1999 ranger 2.5l diagram?

[nate_m]

hello everyone, my 99 ranger, 2wd 2.5l 5speed failed inspection because the readyness monitors are off. i hooked up an obd2 code reader and got some to reset, BUT, when i shut the truck off i loose power to the computer and everything resets... so, does anybody have an evtm that can send me a picture or somthing of the computer pinout? i gotta find the constant power wire to it and test it to see if it's got power, if not, follow it back and find out wtf is going on. if i keep failing inspection, i'll start getting tickets for failure to repair vehicle (happened before)

thanks guys,
-nate

well thanks to a friend at a shop, he hooked me up with some diagrams. turns out if you want to know the memory constant power wire for the pcm is yellow. followed it down to the power distribution box where i found it had been worn threw by a sharp edge. (fyi there is a TSB about any wire being broken there due to rubbing on a sharp edg under the power distribution box) anyway..., that's hopefully the problem. fixed that, we'll see how it goes now.
