Before buying another 74 harness, there is one thing you need to know,that is the first year that they came out with an interlocking seat belt module. It an ivory colored box with 2 plugs, next to fuse box, in wiring harness, if yours is bad ,or someone tried cutting it out without rewiring, you lose 11 different functions, from turn signals,flashers,parking lights,dash lights, radio, glove box light and some i don't remember. On ebay they sell those modules for around $125, if you see a green one, its from Canada, they didn't have mandatory seat belt laws, so the green one is a bypass module, and if you see an orange one, its from cars that went to venzeula , it also bypasses,Mopar realized these modules were a problem and quit putting them on in 1975,also on the fender well next to where the washer reservoir there is a reset button with 3 yellow wires , one has a black tracer on the wire that you have to rewire around, if you look at the gauge cluster on the round connector, you will see double wires going to cluster to each pin. I had one on my 74 duster ,and the module was white with corrosion and i worked for 3 months trying to remove module and get car to start, no luck, finally went to junk yard ,found a 1971 dart, pulled all wiring under hood and under dash, $60, put it on car ,had a few connectors like to heater that i had to replace ,but it started ok,you will have to download a 74 schematic, i found a few changes in pin arrangement ,and downloaded the 71 schematic to rewire. All that being said, if your module is good you can just unplug the connector under the seat , passenger side as well, and rewire the reset button on fender well ,then you can get by, but unplug the ivory module and look at the pins to see if they are corroded, if so, good luck, hope this helps you
