I replaced the head on my 93 2.3L SOHC. I put a new temp sending unit on the new head before installing it. Now as I am making all the connections, I find that the wire will not connect to the unit. Is it possible that the new unit has a different type of connection? If so, what do I do about that? I am not sure that I can get it back off since the engine is all back together, There is almost no room to get to it. I am also not sure which wire connects to it. I have one wire with a single black wire going to the connection( I am pretty sure this is the one that goes to it). But the connection on the unit takes a totally different type on connector.
Can anybody give any advise on what I should do? The car runs fine but I hate not having a way to know what the temp is incase it overheats.
Thanks
