hello all, im wanting to convert my dads 68 cougar from points to electronic ignition. we just bought a new motor out of a 77 ford F250 that had the electronic ignition so i dont have to convert the distributor. my question is this, i went to zone and bought an ignition control module for a 77 ford F250. the harness on the engine plugs into the box perfectly but there is another 2 prong plug on the box that im not sure about, im not sure how to rewire the cars original ignition wireing to the new box wireing. the cars wireing system has 3 different wires running into a plug just outside the firewall that then ran to the oil pressure, coolent temp, and coil. well on the new engine, the harness plugs into all those and thats the plug the fits correctly into the new ignition module, but the other connector that i figure go into the cars wireing is only 2 wires, red and white. since the cars wireing has 3 wires im lost. help!!!! this is the only thing stopping me from getting this car running.
this is the box i got
