After figuring out the wiring with some help, I realized there is alot of redundant power supply between the e30 chassis and e36 s50 wiring harness. So after eliminating this redundancy, I was able to get all the grounds correct, get all the power correct and turn the engine over for the first time, which is a huge load off. Now I need to figure out only one more connector, put the intake on, put in the oil and oil filter, serpentine belt, and radiator.
