience with the first gens

This sentence doesn't make sense. "from attached pic plug b pin 4 green with a blue stripe. could be the same location as your gauges if they are at all similar."
