help with wiring to sensor junction box please

after replacing my crankcase vent value and DISA o ring repair, I am having trouble with the sensors that connect to the harness in front of the throttle body. I was under the impression that all the connectors where keyed differently and would only fit in the right socket.

I think I confused the oil pressure / level switch with the EVAP unit and maybe more.

I now have a p0340 code and no oil light (bulb works fine on both colours in test mode)

does anyone know of a diagram of the connection block and the routing of the wires, I have tried google and realoem but not very much info.

thanks in advance

The WDS is the best resource for diagrams.

Hope it works for you. I had to jump through hoops to get it to work on my old pc. Installed virtualbox and free ubuntu with firefox and an old java plugin (think 6) to make it work. java took the most time to navigate their website for the older versions. took like 2 hours to get everything together and running. If i had it on my new pc i would just look it up for you. if you do use the WDS make sure you are searching under the right DME and production dates are located near vin on your driver car door. Good luck it is totally worth the time!

as far as the routing of the wires you will have to follow the harness to where it leads.

Under my hood all the connectors are keyed and how far they reach also helps determine where they go. There may be two or more keyed the same, but i doubt they would reach the wrong socket with the same key, if there even is another with the same pattern.

Anyways, did you figure this out?
