Hooking up the electric choke.

Your best bet would be the red throttle position wire, if it still exists in your harness. Otherwise, tap off the pink wire from the coil.

You can't hook just any electric choke to the alternator. Electric chokes designed for connection to the alternator are designed to operate on 7 or 9 volts, I forget which at the moment. Other electric chokes are designed to operate on 12 volts. So where you source power to an electric choke is dependent upon how the manufacturer designed it.

The wire originally intended for the throttle solenoid is a popular source for 12 volt chokes, I personally prefer supplying the choke via addition of a relay and a fuse, just like the relay & fuse I prefer for the ignition.

Both Holley and Edelbrock do not recommend using the 12v power side of the coil to power the choke. This is specially true if you are using an MSd or similar box. I used the switched power supplying 12v to the reverse light switch by tapping into it at the main connector to the rear wiring harness.

As a matter of interest for my echoke I tapped of the Pink wire before the ballast resister for full 12volts. So essentially the + side of the coil without the resistance. I understand ideally you do not want to pull anymore through the ignition switch than needed but what other problems could this create.

I've seen many of those pink wires burn off, my car included, through the harness. So I wouldn't chance it. And, at the very least, the supply power to the electric choke needs to be from a fused source or you must install an inline fuse. The ignition wire is not fused.
Good luck with that.

I have the interior totally out of my car because the pink wire burned all the way to the coil. Got hot enough to stick to the insulation on a couple of other wires.

WARNING: if you hook an electric choke wire (or anything else) to the hot wire on the coil, you have just installed a REV-LIMITER! The extra device- whatever it is- will pull needed amperage from the coil and your mighty 351-C will now only rev to MAYBE 3500 rpms. Find another place to wire accessories.

Ok, thanks for the replies, time to move that choke wire.

It's too bad somebody doesn't address the choke connection issue properly, I wonder what's available to resolve the choke wire?

Damn, I wish I knew about your EIS Kit 6-8 months ago when I purchased my Mallory ignition controller and tach adapter.

Looks like you have a great product there John!

Garth,

You could always sell the Mallory and buy Jon's EIS.

I have had a good look at that Pantera Electronics EIS and it seems to be amazing. It makes me wonder why the big name manufacturers haven't done something like this. And the price is no more expensive than a standard cdi system with 10 more features that bring it into the 21st century.

Incidentally I fitted that relay to the ignition for the coil, choke and electronic distributor. Now the damn thing won't shut down the engine when I switch off the ignition. I have to remove the ignition wire from the relay to cut the power to the coil etc. Something to do with feedback from the alternator or some such? Anyway another relatively simple task made difficult. Got to love cars.

"Wonder why the big name manufactures haven't done something like this"
Just because they are big does not mean they are clever and agile or know what there customers need.
This is from Wikipedia about MSD:
"In 2004 the original owner of the company, Jack Priegel, sold the company to a private investing firm when he decided to retire. Gryphon Investors announced that it would be purchasing the company and brought in Dan Gresham as the CEO. Since that time MSD has been sold and changed management again."

The announcement at the link below, I didn't see anything about focusing on good customer service.

Pantera-Electronics has been around for a lot longer than six months.

I would think some of you guys...some, should have discovered electricity by now? You should try it. It's an amazing thing?

That is something I think I am leaning about the world in general. I hear much talk about MSD and how wonderful their stuff is but they still use mechanical advance when Crane Cams, who isn't even a dedicated ignition manufacturer has electronically adjustable advance on their distributors. They are still using technology that is decades, the 6A ignition box is still the size of an old brick mobile phone when phones today are a tenth of the size they used to be and do one hundred times as much. I cannot for the life of me figure out why a distributor needs to be so large and tall in this day and age either. In a world where everything is getting smaller and more powerful some things haven't changed and it just does not make sense.

We are getting way off subject here but anyway.

Why? Demand is what drives them. Demand for technological advances in personal electronic devices like cellphones, now called smartphones, is such that designed obsolescence is like 6 months these days (check the model of your kid's iPhone, the next release is the 5S). For the automotive industry, it's more like every decade or more. The large automotive aftermarket manufacturers focus on demand, where the money is. Technology advances with more cross-platform applications the better. I remember Edelbrock listed their Torker 351C intake fitting a 'Ford' Pantera but, oh by they way, on their note it says the intake/carb will not fit under the engine screen. Car specific? no, engine specific? yes. I dont think they would have made it if it only fit one car. Smaller or niche markets, are usually taken up by the smaller manufacturers so support our vendors.
