My right coil that powers cylinder 1&4 is working fine, but cylinder 2&3 are not firing, I can't pull the plugs just yet to check for spark because I don't have the tools, but I used a multimeter on the leads, I could only get a split second reading cuz it would only work while the starter is engaged. Coil for 1/4 got around 12v while coil for 2&3 was getting under ten. My question is, where do the wires run thru? I want to know where each one goes so I don't have to rip apart the harness and follow the wires
