My new project roared to life this morning...now for the detail work. I am lousy at understanding schematics so if someone in simple terms can get me going it would be greatly appreciated. I have the single terminal oil pressure sender(top of block) the harness has the 3 prong that goes above the oil filter which wire do I need? #2 my alt. has a 2 prong(red and brown) can't find where brown went (plug removed entirely and not sure where it was)and are both red wires hooked to hot at all time? #3 I have a water temp sender in driver side of block what color wire would make it work? Thanks for any help.

 

You'll probably need a new oil pressure sensor. As for the others, I'm not sure.

 

Oil sender: tan is sender signal, orange and grey are for the fuel pump switch
Temp sender signal wire is green
Alternator: red wire goes to the terminal closest to the passenger side, brown goes to the right of it facing the engine

 

Best image I could find to help calrify that Red is correct, brown would go where the black is

 

Thanks Joe.I have the wires hooked to the Alt. just checking to see if both red are hot always or key on and don't know where bn wire from alt goes(probably to guage) not sure how to find where it was on harness. Temp and oil working

 

Best I can tell , the brown goes to the volt guage, you're going to have to dig into the engine harness and find it unfortunately
