Merc V-8 Engine Modules Wiring - help!!
 

Mercury has 2 modules on the distributor I have and am retro fitting to a 350. One has 8 pins and the other has 5 pins. I have been able to trace what each pin connection colour is and what every wire connects to on the engine except for the blue wire that come off the 5 pin module. Can anyone tell me what this blue wire is connected to within the wire harness.
