5.9 Tc2000 check engine light

Hey yíall, I have a 1993 bluebird tc2000 with a Cummins 5.9 in it.. The vehicle maintenance light came on recently and I have not been able to find any information on how to pull any codes out of it.. Iíve looked all over for an obd1 port to connect to with no success.. Not sure if thereís a thread that covers this already but any information or a point in the right direction would be greatly appreciated!!
Thanks!!

I am pretty sure that is a mechanical 6bt Cummins with a p pump. No obd port no computer Is it possibly the low coolant light. The sensor is located in the front top of the radiator. Or is their an actual low coolant light making my guess a moot point.

Okay cool, I had a feeling that was the case for the mechanical 12v. It could be something with the coolant sensor, there is no coolant light though.. Iíll start by cleaning and possibly replacing that sensor as well as clean up the connections on my ground connections from the block to the chassis
Thanks!

Check for a bad ground for the dash unit. It may mean taking it apart. Be gentle. Take pictures to identify wiring, and maybe even label wires with tape.

Could be the gauges themselves, they all act independently.. when itís raining I can tap on the tachometer and it will start working for a moment but other gauges seem more random.. itís going to take some sorting out
