Put a carb in a '91 Dakota?

Since we don't need emissions checked on '91 vehicles here, I was

You need an intake manifold and carburetor as well as a distributor to make the engine run. Retrofit the older magnetic pickup distributor and wiring for this. I presume you can get the fuel pump to operate without the computer? If not, you can retrofit a mechanical unit, but, it's a big retrofit, IIRC, it requires a specific camshaft and an eccentric. I believe these are Dakota specific parts?

The overdrive and lockup for the transmission can be controlled with switches mounted within your reach in the cab.

As to the operation of the rest of the truck sans computer, I don't know.

Like BIR said, you can control your tranny's limited electronic functions (TCC lockup, and OD engagement) with some sensors and switches. See this website for more information:

What could a harness cost?

I hadn't checked myself yet, but many parts for a '91 are impossible to find, they made changes before & after that year. I couldn't get a belt tensioner/idler pully 5 years ago - a mechanic rigged one up from parts from 2 other models. The only way I would want the truck, is with a carb & ignition system I can fix myself.

Great stuff there, thanks!
