1990 Jeep Wrangler YJ Sport with 1994 4.0 Heart

Hello... This is my first post here and I hope it goes as it should! :-)

I have a 1990 Jeep Wrangler YJ Sport and I removed the 4.2 Carborated Engine and put in a 1994 4.0 Fuel Injected engine. It is running nicely, yet I have no dash activity. None of my instruments are working, no Dash lights on when running, Switches work (lights, blinkers, horn, speedometer and odometer) but none of the dash electrical instruments.

Outside of getting a 1994 Dash Wiring Harness, could anyone suggest how to marry the engine harness (1994) to the dash harness (1990)?

Thank you and I do look forward to learning and helping out tons here!
