just rebuilt my engine and like a noob that i am in the rotary world i didnt label a a pair of wires...

they seem to go to the coils but im no sure....they are connected to the drivers side engine bay or fender wall should i say and they are lengthy enough to go to the colis but im not sure . does any one have or know where i can get good pics of an 85 rx-7 engine bay i mean it's trivial cuz i can just look at someone elses car just by popping their hood and i could see where mine should go...

The + terminal on each coil should have a heavy gauge Black with a white stripe wire with a ring connector. The negative terminal on the trailing coil (towards the front of the car) should have a normal gauge yellow with green stripe wire and a blue female spade connector on the end. The negative terminal on the leading coil should have a normal gauge yellow with blue stripe wire and a white female spade connector on the end.



If the black wires have a green stripe on one and a yellow stripe on the other they connect to the oil level sensor (green stripe) and the oil temperature sensor (yellow stripe). Those are the two sensors on the side of the oil pan. They have two different style end terminals, but they are both female spade connectors.
