Hey I’ve got a 91 RT4WD with a ZC JDM motor that the previous owner swapped. My coolant temp doesn’t read on the dash anymore and I found some disconnected wires coming out of the harness. There’s a green/black and two yellow wires with only one connecting yellow wire. The wires coming from the two pin connector to the temp sensor are both black and seem connected. I’m wondering if there’s other sensors somewhere? I know there’s one above the fuel filter and that one is connected properly. I’m definitely no wiring guru and think the guy who put this together didn’t do it all the way properly.
if you have any wisdom or need more photos let me know and thanks in advance!

I know these wires are not properly connected they were just loose so I was testing to see if connecting them did anything, not finalized
