Help with my aveneir swap in my 02 sport.
Picked up my motor recently to install in my 02 sport G20 om swapping in a 99 g20 harness.
I was looking at my motor and saw these hanging there just wondering what they are, they seem to run off vacuum.






Also I've been going through some threads Byt can't seem to find info about the transmission harness. The ENGINE harness I have Is off of an automatic 99 p11 which has a large clip that would normally connect to the automatic transmission harness. But my 02 harness doesn't have a large plug, it seems to just run through the harness straight to the ecu. Can I hardwire this into the big plus from the 99 harness or am I better off finding a 99 g20 manual transmission harness?

Thanks for your help in advance.

1st pic is part of the throttlebody heater and also I think the other half is in the second pic with the blue tape?

2nd an 3rd pic is AIV control solenoid

An yes I believe your need a manual harness.

Source a 95-96-97 manual harness/ecuobd2 or if your state allows stepdown to obd1.make sure you have disributor n maf from corresponding year of electtric controls

Do I need these? I don't think the 99 harness essential harms these connectors whatsoever.

I don't think you need it, but you should put it in if you can. Will help with your idle in relation to cold/hot weather.

Does the black bracket just run water through something? I don't see an open water Inlet anywhere for it. And the other one runs off of the bottom of the manifold but what would that run to obviously something vacuum dependent.

u don't need the heater.

deff hook up the air valve.
should be a plug in the harness for it

search over on G20net there should be some good swap info

look at the throttle body, theres a port on each side of the bottom, hoses run from them to the big water pipe under the manifold..


this is where the throttle body heater shit runs to on a DE, if i remember right the det is the same... we deleted the throttle heater lines an used them for coolant for the turbo instead.



if you could provide some better pics of the underside of the manifold i could probably point out where the other hoses hook up for the AIV solenoid..

Why not just repin your 32 bit harness to OBD2/1? Easy peasy

Proper name for that guy is IACV - Air Regulator, you don't need it. When cold it opens a door that sends a ton of air to the manifold, this device is what keeps your car idling at 1500+ rpm for 90 seconds. I haven't ran one on my P11 or B15 and never had an issue, without it the car idles at exactly the RPM you set in the tune, which is much better control.

You don't even have to go that far for swap information. Both of my cars where 32 bit and now are OBD1 swapped with plenty of pictures and details of the swaps.
