Reply to "No Back up lights"

...OK here's the last word I have to help you! I studied the wire schematics that work exact with My '74. 1) A (aprox.) 10 gage RED wire comes off the Positive terminal of the Battery, goes through the front bulkhead to the AMP gauge. 2) From the AMP guage comes a BLACK wire that splits off into 4 PINK wires. Don't get confused!! The only PINK wire You have to be concerned with, is the One that terminates at the Ignition Switch. Yes! This is supplying The Ignition Switch with 12 Volts DC. 3) From the Ignition Switch, when at the 'RUN' position, comes a RED wire that supplys power to FUSE #11 at THAT point there is a 'JUMPER' (brass bar) that also SHARES this 12 Volts with FUSE #12, this IS the fuse Your concerned with! 4) Off the other end of FUSE #12, comes a GREEN wire that travels straight back through the FIREWALL on the Passenger side, and near the wheelwell; goes through a Plastic 'Multi Contact' PLUG, (THIS may be A source of Your Problem. As corrosion here is inevitable!). That GREEN wire, after the Plug Connection, Continues GREEN all the way to the ZF Transaxle To the 'Back-Up Light' SWITCH!! 5) There should be 12 Volts here when the Key is 'ON'. 6) From that same switch, comes a WHITE Wire, to the 'HOT' contact of BOTH B.U. Light Sockets. (The wire was split on the drivers side). 7) From BOTH sockets goes a BLACK wire directly to ground at the STUD in the center of the Rear Tail Bulkhead. In fact ALL the BLACK wires in the 'Rear Wire Bundle' go to ground. That completes the curcuit; PROVIDED Your Battery is Grounded to the chassis in the first place!!! I asked you if you 'Shorted' the Back-Up switch to Test it as being Good! I have not heard an answer. This gives You a couple more things to check out, and is all the help I have for you. Check for 12 Volts at that 'multi contact' PLUG, and AT the BACK-UP SWITCH. Make certain that the GROUNDS 'IN' Light BUCKETS are GROUNDED, as Larry F. pointed out. Lets get these Lights fixed!! And then get back to us!...
