So I realized my 1979 C3 is literally missing the tachometer filter. simply not there. So I figured it'd be a good thing to buy one, not a big deal. However, the filters I've seen online don't have the plastic electrical connector ends to attach to the other stuff. Here it's just the wire and bare metal. Picture 1 is the filter from corvette mods. Picture 2 is the plastic electrical connectors I'm looking for (circled in red).
Can y'all help me find those plastic electrical connectors?
The F/M HEI Tach end is GM 8917052
I cant find a part number for the male side?
I have looked through 75-79 electrical line diagrams and NONE show a tach filter...
A standard Male/female crimp connector set will work for that end.
The connector on the left is the male housing I have no number for, the right side is the F/M 8917052 housing.

These are usually sold in sets, power side and tach side. Just remove the green wire and use the supplied tach filter wire and crimp connector for the new housing.
The replacement filters have new metal connectors...but no plastic housings. They assume that you have the plastic housings, already. In truth, it doesn't matter what kind of [single wire] connectors you use to connect it into the system. Use whatever you have available or get a matched pair of connectors at any car parts store. If you want the 'original' style connectors, you might search e-bay for Packard connectors or find what you need at a local Corvette parts swap meet.
There are plastic connector housings that 'look' like Packard connectors in the aftermarket. But, they won't match up well with real Packard connectors. You will likely have to get both male and female plastic aftermarket housings and use both to make everything connect well.
