99 breeze engine wiring harness, no spark

hey i have a 2.4 breeze.... it died one day... it was really hot that day. and i was over heating i think. but i took it to the shop and they said it was in the engine wiring harness. they said the wires melted together or some what. the head wasnt getting and spark either. so it was the signal wire that goes to the crank shaft and cam shaft positon sensor and coil pack...... does any one have a engine wiring harness for sale? please help me!!!!
