Can anyone tell me what these wires go to? I got my engine in and every thing on the motor hooked up but I have extra wires in the engine bay and I can't seem to figure out what they go to. The first to are are right next to the computer. The boxy one has 4 wires, red/blue/black/green.
The next one has 2 wires green and black. And the last one is on the pass side comes out of the same spot as the horn wire and it looks like brown with a white stripe. Thanks

 

Green and black one is for your electric fan I believe. Not sure about the others though

 

Thank you

 

the other port next to the pcm is the obd1 connector
