Added the fittings and brackets to the oil cooler. Ran the oil lines from the oil tank to the cooler, cooler to oil pump, two bottom returns to oil tank. As others have noticed there was some residual oil that drains out when removing the lower plugs so I was ready with a funnel. The left side plug is better to open first as the oil will drain out of that side that has much more access for a funnel than the right side.
