That's a good point. I suppose my Sea Rays were and are older and did not have an EIM. Might someone be able to refer to the wiring diagrams in the owners manual to track down the appropriate wire colors?I'd suggest caution and hold off on that. The tabs on the 280 run through the port helm switch pad and Aft EIM module. As a result any electrical tests should be conducted with a measure of caution. The only place the wiring color codes for the the tab system will match the instructions for a pure Bennett system are at the connection to the pump. As I recall the wires coming off of the EIM do not match the Bennett colors.
