Distributor rear electrical connectors?

[justbob40]

Hi,
I'm new to this forum, wow what a bunch of nice rides!

I just dropped a re-built 350 in an 87 blazer, though the motor was out of the truck when I purchased it so I'm kind of running blind on the re-install. From what I can see, the wire harness has only (1) electrical connector on it that goes into the back of the distributor, though the distributor has (2) connectors on it. Do I only hook up the one (4 pin) that fits the connector located on the passenger side and the other connector (on the driver side of the distributor) stays/ remains vacant? Any help would be greatly appreciated.
Thanks,
Bob

I am assuming being an 87, it is TBI.

If so. 2 wires to distributor. 3 to the TPS. 4 to the fuel flow sensor thing on the TB. 2 to each injector then there is the smog junk.

A picture of the wires in question will help. Pay for the membership. It will be worth every penny.
