I know they have lots of these out there on how to make this run on my stock harness by swapping over my old parts 99 Civic SI (injectors, alternator, manifold,oil pump, vtec solenoid and distributor)

My concern is minor things such as the Thermo Fan switch on the back of the JDM B16a block obd0.

1. Will the thermo housing on the usdm fit on the jdm and the on/off function for the fan work?

2. Do i need to fabricate my harness to reach the back of the block

Also do the stock jdm oil pressure sensor(back of block), ect and temp senders(side f cylinder head) plug n play with usdm harness

Thank you for reading will truly appreciate the advice
