its a 91 ls 5spd, i dont have a multimeter, and on my distributor wich blue wire there is a blue wire on the top of it next to another wire i do belive to be black and yellow and then the only other wires that ive seen that come off it its kinda in between the top and back side of the distributor but thats a plug... and i want to keep it looking clean so wiring from the insde would be the best but i can get from under the hood, just need to be sure
