vtec f22b1/POH-L01

Ok so im waiting for my ecu to come in threw the mail and Im really getting frustrated on how im supposed to do the wireing on this vtec. From what i understand. Solonoid wire goes into a8. And i have no oilpressure switch just the factory bolt. Idk if i need to bypass this creat a jumper or what. Ive seen a lot of post about this. But non about using the poh ecu and what to do. Currently car runs like ****. And ive had a full tune up on the car. Just need vtec for this motor to run properly. Im not trying to build a race car. I just want my car running right with the stock hardware. Im really close to being done with her this is littarly the last thing.

Current ecu. 37820-P0J-L01

I also need to know if i bought the right ecu.'
My car is a 5 speed.

37820-POH-L01.

I can answer any question and all help is appreciated.

OBD2 Connectors, view from wire side

Wire colours around the VTEC pin;
A1 is YEL
A2 is BLU
A3 is RED
A4 is BRN
A5 is ORG/BLU or ORG/BLK
A6 is ORG/BLK
A7 is empty
A8 is GRN/YEL VTEC Solenoid............
A9 is BRN/BLK

However if you are adding VTEC to a non VTEC Accord. I don't think the GRN/YEL VTEC wire will be in the ECU wire harness.... Unless you replaced it.

That pin is one of the smaller ones. I have always just reused old harness connectors with 2-3" of wire on them and spliced/soldered them to new wire. I have never taken the time to try and find the correct part number for new ones as I usually have a few spare full length ECU harness wires laying around.
