Putting JDM engine in!!! :D

[89suprat]

hey so i've had a jdm engine installed by a motor shop here in ottawa and i have some interesting questions, first of the car is a 89(newer style) but the engine that i acquired is from a 91 auto jdm, now it's been running fine until i decided to check up on my vacuum lines, for sum reason my bvsv(whatever that is) is not on my thermostat housing but rather an electronical device is in it's place? all pictures i have ever seen indicate there should be some vacuum lines there, the company custom build a wiring harness for me as it was chopped near the block. but i still have the 89 ecu in the car and as mentioned you guys were talking about the different impedence injectors on each model, is there anyway i can check if my setup is ok. thanks for your time
