90-93 Link Ecu IAT and knock sensor issue HELP
I have a Link MK1 that was upgraded to run, wideband, knock sensor, and intake air temp sensor. I was hoping someone may have a picture of an upgraded MK1 ecu on both sides. So, I can compare and make sure mine was upgraded correctly. I am not getting a reading from the knock sensor or the iat. I have moved the ground on the IAT sensor to a few different places. Any suggestions or help would be appreciated.

here are a few pics of the upgrade.
back of the ecu
front of the ecu
this is the wire that I jumped to in the diagnostic connector from the Map harness which carries the signal from the knock sensor thru the Map sensor. I was hoping someone could verify that the wire is in the correct spot. I verified that it correlates with the pin in the ecu marked for knock.
This is the wire that is hooked up to the IAT sensor.
This is one of the spots I attempted to ground the IAT sensor to.
Here is the other spot I grounded the IAT too, thinking I had a bad ground.
Well wiring and electronics are not my strong point so I was helping someone might be able to see where I obviously made a mistake. I am open to ideas and know most of the guys on here know a lot more than I do.
