Hello All,

Last year I bought a 71 Mach 1 that needed to be brought back from the near dead.  I've got the engine and trans out right now as I work on getting the engine compartment cleaned up and everything out so I can repaint the engine bay.  While I'm waiting for that to get finished I'd like to do some light testing of electrical components in the interior such as dash lights, radio, etc.  

Since I don't have ANY wiring in the engine compartment is there a way I bring 12 volt power temporarily into the interior to start working in there?

Thanks!

Scott

Making some progress...



 
If you have the harness that goes into the back of the fuse block, I believe the solid yellow wire is the one you should be able to jump the battery to. You'd need to ground the battery somewhere like the firewall.

When in doubt, reference the wiring diagrams: https://www.7173mustangs.com/misc.php?page=diagrams
Thank you!  That's exactly what I needed to know.
