I have an 04 TJ with a L59 out of a 2004 suburban that I'm swapping. I'm keeping factory gauges.

I plan to use an adapter on the stock GM oil pressure sensor location to install the Jeep sending unit. I need to find the correct adapter but can't figure out thread pitch/count for both GM hole and Jeep sensor. Any help on which adapter to use would be amazing. Here is the Jeep Oil Pressure Switch I plan to buy.

Also, I plan to drill and tap the driver side block to install Jeep temp sensor, any help on finding the right tap size for the Jeep sensor to fit in the block? Here is the Coolant Temp Sensor I plan to buy.

Thanks in advance for any help.

Ok, after talking with Novak, here's the plan.

Use this on the head to adapt for the temp sensor, it's a 3/8 female.

For oil pressure, I plan to use this adapter.

Now I don't have to drill or tap any new locations to retain stock gauges and the GM computer retains all stock sensors.

Thanks, good point. I am planning to retain the TJ PCM, Novak did the rewire on the GM harness and I believe I have to connect a few wires to run to the Jeep PCM. One day I'll finish this and upload all my videos to Youtube.
