I had both, the coyote transducer and the 4.0. Only the plug is different. You can use either one. I used the V6 one as I had the plug to fit it.I plan on using the 4.6 compressor and just wiring accordingly, and using the Coyote transducer switch, I suppose you didn't have that luxury using the 4.6 compressor since your was a 4.0, correct?
How are you planning to use the 4.6 compressor? Will it bolt up to the coyote? Will the stretch belt fit? There is no ac belt adjustment on the 5.0.
