Ok, well i guess to start out with the car is a 92 CX that i picked up cheap with a locked up motor. I ordered an LS motor from a local shop. When it got here it was an OBD2 motor instead of the OBD1 i thought i was getting. I didn't want to wait, so i went ahead and took it home. Well now the motor is in the car and i have 3 extra plugs. 2 of them are right next to the Vehicle Speed Sensor. One is a 3 pin plug with 2 wires in it and the other is a 2 pin plug with 2 wires in it. The other plug is up kind of close the the slave cylinder. It's also a 2 pin plug (its not the reverse sensor, it's already plugged in). When i looked at where the engine and trans bolt together, they don't look like they belong together. One looks slightly cleaner/ lighter color than the other. Is it a possibility that it's an automatic long block with a manual tranny slapped on there? I haven't gotten everything finished yet on the swap to start it and see what CEL's it has, but just wondering if anyone could shed any light on this. Also, just wondering what i need to do with the vaccum lines that ran to my TB on my old motor since the new LS does not have any place for them. It looks like they go to the charcoal canister for emissions. Thanks in advance.
