are you having harness trouble?

Yeah basically the 5s is ready to come out I just don't have a hoist so I want to work on the harness for now but I don't know where to start. I was trying to understand the post on your thread but I don't really get it. Someone offered to help over the phone but I didn't get around to it on saturday I think pics are a little more helpfull to me cuz I'm a visual learner but any help is greAtly appreciated

Here are the USDM plugs inside of my car where the harness for the BEAMS plugs into after the ECU. On the gray plug (1st gray plug in the pictures and 1st gray plug from bottom to top when you look inside the car) everything matches except one wire The white plug is missing wires. and the second gray one at the top is just a mess. I'll post pics now and edit it to clean it up later when I get a chance so you know which one is which. but just in case you already know the difference I'll post the pics now...

ON THIS ONE EVERY WIRE MATCHES WITH THE JDM PLUG EXCEPT THAT THE JDM DOESNT HAVE THE BLACK AND BLUE WIRES THAT YOU SEE SEPARATED ON THE UPPER LEFT OF THE PICTURE


ON THIS ONE (WHITE), THE WIRES ON THE WHITE PLUG THAT ARE SORT OF SEPARATED TO THE LEFT MATCH WITH THE EXCEPTION THAT ITS MISSING A BLUE WIRE. THE BUNCH OF WIRES SEPARATED TO THE RIGHT ON THE WHITE PLUG ARE EXTRA COMPARED TO THE JDM WHITE PLUG


THIS ONE IS INSANE MOST OF THE WIRES DON'T MATCH

the wires may not match, beams may have different colors

this is what i have and others have done

extend the maf wires, the speed sensor wires and the vacuum sensor wires. (at least what i did)

on EA1

bridge together pins 4 and 17
bridge together pins 2 and 12

move white plug (pin #18) to dark grey plug into (pin # 17)

For Cruise dark grey interior harness (pin #10) tap into blue/white stripe wire from the ECU (AFaIK this is not working, as beams did not have cruise, Batman722 is working on this and i will probably not use it)

For SRS run a wire from EA1 through the engine harness (or body) to the light grey interior plug (pin #5)

this is all the wiring to be done...

all the wiring im doing is rerouting and extending the harness.

pm me your email if you're still interested and ill forward his reply. he said he has it for 119.99

he said something weird but idk if its true.

Here are pics of the differences in the fuse box...

The Top one is from the BEAMS harness the bottom is from the GT USDM. The fuse differences are obvious but on the gray plug (bottom left i believe this is the EA1 everyone talks about) there is an extra wire on the BEAMS one that the USDM doesn't have. anyone know what thats for? Everything else matches

Same here but a closer look.

JDM: WHAT THE HELL IS 4WS????

thats for ST203 with 4 Wheel Steering

the rare GT-R

nope the ST183 models got called that but the ST203 didn't. They had a '4WS' sticker on the back window, where the "Superstrut Suspension" usually is.

Ok i believe that engine might be from a curren possible, some were equipped with 4ws, but you dont have that, i believe that extra wire is the wire that goes to the injectors maybe, that one that you have to bridge, or an extra ground, but im leaning towards the first one. what color is the wire. black with red?


the pplace in the beams that says trac yours is srs, thats the blue wire missing for the airbags.

thanks for the pics posted in my post.

Yeah the extra wire is black with a red stripe. what is that for?

What is the trac wire for? Do i need it, keep the trac slot and run a new SRS wire to a different slot or do I run the SRS wire to the trac slot and delete the trac wire and fuse?

i think it has to do something with the injectors, and the trac wire you can use it as the srs in ours, is for the indicator light, you just have to repin it

What about the interior wiring from the auto shifter? You need to bridge the park/neutral switch wires in the plug that goes into the auto shifter to the clutch start switch, otherwise you are going to have some trouble starting it.



And this step is for a car that came with a manual transmission. Having an auto interior harness you are most likely going to have to put this wire to a different pin.

What color wires are those for the shifter do you know????

The easiest way to do it is in the engine bay at the park/neutral position switch that plugs into the auto tranny, but since you are going to be replacing the whole engine harness you'd be getting rid of that end, so you need to do it on the interior side.

Its a black wire and a black/yellow wire but you need to connect one from the harness side to the other one from the ECU side and I can't remember which way it goes. I think its the black wire you cut that comes out of the ECU into one of the three interior plugs and goes into the harness behind the console, then you cut the black/yellow wire from one of this shifter plugs and connect it to the black wire (this will make it so you can start with car without using the clutch) OR just route both wires to the clutch start switch on the clutch pedal (doesn't matter which one goes into what pin cause it just connects the two when you push the clutch in).


This is the part that throws things off a little. The above wire moves the Beams clutch start wire from the engine to the GT clutch start switch in the interior. I'm not sure, but you may be able to bypass that whole step I mentioned above and just repin a different wire for this step. Either way you are probably going to have to move this wire to a different pin. I'd have to think about it and discuss it with Dustin, since he is the wiring expert here, everything I know is from things he's taught me.

UGHHHH!!! I haven't been able to work on my car for like two months and I need my car!!! if anyone in San Diego or SoCal knows a good mechanic or wants to come and make some cash let me know.... I could probably do it but I have little time and have run out of tools...

someone help him finish it!

LOL YES PLEASE SOMEONE HELP ME!!!!!! FIND ME A GOOD TOYOTA MECHANIC!!!! I WILL PAY!!!!

whats your budget?

I have enough according to what I have been quoted before... Just for shizes and giggles I went to toyota dealership n they wanted 2000 just in labor to start off. I told them they were insane.
