Trying to figure out the proper way of doing this wiring. Just need guidance.
I dont have money for blox/ s2 manifold at the moment.

specs :
93 civic cx
OBD 2 b18c1
OBD 2 gsr harness
OBD 1 p72 ecu

1.I've been reading, and i know im supposed to switch A20 (evap) to A17 (iab), give the black wire a 12v source. Where is this black wire located?
My IAB wire is red/blue
evap is red/ grey spots.

2. When i install pin A20 into A17 spot, do i switch the pin A17 into A20 spot as well, or leave hanging.?

3. Found this picture, is this a right way of doing this? Do i soder an opening together to the Ground source? or cut the red/blue wire in half and just ground it to black/yellow wire?

Move A20 to A17, A17 will previously have been empty, unplug the evap purge connector from the purge solenoid and plug it into the IAB solenoid, done.

For some reason i had no pins in A20 or A17, my evap pin was shifted one over.

1.I put pin A20 to A17.
2.Unpluged the hose for the UFO looking thing. Purge Solenoid Valve.
3.Unplugged one of the hoses in the IAB solenoid, Where the One hose connects from Plug to solenoid. (does the loop) i disconnected that hose.
4.plugged in the hose from the Purge Solenoid Valve into that hole.


If this is right, wrong, let me know what hose i should be disconnecting on the IAB solenoid. I put a screw in the plug that i took off.

From KS to IAB. You'll get it done. What are you unplugging? Do what 94EG8 says.

Lol I'm trying, I did what eg said to do, but my idle was weird, started my car, idle went to 2000rpm, revs the motor went to 2100 rpm a kept going around that rpm 2100- 2400 rpm. Only when I pushed the gas kept rising but then drop backto 2100ish area.

I'll keep fiddling around with it; hard to get my hand under the throttle to pull out hoses tho , but see what I can do tomorrow:

You have an major air leak. Sounds like your fpr is unplugged. Plug up all vacuum hoses and don't unplug anything from the intake manifold. Report back.

I'll try to clean out he iavc, and check if any hoses are in wrong. Spots

Noticing on the evap, I don't have the Middle hose going anywhere, and it doesn't seem like it's sucking air ither, and I don't have a hose connecting to my throttle body near the air intake hole. I'll keep u posted tomorrow afternoon tho,

Also i'm thinking it might be caused by my TPS sensor, i tried to remove once, but one of the bolts broke on the throttle body, so i just screwed the other one back in, it might need to be calibrated since it was moved around trying to undo the other screw.....
