Help. Round plug into a square hole.

[digdug002000]

Hi. Just had the engine on my 1993 Explorer swapped. Donor engine came from a 1991. Problem is it has a round plug that needs to go into a square plug-in. Currently unplugged. Think this is why my coolant temp gauge and oil pressure gauge not working. And I would like them too.

Any thoughts?

Swap the sensors from old motor.....

But 91&93 should have all the same sensors..you sure your trying to plug them into the right thing?? Especially the oil pressure one..I know they are all the same and pretty sure the water temp is also. .

What he is referring to, is the engine harness. My 92 had a square plug, and my 91 donor had a round plug for the engine harness.

I had to swap engine harnesses. So swap harnesses from the 93 and everything should be good.

Okay Mc Cribb. The engine is already in. Is there any or an easy way to swap the engine harness now? Thanks.

Unplug it from the sensors. The hardest one to get to is the crank sensor.

It takes 20 minutes or so.

You can swap the harness without pulling the engine or intake/plenum (I think the air tube came off) At least I can't remember having to do that..

All the wires run "around" things and any places they run through they are going to a sensor so once disconnected they can be pulled backwards...

It is still a pain but doable...
