That sounds like a good idea. Just might need to relocate some of the Merc wiring and such as that area is jam packed at the moment.

So now I check that location a little more detailed to see if I can get in there with the pressure sensor. What I found was in the bunch of wires, coil and other things in the location is that theres a blue wire hooked to a sensor in that port. So I need to know what its for and what I can do about it. Anyone know? Is that possibly for the low oil pressure alarm??

If its a Dark Blue wire then its the analog oil pressure sender wire

Can I put a t in this location and put that along with the oil temp gauge and everything work fine?

Yes, that is an easy way to do it
