hey i have a question so i decided to go obd1 fro obd2 in my 97 accord with a f20b. which is auto. i pretty sure im going to get a jdm p13 vtec ecu which i belive is from a 93-95 prelude now the guy im gettin the ecu fro he is insisting i need the tcu to go along with it cant i just use the tcu i already have in the car with the p13 ecu and when i do get the ecu of course i need the ecu jumper harness fromm rywire would everything connect right with a obd2 tcu and a obd1 ecu.
