I just got my new HEI distributor from Jegs. I have a few questions with the connections. I have a '74 Malibu with points. So on that distributor there was only a black wire coming out of it. On the new unit, there is a black /red/ brown wire coming off of the base of the distributor.

On the old coil, there was the black from the distributor base. on the positive from the old coil there were 3 leads, one going to a silver little module on the bracket, a second which was yellow and a 3rd which if memory serves was brown.

Now I have been told that I will need to run a constant HOT to the distibutor, aside from that, what else am I in for and where should these wires be routed to?

On the HEI cap/cover there are some connectors tagged. " C- , Gnd , B+ , Tach , Bat ,

Now I do not have a tach on my car. I assume that the added HOT goes to the BAT terminal.

One other thing, since I am going from points to HEI, I don't have a factory type plug/harness that goes to the Cap/coil harness. Should I look for one or just use flat connectors and connect them individually ?

Any help is greatly appreciated.
for the record
1974 chevy malibu
350 4bbl w/ a/c
without a tach.

The plug that comes out of the base of the dist. plugs into the cap.

Then all you have to do is run a 12 volt switched wire to the + or where it say Batt.

If you hook a Tach later. the Green tach wire will plug where it say tach.

That easy. You can use a regular female blade connector ,but I would suggest going to the parts store and getting the correct one. It will snap in place.
Later,Glen

You say the wires coming out of the base of distributor get plugged into the cap.
The plug does not just "Plug" in right? Because this is a rectangular plug with the 3 leads. So I assume I have to cut the plug and wire them in?
If so, which terminals do they go to?

This here ain't rocket science. Plug the three prong connector from the dist body into the cap, it only goes in ONE way, cannot mess it up, no cutting needed.

Next, from fuse box term marked IGN or IGNITION, run a 12 guage wire through the firewall to the B term on the cap, done.

Note: almost ALL IGN fuse box terminals on GM vehicles supply a clean 12 volts, both start and run key positions. If yours doesn't supply this power at start position, run wire from the R terminal on ther starter solenoid to the B on the cap, AND the IGN term, system should work fine.

Yeah, you guys are right, When I got the distributor, I only really glanced at the connector with the 3 leads and thought it was much larger than it actually was. I don't know what I was thinking, I just had a distorted picture in my head. Anyway, it plugged right in.
Thank God it is not rocket science or I would be screwed.
Thanks again.....

Its all good man.

I know it just blows your mind that a car company could engineer something simple that works so well.

Don't feel bad, I have to work on all this ignition stuff while wearing my special anti-alien abduction, anti-scrambled egg tin foil hat.
