New Toyota Engine Bay harness is 100% OEM for either OBD1 or 2 Auto or 6 Speed. This is the MAIN Engine wiring harness in the Supra's engine bay and gets you everything new, clean. You can get rid of the old 15 year old heat soaked brittle harness with all the broken clips in exchange for something that will clean up the rats nest that might be in your engine bay from another shop. These are worth every penny and is a must when and if you are pulling the motor out for an overhaul!!
