Rear Speaker connectors

[oneof52]

Hello, hoping someone can shed some light. On my 70 Cuda dash, tried to locate the male rear speaker connection. I found the inline 4 wires with correct color wire, but not the same connector. Does anyone have any info on this molex type connector? The dash wiring is also missing the grey oil pressure wire for the Rallye Dashes

Is it possible you have the standard gauge wiring harness connected to a rally dash instrument cluster? That seems a common complaint for those upgrading their dashes to the rallye.

When you say "not the same connector" as... what? the speaker wiring harness from the trunk coming forward?

I have a 5 speaker system with the fader and crossover. I need to connect the rear speaker to the connector that goes from the dash harness to the rear. This is the harness that is being sold, not the same connector.

I'm not finding the data among my notes, but I seem to recall the flat four-bullet connector came with early 1970 cards, and the four-spade connector on later 1970 through 1974 cars. Maybe it's the other way around. I'm still looking among my notes.

The 1970 Plymouth Barracuda factory service manual show a stacked connector

While the 1972 factory service manual shows a flat connector.

From memory, this connector doesn't show. Consider making a small conversion harness, if you don't want to cut and alter either harness.

This might help.
The wiring is the same for the most part.some connectors are different year to year.

copy-pasta might help. though he did say it was a Barracuda.

When I I stalled a Kenwood stereo in my Challenger years ago, I made short conversion harnesses between the stereo and dash harness and between the rear speakers and factory harness. Front speakers are in the door panels from a previous owner. Sigh! But I'm not too big on originality in some cases. Especially since it was my only transportation for fifteen years. But I knew not to chop up what I could prevent. Of course now they make all new harnesses including custom ones if you want.

make a short jumper between the connectors. A spade terminal will fit over the male terminals,heat shrink and do the same for the bullet connectors.

Making a small conversion harness is a great idea. Well done.

This is really helpful. I also found out that the molex pin type connectors (shown just above) were used until mid 1970, after which they switched to the square type.
