Help! Electrical Issues On My Nismo
 

Car shut off on me a few days ago, took it to a dealer and they told me the engine harness wasn’t installed properly by previous owner. It shorted the fuses and now I need a new IDPM, immobilizer, and some other things. Here are the part numbers they said needed replacement

28595-1EA0A
24380-79915
24105-JL00A
284B7-1BN6B

Obviously I don’t wanna pay the 4k at the dealership. Does anyone have any idea were I can get these parts for cheaper, as well as anyone who is familiar to this problem.
