TCI sells a kit to make the OD work in your Elky.

1. Remove the pipe plug from the fourth gear pressure port. If you have a 200, the plug is located on the right side of the transmission, to the left of the servo cover at about the 7:30 position. You may need an adapter for this; some transmissions have different size plugs. Or if you have a tight fit, you may need to use a ninety-degree elbow.

2. Install apressure switch that you can purchase at CarQuest. The part number is CPS 80466 (I paid $27.25 for it). If you don't have a CarQuest, you can purchase the switch from Stewart Warner as part number 76054.

3. On the left side of both transmissions behind the shifter rod, is a switch that has two (sometimes three) terminals on it. If at all possible, get the factory wiring harness that plugs into this switch from a donor car. The front terminal (terminal towards the front of the car of the factory wiring harness) should be either red, or brown with a black tracer stripe. That wire should be routed to either terminal of the switch you just installed on the right side of the transmission. The next wire of the factory harness should be either purple or black. This wire should go to a GOOD grounding source. A third wire may be present on the factory harness. That wire was used for a high gear signal to the computer. Cut or tape that wire off, it is not used.

4. Run a wire from a twenty amp fused source, that is hot when the ignition switch is in the run position only, to the remaining terminal on the switch you installed.

5. Enjoy!
