88 Dakota 3.9: installing aftermarket illuminated oil pressure & water temp gauges
I hope to install aftermarket illuminated oil pressure & water temp gauges on my 88 Dakota 3.9 in the near future. Oil sending unit is on the passenger side by the distributor, but I’m not for sure about the location of the water temp gauge sensor.
Any help & suggestions would be greatly appreciated!

Thanks RalphP! That’s what I was thinking. I should be able to install the aftermarket temp sensor there & run the capillary tube into the firewall for the gauge inside the truck.
What about the electrical connector for the oil pressure sensor?

Depends. Are you concerned about the "LOW OIL" light and the dash gauge, or not?
If you are, put a T in and feed both gauge sensors.
If you're not, don't be concerned ... LOW OIL light is a switch that opens when the pressure goes above 7 PSI, so you can leave that circuit open; the in-dash gauge will just show "0".

I'm sure there is, but without knowing what you are going to, we can't help much.
Is the new one smaller, or larger, than the old one?
If smaller, a bushing should be available at most plumbing supply stores.
If larger ... We gots problems, bossman. The end should be in the water flow; that's kind of hard if you use a larger coupler, an adapter, and a all threads nipple to make it fit.
