3GENJDM: Did GEN 3 swap on 93t chasis, no Power steering, help please

[tksmr2]

Hello,


I recently had my 93t's engine replaced for a 98 GEN 3 engine.


Now, I don't have power steering. Any ideas as to why?


Also, I know Ty Saxson from TCS Motorsports did the same swap into his
93t, and doesnt' have power steering either.


I'm using the 98 engine harness/ECU, and the 93t body harness. I was told that I could use the 93t body harness b/c the 93+ cars were pretty much plug and play with the GEN3 harness.


I'm sure someone has run into this problem. Didn't Brian Hill swap a GEN3 into his 93t? Maybe he didnt' have power steering though.


Thanks!

Power steering is for sissies. Sorry, had to say it hope you find out what's wrong with your car.

Does your gen3 body harness have a power steering relay? It looks like it's normally located in the engine bay fusebox for some reason. If your gen3 body harness came from a car without power steering, this relay (and possibly supporting wiring) won't be there.

I find with these swaps, it's easier to modify the engine harness, and simply repin the 22pin ecu plug on the body harness.

wow.. ok.. I think we may have something here. The power steering relay and most of the associate power steering stuff is in the frunk. I kept the 93t body harness, but of course used the 98 GEN 3 engine harness, and ECU to the engine fuse box.


I'm trying to find out if my clip was originally equiped with power steering. I'm also going to take a look at my spare 98 body harness to see if there is anything on there that looks like it's related to power steering.


I don't even know were to repin.. b/c I'm not sure if the ECU just doesnt have power steering wires coming out of it, or not. I'm guessing it does not, and that I need to repin in order to get it to work.

thanks!

well.. I actually really like it.. and w/o it.. it's a pain. I don't mind not having it in my MK1.. actually like it w/o power steering for my MK1.. But,the MK2 is another story.. it's so nice in the MK2. Plus, I think there is a difference b/t a car w/o power steering that doesn't have power steering equipment, and a car that is w/o power steering and has power steering equipment. The car was not designed not to have it, making it even tougher to deal with.


I need to get this fixed ASAP.

theres 2 pin in the ecu for the PSCT and PS thats connected to the ecu. that as far as i know is hooked up. did you also hook up the speedo sensor?

Not sure.. will look asap.

I heard the steering racks are different for cars with power steering compared to those without. An MKII without power steering is actually nice. Instead of bothering with all the wires, I would convert to a non power steering rack and it would be even better.

ah.. no way.. Its like trying to make a 10 point turn getting into my garage right now.

[David]

That's because you have a power steering rack with out the pump actually working. So get a non power steering rack, and it will feel lighter.

[tksmr2]

I have to swap some pins on the ECU. I found out from another source.


Thanks everyone. I"ll be back if I still have trouble.

shoulda merged the harnesses instead of using the JDM body harness.

[mr2_kevin]

i had this problem except im using a 91t engine body harness..just had to repin some wires and thats it...easy as that

I did use the USDM 93t harness with the 98 GEN 3 engine harness.

yea.. if I wanted to do that.. and spend more money.. but I don't, and I was able to switch some pins on the ECU.. now it works.

[mr.ac]

good to hear. this was the first time I've read the power steering fail with a swap. but then again I had my wiring sent out, so I never had to worry about it.

[stewart]

Mr ac where did you send your harn. to

[tzr250rg]

need some help. i hust swapped gen3 into my 91t- and i do not hav any spark.
using;
91t body harness
94+ engine harness
97 celica /ecu 89661-2B840 - i was told its equivalent to the mr2 gen3 ecu.
I repinned and spliced EA1 harness. as per MR2 MOD PROJECT

Any

I have a 98 body harness for sale if you end up wanting to go that route. Otherwise, I'm not sure as I have a 93t chasis.

[tzr250rg]

thanks for the offer however, i don't think there is anything wrong with the body harness. i'm getting 12v at the IGN relay just nut at the coil. I'm getting 5 volts at the igniter.

does anyone know how to test the relay? or any advise?


thanks
