[scrapper042000]

I installed an evi 75hp ficht tiller for a friend,motor came with wiring harness that's it, no key switch .oil tank etc....almost done but no alarm when key is on and motor off ,I cannot find any connector to plug in the low oil reservoir tank wires to (tan and black ) I have 2 sets of wires with purple,grey,black with eyelets ...and one 8 pin rectangular plug in ,tan/yellow stripe,blue,black,grey,tan/blue ,tan and other tan wires ,alarm is hooked up to the proper connector .

my main concern is that his alarm system is working properly ? I think I will start with a premix fuel tank until I am convinced it is oiling and I see the ficht system returns oil back to the the reservoir that I added
