I replaced my stock motor with a new one. I have a Accell distributer, no external coil, and a new high output starter. The starter has BATT, MOTOR, and SWITCH terminals. Assuming the BATT is the direct to battery positive and the SWITCH is the purple wire from yhe ignition switch what is the MOTOR? The starter instructions says that because there is no coil the R terminal of old is not used. Any help, we have replaced the engine harness.
