3sgte 3rd gen swap problems solved weeeeeee, Finally started Options

[urbandork]

the engine is droped in and i had everything wired up but it wont start or even turn the engine over....

im using the 3 gen 3s wiring harness and connecting it to the connections that are in my 95 5s fuse box.
ihave noticed that there are a few wires that dont plug into anything on that main plug, the one with that platic hold down that pivots to secure the plug in.
the wires on the harness sid that dont connect with anythin on th car/5s side are a green with red and a single silver strip, a solid blue with one silver strip, and a slightly thicker blue with white and a single silver line.

what do these three connect to?

ive also noticed that on the in side if the car that there ar three plugs that are in front of the ecu,betwen the ecu and the shifter assembly, these three plugs are stacked vertically. while the plugs fit some of the wires dont connect to any thing.


sdsfgdvdjfsfjf@!$#!%~!!!!!!!

im going to cry soon ahhhh


what wires do what and which ones do i have to worry about????

Do you not have the ST205 repair manuals? The EWD is in the second volume.

Download them here if you don't have them:

Obviously everything isn't wired up!!

The fact that the motor isn't turning over is probably a separate issue from other things... Make sure your battery is charged and go through your starting circuit to get the motor to crank.

You have to have the wires that go from the plug with the handle in the fuse box to the second sub fuse box that attaches to the radiator. In there, you will find the relays for the intercooler water pump and fuel pump relay. You can start without the intercooler water pump wiring, but not the fuel pump wiring. Did you get a whole clip? If so, those wires are all there and you can add them to the harness in your car.

I've I ever get time (work is crazy right now), I can check all the wires that you are talking about that go to the dash - I have a list of the stuff that didn't match up on my Camry. You shouldn't have to worry too much about the few wires that don't connect under the dash - they are for the gauge cluster boost gauge, cat temp warning light and a couple other things that you don't need.

ill check those out

it would be cool too c what didnt match up let me know asap.... also what else would cause the starter not to turn on? could it be that the ignition control isnt working

im soooooooooooo alfcjal;km

you need to wire in the COR and fuel pump relay, from what i hear. its not all just plug and play.

whats the COR stand for?

and how would i wire them up????

also im still trying to figure out what those three wires do. I traced them back to the ecu and found the pins the the sticky of the wiring diagram is either for a 2nd gen and slightly diff on the 3rd or im messing something up.

the wires again are

green with red line and a silver strip.. i looked at the clip and it looks like its just a simple power line. the car has that color wire on a few things such as the horn so perhaps it needs power so it can open ur a relay?

solid blue with silver strip... leads into the ecu but not sure what it does

blue with white line and sliver stirp... also leads inso the ecu. i tried following the two wires back, the oposite way of the ecu, and found that they just ended and had tabs thingies on the end. it looks like they were hooked up to something but when i got the clip it had been disconnected.

thanks for all the help u guys im really in a bad spot .... im good with the wrench but with electronix im blah.

Sorry, forgot to reconfigure my firewall. Try the link again.

its called the Circuit Opening Rlay. it supplies power to your fuel pump as well as a bunch of other things that let the car start up. you need a copy of the 3rd gen wiring diagrams as well as the 5sfe ones to compare where the gt4 wiring goes vs where the rest of your car wants them to go. the good news is, that its only about 4 wires.

any idea on which ones? what should i be looking for when i look at the diagrams..... electronics + urbandork= "i dont know and im guna cry lol"

[lagos]

well... the first thing you should to is try to find if you have a COR and if you do, then where is it? ive never seen a 3rd gen harness, but i think they put it in the 2nd engine bay fuse box, next to the altinator. once you locate it, take pics of it and all the plugs you dont have hooked up.

Link still isn't working. I also need the repair manual, since I'm gonna have to use it in a few months.

Working fine for me from work and other computers away from home so there must be something wrong on your side... Make sure you can accept connections from port 8080 (the alternate http port)

[urbandork]

can anyone get a pic of what these COR look like so i know what i should be looking for? I looked at the EWD and comapred it to what i have im not seeing n e thing comparable.

The COR is attached to the ECU on the 3rd gen - a 5 or 6 pin relay (5 pins used, 5 or 6 pin plug). Your 5s-fe or 3s-gte one will work if wired correctly. (I'm using the 3s-fe one on my swap - I lost my 3s-gte one!)

[Chanh55]

Like Phatty said, it's attached to the ECU. It's a black relay mounted on the side of the ECU.

[phattyduck]

Yeah, the COR might be plug-n-play on the ST205 into ST204, but the Fuel Pump Relay and Intercooler Water Pump Relay are not. You have to add wires to the harness that goes around the front of the car. This is no problem if you have a clip and can see how they are run on the ST205...

What ever happened to paying me to wire it up for you?!?!

Actually, I'm working to much to have time to do that...

Where is the greeen with red stripe? I remember doing something with this wire, but I don't remember what!

Both the blue wires are fuel pump related - either to the Fuel Pump Relay or something like that. It should be clear on the diagrams (the Euro diagrams you can get on eBay match the JDM ST205 in this area).

-Charlie

[urbandork]

i looked at the clip and i dont see any second fuse box. all ther is are the main box by the bat and the relay box on the other side for the abs , fans and a/c ...... is the second box actually on the radiator? cus whn i got the clip nothing was on the radiator.

[cheeco]

the green/red, and blue/white wires are for the fuel pump relay and the solid blue wire is for the intercooler relay. none of these are necessary to start the car, jump the FP and B+ connectors on the DLC to get fuel and the car will run. if its not turning over then you have another problem. if , at minimun, you plugged all the connectors in, the vehicle should turn over. no other wiring is necessary. the COR relays for the 5s and 3s are the same, as well as the wiring and connectors that go to them. check all the fuses and the starter relay.

also take some pictures of the fuse box and the big grey connector EA1 if you can

Your problem is most likely that you do not have power from the ignition switch to the starter relay. This is your starter signal. It opens the relay that provides power to the starter(starter relay) My guess would be that it has a different pin location on the connector of the 205 and 204 (in the connectors under the center console). See if the starter fuse is getting power. It should be a 7.5a red mini fuse, you should be able to find it in one of your fuse boxes. Dont know where it is because i have a fourth gen. But if there is no power at the starter fuse then it is not getting power from the ignition switch. You will need to connect the appropriate wires together. When you get this problem sorted out, you are going to encounter another bombardment of wiring problems. it may run, but in failsafe mode. Then read the engine codes and troubleshoot the circuits one by one. You desparately need the 205 wiring diagrams, or else you are doomed... If you dont know how to read wiring diagrams, then you should learn, cut your losses now and sell the car, or pay someone to wire the car for you. This is NOT an easy swap. Bolting in the engine is the easiest part.
SOMEONE SEND HIM THE ST205 REPAIR MANUAL!!!!! I know some of you guys have to have it in english..
