280C Wiring Diagrams??

Hey Guys,

I'm trying to correct some foolishness that the PO did to the wiring on my 1973 280C. My FSM only goes up to 73 and my car obviously has some wiring that didn't make it into the manual in 73. Does anyone have a 1974 wiring diagram that I could compare with?

One of my biggest questions: there's 3 double-fuse blocks on passenger side of the firewall. One is for the AC. Can anyone tell me where the other 2 lead to? Wire colors would be a big help too; a couple of the fuses are blown bad and I want to know what systems to check.

Thanks!

Thanks Mike. Hmmm... All four windows work & I have blown fuses. Any chance you can provide wire color/where they go?

Thanks!

My '74 280C has manual windows so I can't help you there. How about the "overheat" or auxiliary cooling fan? Does it work when you ground the sender? Does the car have a sun roof? Does the rear defroster work?

No sunroof. Not sure if it has a rear defroster.

I know one of the blown fuses is btw the blower motor & the AC pump (that's the one fuse block I have completely mapped out). The other 2 I'm totally clueless on. I think that one of those is for the Aux fan, but that's still only one of the 2 fuses in that block.

Anyone have a 74 wiring diagram? Bueller... Bueller...
