gauge ?s

[aarolar]

Good question and on the subject does any one know the drill and tap size for the temp sensor? I belive its 3/8 npt but I am not sure

[NITROUS]

Tap the block off plate above the oil filter to 1/8" NPT and install the oil pressure switch there. There should be enough wire in the harness just take the tape off of it. You can get a temp sensor adapter from Welcome to Street and Performance

Hope this helps.

so you do need to run both oil pressure sensors?

[NITROUS]

Yes, one runs to the pcm and the other from your old engine will go to your gauges. this is the same on the temp and oil pressure.

ok seems red told me I only need one, I broke the one off the 5.3 and he told me to just drill and tap the broken piece for the one off my 5.7

[NITROUS]

You can still do that if you wish, it will work either way.

[RedHeartbeat]

If your sensor is 3/8 NPT then you'll need a 9/16" drill before tapping. That one would not fit the block off plate above the filter without some kind of reducer.

You can still do that if you wish, it will work either way.

How can I do it either way I though I had to have both on up to and one at the blockoff plate?
