Added the secondary ground strap to the rear of the bell housing, direct to the battery as per the Forum recommendation. Bought a 36 inch eye to eye 4 ga strap and put a wire loom around it. I like to make everything neat and look factory if it isn't. Put the loom on it before you install it as it is a little tricky around the exhaust and heat shield. Pretty cheap insurance for our electrically sensitive toys. Only an hour and that included the coffee break.
