I have 3 s5 engine wiring harness that accedently got thrown torether.

One of them is a turbo harness.

Is their any quick and easy way to tell the differance between the tubo and N/A harness?

if you know only one of the 3 are a turbo harness then just set them side by side and look closely at them and you should be able to pick out the turbo harness from the 2 NA harnesses. other then that ill have a look at the ones i have to see how you can tell..

couple ways.



if the tag is still on it, the turbo is n370 NA is n350



they are basically identical, except the turbo has a knock sensor and a wastegate solenoid. the na has vdi and the 6 ports. the knock sensor is 1 wire, boost control is a blue 2 wire. the vdi and 6 ports just use the same normal solenoids as the rest of the system, so it'll have 2 more for those connectors
