I purchased a new tack for my boat and it never had one installed from the factory. I was told there is a wire I need to move under the engine cowling. The yellow/gray wire is to be moved to the pole conating the gray wire . Is this correct. My motor is a 1994 90hp evinrude. I also purchased the correct wiring harness for the tack. At the present time there is a plug in below the key switch containing only one wire. The new one has three wires which are black,gray and purple. On the back of the tack there is a place for the ground,12volts and the signal wire. Could you please inform me where I put the wires the purple,gray and the black ones. Thanks in advance folks.
