1989 Dodge Truck put a carb on

If you want to use points and condenser, you have to go back to 71 and older. If I recall, 72 us when they went to all electronic ignitions in their vehicles.

Please understand, normally we only recommend direct fit parts and OEM type repairs. As far as the points and condenser, no, a crank sensor isn't going to work. Individual cylinder ignition is sparked by the points. The concept of a crank sensor didn't exist then. Please don't take offense because I have no idea what you knowledge level is, but what you are trying to do isn't an easy thing. The entire ignition system will need rewired. The ignition switch itself is going to need changed. Plus, you will need to run power through a ballast resister to drop voltage to around 9 volts to the points and when in the crank position, it will bypass the ballast and provide a full 12v to the ignition on startup. If you run 12v all the time, you will be replacing points every week.

Here is what I suggest. Find an old chilton's manual for. Something like a 1968 Dodge truck. It should provide a schematic for the ignition system. Most parts stores can get them for you or will have them. If they don't, you can order them via a book store like Barns and Nobel.

As far as the fuel pump, I don't like running it to a switch. In the event of an accident, the pump will continue running and that can be dangerous.

Let me know how things work out for you. Most likely, you are going to need to fabricate a new wiring harness.

You got that right. I have an 87 Jeep and can never find used parts. It's getting bad because even the aftermarket parts are getting hard to find. However, I found a salvage yard in California that always has what I need.
