wiring mix up

[yungcris09]

So here is my problem i did a plenum pull a few months back and i had to stop working on it for a while. So now im back working on it and have just about everything put back together but these 2 connectors in the back of the plenum are identical i think one is the knock sensor and the other is detonation sensor and i cant figure out which goes where i need help please

VTC connector or California models have one for the EGR or something along those lines

Knock and Det sensors are the same thing and there should only be one. The knock sensor runs out from under the lower intake plenum, there are two vtc connectors that run from two small round components off the ends of the cams, top of the cylinder head (intake cams), The O2 sensors have their respective connectors (cant putz those two). Everything else should be coils, smaller or emissions and I ripped all that out almost a year ago..
