I have just bought a s5 jspec motor and was looking at the wirring. in all the engines that i have bought for other rx7's. this is the first time that i had got one with an ecu with 4 plugs 2 going to the engine harness and 2 that were cut obviously going to the body harness. has anyone out there seen this before cuz i searched and noone has mentioned using it. or has everyone jus used an aspec harness with ecu. if so is there any type of pinout diagram out there for this type of ecu. or am i just assed out a complete harness and ecu.

 

What is the number on the ECU? Post a pic of it.

 

Ill post a pic up as soon as i take pics its in the garage right now so when i get a chance ill deff post one up. It was very confusing when i got it usually when i buy engines with harnesses/ecu they come with a 3plug ecu not 4.
