Hey everyone, I am in search of a good wiring diagram for my 75 K 5 Blazer. I need the color codes from the bulkhead to the engine harness. My rig had a fire under the hood before I owned it and I am having a hard time getting things hooked back up. Thank you all.

Can't see the link aboves information, but they are here too: http://67-72chevytrucks.com/vboard/showpost.php?p=5621043&postcount=1

Don't ever rely on color code on an old vehicle. You can use it as a guide, but need to verify with a voltmeter or eyeball that red wire #5 connects to component 6 in position A of connecter 212.

People (almost always) do stupid crap with electrical over the life of vehicles, it is always good to confirm what the manual says with what you are actually looking at.

Usually I can get the AllData ones also but our account is on hold waiting for it to be paid still.
