I was wondering if anyone has or knows of a diagram of the wires of the oil pressure switch on a 2.8l tbi engine the ones on my blazer kinda burned up in a place i cant get to repair so i would like to clip it at the relay and just run some new wires but not sure what wires they are i tryed to follow the wires but they run behind the engine..

 

My references do not have the greatest of detail... See if this helps (attached):

 

so im guessing i would cut the Tan white wire from the relay and from the plug right? cuse when it was melted it was blowing the ecmb fuse but not sure what other one i would cut cuse the plug only has 2 wires running to it but cant see if they split off behind the engine in the morning ill try and get some pics of the plug and the relay and thanks for the reply
