On a turbo car the wires for the alt come off the ENGINE harness on the left side of the engine bay.

OIL and WATER come off the EM harness (on the engine) on both non turbo and turbo cars.

The non turbo EM harness on a Turbo car causes water to not work plus several other items to not work right/atall.

I'm still lost. Turbo car/chassis.............and using a non turbo engine WITH non turbo EM harness on the engine and this non turbo EM harness is connected to the ECU AND the FRONT harness. What part of this is right and which part is wrong of what I just wrote??????

Non Turbo EM harness mated to a TURBO front harness will case all sort of irregularities. It is not the connection of the non turbo EM harness to the ECU that is corrupt, but the connection of the non turbo EM harness to the TURBO FRONT hanress that is bad/corrupt.

This connection of the EM harness to the FRONT harness is thru two ORANGE in color plugs in the passengers foot well.

You say the ENGINE harness on the left side of the car is missing and you installed just what in its place???? That would be the harness on the turbo car that has the two wire plug for the alternator. Called the ENGINE harness. Has the CAS wiring also plus various other items on that engine harness.
