need a little help here have a obd0 and want to swap to a obd1, do i have to get new wiring harness or will the obd1 plug in , any help would be appreciated

Are you talking about completely converting your entire car from OBD0 to OBD1, or are you just talking solely about the ECU?

You'll need the OBD0 to OBD1 conversion harness nonetheless. If you need the full conversion, just type in OBD0 to OBD1 in google, and you'll find lots of DIYs of this showing the full process.

"the lsvtec" which one? there are 3 different heads you can use and multiple types of internal parts combinations you can use
