c20xe loom

[gaz w]

i've recently bought a c20xe to go in ny nova, it's a dizzy type engine and it came with 2 engine looms, the loom that is on the engine has no lambada sensor on it and the other loom has, can anyone tell me which loom is the right loom for my engine.
the ecu code is 90 410 501 GX i think the engine is out of a cav gsi if thats any help

thanks
