I just bought a pair of auto meter Pro-Comp Ultra Lite Electric oil pressure/water tep for my '93 5.0 LX. Does any body have any pics or diagrams on how to hook these things up. Anything would help.
If you feel like searching, you will find volumes (I say that not to be a turd, but if you are itching to get these in, you can start sooner).
Srothfuss did a pretty nice write up on installing some gauges a while back. A search of threads he started could be helpful.
WHere are you mounting the gauges? That often determines where one taps power.
For lighting, you can tap into fuse 13 or a dimmed display (for the HVAC, etc).
For OP sending unit, you can make a Tee fitting and keep the stocker. Stock pipe is 1/4" NPT and most aftermarket stuff is 1/8" NPT.
For water temp, I would relocate the stock sender somewhere else (rear of the lower intake, t-stat housing, etc) and put the AM gauge's sender in the stock location (that location is hard to beat).
