NO FI light, bad power to ECU and relay

My bike decided not to start a few weeks ago. When ignition key was turned on the oil pressure light would come on but no FI light and neither fuel pump or exhaust valve/solenoid would cycle. Bike would crank over but no fuel no spark. No blown fuses and the usual suspects (vehicle down sensor etc.) all checked out fine. After some initial troubleshooting (and stumbling) found the issue after obtaining some electrical prints. The issue was a voltage drop due to a corroded/burnt connection inside the wiring harness at joint connector #4. The associated ECU relay on the relay board had poor continuity across it's normally closed connection as well (5 ohm resistance). All other relays and their coils checked per spec. Found a replacement NEC EQ1-11111S relay on Ebay to replace the questionable one on relay board but have not found a source for the joint connector plug style and bridge jumpers. Does anyone know where to by the joint connector components, the one on my bike does not look to be salvageable and I would rather keep it in it's stock configuration and not make up improvised wiring connections.

Thanks in advance for your helpful replies.

To get helpful replies you might want to put at least what year the bike is.
Heh, yes that would probably be helpful. It is a 2004. I am sorry I thought I had posted this in the Gen 1 forum.
