i swapped a gsr in my 94 civic ex the old motor had vtec already so i used the same ECU harness since the one that came with the gsr was japan for a right side driver it was crisscrossed the plugs were on the opps side does anyone know what I should do to add the IAB wiring (someone told me thats all i need to do since my old motor already had vtec), im not very good at this kind of thing i tried lengthening the ECU wire on the GSR but i plug those up and i dont get any spark changed dizzy and everything still nothing so its a wire in the harness no doubt, im using the P72 ecu
