i have a jdm b16 also, im not too sure about that cause my friend did the wiring, theres a tps sensor by the throttle body, and some plugs in back of the manifold, what kind of wiring harness are you using?

 

JDM B16A2 doesnt have the map sensor mounted on the throttle body, it is mounted on the firewall and has a vacum tube running to the throttle body. So you will need the map sensor that mounts to the firewall or use a throttle body with a mapsensor mounted on the throttlebody.

JDM B16A1 and 2 both have map sensor on the firewall

B16A1 has a 58mm throttle body
B16A2 has a 60mm throttle body

Best thing to do is get a throttle body from a B18C engine as this is 62mm and has the mapsensor on the throttle body
