On the clucth fan could i just hook it up to the 2 wires already coming out of the cab from my fan switch i have. With me being heavy i normally just let the fan run espesially with all the mountians i pull.

Thanks Dave for my engine temp and oil pressure could i just tie in to the wiring before the sensors and just a run a wiring into the cab to the temp gauge and the oil gauge after 4 hours of tracing and checking wiring all im waiting on is the new TPS and checking to see if i could just splice into the wiring before the sensors cause i cant seem to find pin on the out going to the cab for the oil pressure and engine temp.
Thanks in advance for all the help you have given me

Thanks for the schematics Dave i need to pick you brain a little on my truck the oil pressure was done with a regular gauge is it still done on the 3406 e or is it electronic if it is electronic you wouldnt happen to know what pins they are
also coolant temp what pins are used on the 3406e. Everything else ive figured out im hoping with this info i can have it back running by the weekend. Also on the peec it only had a 2 stage jake is the 3406E a 2 stage or is it 3 stage if it is a 3 stage can i just get away with low and high jake setting cause i really only use the high side cause im never under 4500o with this truck.
Thanks in advance

I have been beating my head against the wall im trying to find a pin designation for the ecm on the 3406e so that I can take my 2 harness from my cab and make them work into one. I've talked to my local cat dealer and they keep giving me the run around like they don't want to help. It took them 2 weeks to realize they had the harness I needed no im at the point of needing a wiring diagram so that I can make the harnesses work. All im looking for is a little wiring diagram of both motors the local cat dealer has me at the point of just selling the truck and buying a Mack so that all my fleet are the same
any help with this will be greatly appreciated
Thanks Mike stotler
