hey guys just had a quick question. i have a 96 civic ex m/t w/o abs.was gonna be my project car but just bought a 09 si which im going to put my time and money into now. i was looking to do a jdm d15 off hmotorsonline into my 96 daily and was just making sure that i can use my stock harness. im pretty sure i can cuz i have the wires for vtec but was just wondering if there is anything that i would have to do or is it just a r&r situation. also gettin a hydro tranny from them as well so i dont have a low mileage motor with a high mileage tranny.
thanks guys any input would be great!
