hello. i recently bought a greddy turbo timer and i need to locate the speedometer wire to tap into. i havnt located the ecu but i located a box under the steering column that says integreted unit on it. i found on another website that the speedometer wire is the green and yellow wire on the ecu plug. there is a green yellow wire on the integrated unit plug. i just dont know if it is the right one. i took apart the passenger side dash and dont see an ecu. any help is greatly appreciated. thx guys!
