I am using a 99-00 civic EX harness on my 00 b20z usdm longblock. I already swaped it into my 00 si and im almost ready to go. I have a couple of extra plugs unpluged and would like some info on where they go.

-So far my power steering hose needs a 2 wire round plug and the nearest plug is the knock sensor plug which is 1 wire and also round.

-My IAT is not plugged as well. I'm using a Ls intake manifold and im not sure weather to extend/change the plug to use the Ls IAT or buy a civic IAT and poke a hole into my stock b20 intake elbow.

-I am using a obd1 p75 and was told I dont need the knock sensor or crank angle sensor

need some help please

helllllllp

 

 

up to you on the iat...whichever is fine (i swapped connectors on mine)
p75 does not check for knock or crank angle, no

"power hose needs a 2 wire plug" ?????

 

Hey thanks for responding. When you swapped the IAT plugs, which color wire did you position for the left/right pin on the IAT sensor?

Also I meant *power steering hose* sorry for the typo. The power steering hose running from the rack has a green male plug fitted with 2 pins inserted. I cant seem to figure out which plug i'm supposed use there. Any clue on the wire colors for that plug?

 

I heard some people just let it hang. Since you are using a obd1 I don't think it'll look for the IAT sensor. Don't quote me on it though.

It WILL look for the IAT. I just extend the wires and run an obd1 plug to the IAT on the intake mani.

 

The IAT would show a cel if it wasnt plugged in. It happened when I used a obd1 p72 with a 00 gsr swap in my previous Ek.

 

I think i'll extend the wires and swap the plugs but I dont know how to position the wires accordingly to the sensor.

 

why not use the stock ecu obd2 b20. p75 what for?

 

im sorry the p75 is the correct ecu. it is obd2

 

Im actually using obd1 p75 with a jumper harness

 

swap the two intake sensors. they will cause the motor to boge out if they are reversed

 

Swap which two intake sensors?

 

the two that are the same hook up on the throtle body

 

One is an TPS and one is a MAP sensor. I dont think you were asking about that though.

 

I definitely dont want my motor to have problems, can you be more specific? I'm trying to picture which 2 sensors you're talking about but I dont have a clue.

Also, anyone know which plug to extend or swap out for my power steering hose.

 

By swapping the TPS and MAP sensor, do you guys mean to relocate? I wasnt aware the 2 sensors needed to be relocated

 

maybe im just confusing you. is your swap obd2? does your motor run?

 

I have a usdm 2000 b20z motor and I havent started it up since I purchased it from the yard.

*Also, I believe the swap is a obd2b*

*Also, I'm using a obd1 Ls intake manifold*

 

if you havent started yet then disregared my post's

 

Im going to try starting it up tomorrow, im feeling a little lazy cause of the cold weather

I still need to figure out the wiring for the IAT and the power steering hose plug

 

holy crap so many peple not knowing what theyre talking about....

I'll get you which pin is which color for the iat later today.
Same for the power steering connector

 

ok, on the iat connector, the bottom pin is yellow, top is black

on the power steering, the wires are green and black
(sorry, i dont remember which is which, its freezing out now and snowing like crazy)

Thanks for the help

I'll figure out the positioning of the PS wires through trail an error. If by any chance the positioning is incorrect, should I expect a check engine light or would the power steering feel heavy?
