Doing the auto to manual swap stuck on the wiring. Wondering if there’s a way I can save myself money. I have the ecu and harness for both vehicles. My 2000 Ex auto ecu, harness and the 98’ manual ecu and harness. I know the plug connectors are different but is there a way to run it without buying a jumper harness?

 

NO... well yes actually, but certainly not easily. You would have to be a wiring genius, possess a 2000 Civic FSM and a 1998 Civic FSM, and a pile of pins, wires, clips and ECU plugs to convert the wiring in your chassis.

OR, you can just buy the damn conversion harness adapter. I suggest you save yourself a ton of time and heart ache and buy the conversion harness adapter.

 

Yes, by building your own jumper harness or repinning connectors. The End.
