On a OBD2 car (98 Integra) is there any wiring that has to be done for the swap? I know there is a Vtec solenoid and was wondering about wiring for it.

 

obd2 to obd1 adapter / wire in vtec if your chassis did not come with vtec

 

A little in more english please. The ECU I got with Hondata came with a OBD2 to OBD1 adapter, I THINK. (I know it came with some type of OBD to OBD adapter) But I was more wondering about the hooking up the under hood Vtec sensors.

 

in that case you will need to wire in vtec sensor to ECU depending on what your chasis is set up for - theres more then one integra model so some are already wired from factory and others are not (google is your friend)

I googled the **** out of this very topic and found droves of information. It is there. My civic was originally non-VTEC, and Google provided information on how to do this as well as which models were pre-wired VTEC, even without..
Given I had to do this from the ground up, it is a simple and easy process. Hell.. I did it. Lol! You can find information on non-VTEC to VTEC in my build thread alone. It was archaic at first but I have since ironed out the wrinkles and made it smoother. Lol.
