HiCustomer

Thank you for asking your question on Just Answer.

The relay is mounted on the passenger side inner fender and is held on with 2 8mm bolts. There is a battery side post and a starter side post. On the battery side post there are some smaller extra fuse link wires which mount on the battery positive cable side with the positive battery cable. The other large post goes to the starter cable. Then there is one small wire (red/blue) which is the crank signel wire from the key which goes on the small pin on the front of the solenoid.
