im new to the toyota world, so this maybe a stupid question to some of you .... but can the 7m engine harness be used with the 1jz motor? what are their differences, considering the 1jz is jdm rhd so using the 7m harness would eliminate the hassle of fitting the 1jz harness in the car. ... i searched the topic and i see that everyone that were doing 1jz's were drilling for the 1jz harness.
