The other plug, the one you removed for the temp gauge... Would I get pressure from there as well? Would it be the same reading? I know you didn't do it that way, so I'm just asking in case you know.

The reason I ask is because of the removal of the oem pressure sensor. What effect will this have to the dash light, and the ecu or anything related for that matter? Will I have the dashlight on all the time?

Would you consider wise to add a "T" to maintain both oem and aftermarket gauge pressure sender? I'm not sure how a "T" screwed there would react to vibration, so I'm scared it might crack or break.
Hey Man,

You could use the back hole for the oil pressure but the way the port is in the block it's not the best place to grab a signal. I use t for temp just because it's a stable location without too much fluctuation.
The stock oil pressure signal has no effect on the ecu and is more used as an idiot light in the dash. Disconnecting it will NOT give you a light in the dash. There it no need to "T" off at all since it it a completely different type of electric signal and you will be able to see a pressure drop a lot faster with your gauge than the stock warning light can ever do.

Cheers,

- Jason
