190e wiring question
 

Hi,
I have a 93 190e 2.3 4cyl. There is wire bunch that comes from the computer. One wire goes to the water temp sensor, one goes to the AFM pot, one goes to the engine temp sensor, one gets grounded on top of the intake manifold #1 and there is one more that gets grounded below the intake cylinder #1 right below the valve cover. Is that correct. I am kinda suspicious about this one. Please help. Thanks
