question on fox headlight/alt harness applications

[PSPstang]

my question is....is a late 92 V8 headlight/alt harness the same as a 1991 V8 headlight/alt harness??

i was told 90 up are all the same, but want to check to be sure.

[INSANELY CRAZY]

90 stands by itself,(the headlight may be the same but the dash/engine harness are not) 91-93 are the same though

[PSPstang]

i know about the difference with the engine/dash harness due to the fuel pump relay location. just want to make sure the 91 and late 92 headlight/alt harness are compatible and same to use!
