AE101 4AGZE SWAP, WIRING QUESTION Options

[JoKeRkId613]

Tomorrow I'm going to check out the 4A-GZE clip that I want. I've read a lot about the swap and the swap in other cars too. I have a question aboutt the wiring. How does that work? If I get the engine with an uncut harness... Would I have to rewire everything else in the car as far as the cluster and a/c control and all that sh it connected to the harness? Or can you just do the engine? That way I won't have to do any wiring. Because I always here people talk about how hard wiring is. With the 3S, for example. Since quite a few people have done it in the Celi, can't you just make a chart showing what wire from the 5s connects to what on the 3s ecu. I don't really get the whole wiring topic period. Can someone explain this to me? And if so, does anyone have a how to on how to wire a 4A-GZE. Or however that question is asked. Thanks.

Anyone? This question is kinda generic. This is the type of bullsh!t i'm talking about that i get from you guys.

i dont think people didnt reply to give you crap, its just that not everyone knows how to help you with your question

there are a lot of wires that need to be converted. its not a simple thing to just write down, because in order to do it, you have to know all the plug names, and have a basic understanding of how the harness works.

i would imagine that the 4a harness would be about as much work as the 3s harness, because you would have to rewire the fuse box and the interrior plugs. but the 4a wiring books are harder to get a hold of, the swap is less popular, and there are less people that could wire up the harness for you.

the cool thing about the 3s swap (besides the fact that its the most powerfull motor u can swap into our car ) is that its pretty well documented and there are a few people out there who can do your harness for you for a small fee.

Well, I just saw this post.

Here's how you do engine swap wiring: http://northeasterntuners.com/modules.php?...ewtopic&p=41714

You can't just have a chart showing what goes to what because every year of car and every year of 3SGTE is different.

Here' the how-to guide for wiring a 4AGZE:

Step 1. Send both harnesses and $350 to Phoenix Tuning
Step 2. Get harnesses back
Step 3. Plug in and go!

Soudns better than the $500 they were charging me here. How would I remove my factory harness? And how long would it take for you to do minus shipping/delivery time?

look, just because you don't get answers right away it doesn't mean you have to be a jerk.

it is simple. There is a wiring harness that plugs into the ECU, then goes to the engine, then plugs come off of it and plug into sensors on the motor, then it ends at the main fuse box in the engine bay. There are about 60 wires going to the ECU and about 20-30 going to the main fuse box (tweak correct me if I am wrong). You would need to splice a bunch of wires from one harness to match up to the corresponding wires on the other. You dig ? Do you know what color wire on your 7a harness is for the EFI ? or anything ? what about the same wires on the AE101 harness ? any idea ? Well Dr Tweak does, also DG. These guys have the information you do not have.

When you rewired the 205 cluster for your ST, do you remember how difficult it was getting all of the right info ? and making it all work properly ? An engine wiring harness is just like that except about 10X more wires and info generally changes from year to year so you would need the exact info on the motor you have and the new motor.

Also, if you make a mistake, like a wrong wire going to were it shouldn't you could burn an electrical system, or if you have a bad soldering connection you would be screwed.

edit : to remove the harness, you would need to remove the ECU and unplug the interior plugs from it, then snake it through the firewall and it is best to remove the engine from the car to throughly get it off.

Basically what Batman said, you unplug the ECU and pull the harness through, then disconnect all of the sensors and whatnot on the engine along with the places that it's held to the engine. Send me both harnesses and ECUs. It takes about a week usually but I'm pretty much booked for the month so I won't be able to do it until December.

Good luck with this swap! i had my swap started back in Feb and until today its still not running. Currently dr.Tweak is working with my harness so i'll let ya know how that goes. I have complete faith that he can do this.

Wiring is the biggest issue in these kinds of swaps. I know of only two 100% successfull gze swaps into a celica. As far as i know i am the first, i have a buddy I talk to online who recently got one into his 5th gen. There were a few folks around here workin on it but i dunno where it went to with them. Basically what it comes down to is that ur gonna need help with the wiring man, find someone who REALLY knows their **** about this engine electrically, u dont want any guessing involved. My friend with the 5th gen used the same guy as me, and he got his fired up a day or two ago. If you have questions feel free to ask, i'm not around here too much nemore so sorry about that.

[JoKeRkId613]

lol. so i guess 7afte it is...

[FAQdaWorld]

Its all about what you want in the end. You're gonna hit some serious limits w/ the 7a block, whilst the gze has the potential to build on (a lot, i've heard up to 400 hp on stock internals).

The gze is more work; but in the end yields more results but u gotta be willing to put forth the efoort into getting it done. Pay someone professional to do your wiring and you will be fine.

[JoKeRkId613]

cool. thats what i wanted to hear. lol. i didnt wanna keep the 7a. ok, so the ae101 should bolt up just like if i were putting in another 7a? as far as going on the same mounts, etc. right off the top of your head, faq, can you tell me some of the troubles you went through? what about the e58 tranny? thats bolts up too? thanks. i guess i'll pay someone for the wiriing.

[FAQdaWorld]

It wont bolt RIGHT up. if i can remember this right we used the front mount from the gze motor, the passenger and driver side mount from the celica, and we're gonna have the last mount welded into the frame. The driver side mount will need some modifications. I guess i really should put together a diary of everything that went wrong, maybe i'll start on that this weekend or something. If you're gonna use the e58 tranny then u'll need to have at least the driver side axle hybridized or shortened. It turns out the passenger side will work if u do it right. Make sure you buy a clip, as it turns out the axles for this bitch are a pita to get, everyone is lookin for them.

I'm trying to think of other problems that happened but they're just not coming to me.

[JoKeRkId613]

sounds good. that diary would be awesome. there's no mount on the botom of the engine. i think the gze on the levin came with a bottom mount. i dont think it was necessary tho. how did you go about shortening the driver side axle?

[FAQdaWorld]

Theres a rear mount on both the 7afe, and the 4agze, i'm plannin on welding the gze one to the frame tho. To shorten the axle you will need to find someone who is capable of doing it. Talk to a few machine shops, or axle specialist. Tell them you'll need an axle shaft shortened. I actually got my driver side from John (Mynezeyes (sp?)) so he knows for sure how much it needs to be shortened.
