Don't know if they make a plug-in connector specifically for this. I made my own. You can do it on the cheap just using female spade connectors, but they can be tough to line up on the male ends on the underside of the HEI cap (tough to see if you're catching the connector or just wedging it in next to it).

Another alternative is to buy 2 large cap HEI-specific connectors with pigtails (one for the BATT/12V+ connection, the other for the TACH connection). Those pigtails should be available from any good auto parts store if you look through their specialty electrical connectors catalog. Or stop by your local junkyard and clip the connectors off an older GM HEI-equipped car (anything 1986 or older should use an old large-cap HEI). They were used on many GM engines of that vintage, not just Chevys.

Original Pink wire (larger 10 Ga. wire) is for the BATT/12V+ connection, original White wire (smaller 14 Ga. wire) is for the TACH connection.

Accel makes a one-piece HEI connector.

awsome thanks guys!
i wonder why none of the qriteups or stickys mention this?

Damon

Probably because we didn't know about it! Thanks for the info, Pre-Tuner.

Factory terminals are individual ones for the power and tach. That's the first one I've seen with both of them molded in one piece.

i found a connector on summit that will plug into both the tach and the power side.
For now I got a female conector just stuck up in there for the power.
ACC-170072 Thats the part number incase anyone else searches and finds this post.

Thanks

The EFI to carb tech article (linked in the "welcome to the carburetor forum" sticky):

"The next thing you'll want to do is drop in the distributor. There are basically 3 options for this, junkyard, remanufactured, or an aftermarket. GM used the one you need from 74 to around 83 I believe. I used an Accel aftermarket one. It needs to be complete with the Firebird or Camaro ignition module, wiring harness, cap, rotor, and coil. Drop it in the engine, being sure to get it on the same tooth as your old distributor. The old coil has 2 wires going to it, you will need to connect these wires to the connectors on the new coil. If you can find the proper plug assembly in a store or junkyard for it then great, I simply used two crimp on female spade connectors to clip them onto the new coil.It will have only 2 connectors to go to, the red/pink wire goes to the one labeled BATT, and black wire goes to the connector labeled TACH."

As Damon noted, the tach wire is white, not black. I'll see if we can get that corrected.
