I have a manual EG and changed motor to d15b double vtec with automatic box p2j j61. I have eliminated all CELs and the vtec still doesn't engage. It will only run to about 2500 rpm then it will go on limp mode. There is an article online that said that since the ecu is automatic, it thinks that it is in neutral. It will start but it won't vtec so I needed to switch it to drive to have the vtec engaged. Please help with the wire colors needed to have it switched to drive from neutral or park

this is the article that I was able to find:
