Oil sender installation

If you wanted to be crafty you could wire it up to the fuse block and then have a singular fuse for it. I chose the easy way. While I was there behind the radio I tapped into the radio light wire so that I had light to the gauge when I turned the lights on, and the radio ground wire.

With these three wires in hand all I needed to do was attach them to the gauge. There is a positive terminal, a negative terminal, and the sender terminal. The hole in the gauge is for the light. The black wire from the light I connected this to the negative terminal on the gauge along with the ground wire from the radio.

I then attached the positive wire to the positive terminal on the gauge and crimped the light wire to the white wire from the light. With a fair size length of wire I attached it to the sender terminal on the gauge.

Now with every thing attached to the gauge it can be installed with the supplied U bracket and hard ware. If you want the pro look take some wire loom and wrap it around the wires to make a nice looking harness. The last wire to hook up is the sender wire.

Find a nice place to route the wire through the fire wall. Right next to the main harness is a good spot. If you have to drill a hole then make sure you have a grommet in there to protect the wire from the exposed metal. Using zip ties where possible, run the wire to your new sending unit.

Now that the gauge is installed it is now time to hook the battery back up and fire up the engine to see if it is working. Also check to see that the light comes on with the light switch. If it is working then it should read about PSI at idle. Take the truck for a run around the block to get all the air out of the sender. At a cruising speed I found mine to jump to 60 PSI. You can now sit back and relax knowing that your oil pressure is being monitored with a more accurate number rather than L or H.

Aftermarket, piggy back, oil sender installation. Next, obtain a stainless steel braided hose kit. Either will work fine. If you choose not to use stainless braided hose, and you want to use something non-conductive such as nylon pressure tubing , just make sure to install a ground wire to the mounting bracket as mentioned earlier, which will transfer ground to the sender body. The sender may be too large for the space allowed where the oil pressure port is located.

The idea of having two senders hanging off of one small port does not sound like such a good idea. You are after a clean look, and would prefer to simply have it elsewhere.

This could also solve premature failure issues by remotely mounting the sender off of the engine. Thread the stainless line on the above installed adapter, tighten the line, and route it to your new sender mounting location.
