Hello, I just bought a 93 Del Sol 1.6L so I am new and just joined.

I plan on restoring this car while parts are still available haha, but today I noticed the carpet on the passenger side was loose. I pulled it back and found the ECU, not bolted to its mount.

That didn't surprise me, but then I saw two different wire connectors not hooked up to anything... there is a green little box they fit in but no wires leading from it.

Any idea what these may be for? I can't find anything online about them. Thanks!

 

Those plugs DO NOT connect to the ECU.

 

The 2-pin plug is your MIL/Service Connector... jumping/shorting it will allow one to set the distributor timing AND make the CEL on the dash flash with any stored trouble codes. The 3-pin plug is the OBD-1 data port and connects to a specialized converter to allow real time data to be examined while the engine is running. They fit inside the green rubber holder when not in use... so NO, they are not normally plugged into anything.

 

Oh sweet thank you that's way informative, I'll just put them in that green holder and let em be!
