I have a 96 hatch. It had an obd1 vx engine in it. Running a 4 wire o2 on a stock p28.

I have a z6 I am putting in. My evap solenoid plug does connect. My haenss has a 3 wire plug the sensor appears to only need 2. This is the small black sensor on the back driver side of my intake manifold. With 2vacuum lines. 1 to the manifold. And the other to the canister. Do I need this plugged in? The vx didn't have this sonsor at all

Second question. My ECT sensor only has 1 wire on the plug side 2 leads ok the sensor side. This is right next to the vtec solenoid. The factory plug with 1 wire is what I had. But I have a spare plug with 2pigtails on it. I could swap them out and repin the second wire. Or can I just ground the 2cd wire. Or should I just leave it?

Any help would be great! I got everything in and ran into these 2 questions.

EDIT!!!

had a brain fart. the 3 wire plug is my map sensor. (pretty obvious.)

so i guess the 2 questions would be

1. will running no EVAP solenoid be an issue?

2. will a 1 wire ECT plug cause problems?
