Where to plumb mechanical oil and temp gauges in 4.0l 1990

where can I plumb in some aftermarket gauges to my 1990 4.0L

when i plumbed my 3.0l i used 2 brass tees inline with the stock sensors, then i screwed my temp sensor and my oil pressure line into them. i believe 1 was 1/4 NPT and the other was 1/8 NPT. the only hard part about the install was getting the mechanical temp sensor probe into the tee because of its length and still making sure the stock sensor would screw in without interference. i eventually went from the cheap set of sunpros i originally installed to a set of electric autometer gauges with a manual oil pressure gauge (i used a braided ss hose to run my oil though instead of the plastic or copper tube because i got sick of screwing with the compression ferrules after having to remove the engine and gauges a few times). the work involved is definately worth it as you have no idea how "dumb" the stock gauges are until you compare them to mechanical ones.
