Ballast Resistor on 73 D-Jet

All you have to go is clip the wire of the CHT, splice in a 270 ohm resistor and thats it right?

Curses, foiled again

Just put the proper connectors on the resistor so it fits between the plastic connector and the CHT. If you use the cheapie ones from Radio Shack, cover the whole thing with shrink wrap tubing and its good to go.

Here is what the OEM resistor looks like:

What's this for? Is it to keep from changing to a NEW CHT?

No, the 73 2.0L engine was put together is such a hurry that Bosch didn't have time to build/develope a 2.0L ECU. So they used the 1.7 ECU and to richen the idle mix with the CHT they used a resistor. That's why you must run the right CHT and ballast resistor on a 73 2.0L to get the idle mix correct.
