Where do I connect them to in the engine wiring harness? Question: If these capped wires in the engine are the same wires that are in the console, There are 2 wires coming out of each engine sensor and plugged into connectors. I have not check yet if these wires are the same wires I found 2 capped wires on the starboard side of theĮngine (see attachments) 1 tan and 1 blue. Gauges are hooked up but are not responding. I 'assumed' that these sender wires were connected to the engine sensors! So I thought this would be a good time to install these gauges to monitor engine temp and oil pressure! On the engine starboard side, near the oil filter. The engine has a water temp sensor 885342002 and an oil pressure sensor 897447002 installed I did not have a water temperature gauge or an oil pressure gauge, so they left them unconnected. When I had this engine installed on my boat, new by a Mercury Dealer, That were not connected in my steering console.
In the process of troubleshooting the overheating problem I discovered 2 sender wires
Had a overheating problem on my 2014 Mercury 90hp 4 stroke outboard that I diagnosed as a Question: Wiring connections for newly added water temp and oil pressure gauges.
