"Does your 40 have electr1c sh

"Does your 40 have electr1c shift or mechanical?

The colors on the 70 are as follows:
Red = <font color=""ff0000"">B(+)</font>
Blk = B (-)
Purple = <font color=""aa00aa"">Switched ignition</font>
Blk/Yellow = Mag. <font color=""ff6000"">kill</font>
Gray = <font color=""808080"">Tachometer signal</font>
Purple/White = <font color=""aa00aa"">Electric choke</font>
Yellow/Red = <font color=""ff6000"">Start</font> <font color=""ff0000"">Circuit</font>
Tan = Engine alarm


What of these wires are on your 40 will depend on what model you have. Colors will match, but you may not have electric choke or overheat wire.You may have blue and green shift wires. If this is the case, this control will not work. You need a control specifically for the later model electric shift system. '72 was the last year that system was used.

Good luck
