[COLOR=crimson]New in the Forum and to the rotary.
Need Help getting a wiring diagram for the B20TT I purchased from Japan. I have not been able to find out from the seller anything about the vehicle. I believe it to be a 89, but not sure. It has an automatic transmission attached to it. I am looking to use this in a car to run hill climbs. Therefore any helpful tips on upgrading it would be appreciated.

 

do you mean a 20btt a three rotor. you should got to the 20b section of the forum just go into rotary performance and you will see it
