90 throttle body and manifold on a 94 wire harness help??

[1GDSMGS]

Ok im rebuilding a motor from scrathc but i was getting part from other cars,anyways i came up on a non-turbo 7 bolt block and a 90 turbo head,but it came with no manifold,so i got a 90 manifold and i got a 94 eclipse wire harness,my car is a 94 eclipse gs and i want to know what i can do about the Idle speed sensor, because i realized i have no TPS on th e throttle body and i have a wire harness from a 94 on a 90 what can i do is there a way i can splice rearrange some wire to make it work please help ive been working on my car for about a yr and im finally finished just this problme im having??or is there a wire diagram i can see?? thanks

90 throttle bodys are a waste of time. Just use a later throttle body and save both the wiring and the problems finding seals when you need to replace them.

so what do u recomend i should do ### i actually got a 93 throttle body.but it doesnt fit ### the tps is hitting the fuel rail??so it doesnt go in all the way what can i doo?

Get a later fuel rail and it won't hit the TPS.

Yea just grab any 91-94 fuel rail turbo or non turbo, and I am using the non turbo throttle body, ridding myself of the throttle body elbow restriction, ( Of course you will need a custom uicp for this ) and some sources say the inlet is like 4mm bigger I believe... ( But I havent confirmed that. )
There are a lot of n/t 4g63s in the junkyard , at least in Tampa, so I think you shouldnt have any trouble finding the rest of the parts you need... I read that your using an n/t block, make sure you picked up a knock sensor for that, and that its threaded for the sensor.

I read that your n/t ... If so that means your converting to turbo right? ( If not you dont have to read the rest of this)
But if you are your going to need to run some wires to make your n/t harness turbo if you were using the same n/t harness.
And youll need to pick up an injector resistor pack, turbo ecu ( from a 91 and up ) unless you want to switch out pins 6 and 14 ( what im about to have to do to intall this 90 eprom ecu ) and wire in the turbo mass air sensor because it has a 7th wire. Mavisky made a thread on this. Sorry if that was irrelevant I just figured if your taking the money and time to build a motor up like that youd be going turbo. Ok good luck.

thanks u guys, that info really helped me my car still not running do to the fact that i mysteriuosly need a new battery , but i was able to set up the fuel rail,as for the knock sensor i saw the whole were it goes so all i have to do is thread it,im not going turbo just yet its planned for later im just going n/a for now but thanks for the tips and its well appriciated
