Just upgraded my 84 toronado with a new trans and engine work tore out all old emissions system and ac compressor as my state doesnt require it to test due to year of the vehicle, but dont like to see my check engine light and low coolant light on my dash. If someone could help with what wires may need to be grounded or spliced to another to have this go away would be very helpful also running frostbite 4 core radiator for cooling.

 

Coolant level sensor repair probably culprit
track it down ...fix or illiminate

 

Remove the bulb in the dash. There's more to deleting emissions equipment than hacking off the catalytic converter and removing the smog pump.

Here's a good thread:
