RB25 wiring questions-what are these plugs, etc.

[SR20DETGUY08]

Im doing an RB25 swap in my 97 s14. I dont know what these plugs are for though. Hoping one of you could help me.

As far as the TPS goes, I have a S2 motor but somehow I was told I have an S1 TPS? Can I run this TPS or do I need to buy one for an S2? Also, what is the large grey plug by the tps in the pic? Something for Cruise control or something? As far as the other 2 plugs...I just dont know what they go to. And the wires I showed also, I dont know what they are supposed to go to. Any/all help is appreciated!

bump need help

Looking at the end of the plugs doesn't help much. We need to know where on the harness those plugs are located and then what color the wires are at the plug. They are all on the engine harness right? Or are you asking about body harness stuff too?

I don't know WTF that brown plug is by the TPS. Looks like one that goes on a coilpack...

Darius, it looks just like my S2 TPS harness. Mine has a brown and gray plug just like that.

ohhh that's why it doesn't match up with the S1 throttle body and TPS. Makes sense now.

haha yeah i knew that...its an s2 motor but somehow an s1 tps got thrown on it??? But do any of you guys know what that large grey plug is under it?

[fast_s14]

is that large gray plug located near the front of the motor next to the intake mani?

[fast_s14]

My car is at work so i cant go look but i think the fuel injector harness plugs into that plug??

[SR20DETGUY08]

no its actually attached to the TB. The injector harness is already plugged in where it should be.

[fast_s14]

main harness is suppose to plug in there. save yourself time and get a s2 throttle body

a mid 90's maxima tps should fit...
