according to the visual on the commander 2000 , there should be a tan wire with a blue stripe ? my harness is just a plain tan wire. could this be it?things are getting closer but not quite there yet. i have it hooked to the tan wire , i have a continuous audible beep beep beep etc. i checked maybe the oil tank float , but that is new also.tank is low on oil but i pulled the cap and raised the float by hand and there was on change in the beep. i not at the point of starting the engine yet , but i am testing each step i make in the process. also i cant seem to find the tach wire in the harness from the engine . is it a grey wire? as this is the only wire i have left that isnt being used.


thanks in advance as you guys are saving my bacon on this build with your advise.

beep beep beep is the warning for low oil. Check you oil tank or bypass that sensor for you testing.
