OK the dodge has the relays on rubber grommets and the Ford in my garage the relays are right on the fender with sheet metal screws. For my Dogde do I have to use the rubber grommets so it is not grounded?? The relays I bought look just like in the pic you posted.

Your Lincoln's relay is 12V+ switched, so it's case-grounded; the new F**d relay is for your Ram's negative (ground) switched grid heater control circuit, so the case must not be grounded - reuse the grommets for peace of mind, but the relay should already be non case-grounded if it's like the one in the photo.

Take an ohm meter to the relay, as long as there is no conductivity inbetween the mounting bracket and either of the small terminals it doesn't matter if you use the grommets or not.

Refresh my memory about conductivity/ohms. On the dodge relay I can touch the braket to any of the post and no readings, on the ford relay the bracket to one of the small posts is 3.9 ohms. I think I did the measurements right. So far I have not done anything to the truck, because I got to the oint of wondering what about the rubber grommets and quit.

It sounds like the relay you have is grounded.
You will have to make sure that when mounting the relays that the bracket doesn't touch any metal parts of the truck.
Use the grommets.

If the relay is mounted on the gromments but use metal screws won't the head of the screw contact the metal base AND the truck to create a connection, WHICH YOU DON'T WANT?

Well I think I am just going to return the Furd parts and fork over the cash for a new Dodge relay. I was going to do this cheap but it won't be cheap if I burn something down because the parts store doesn't have unobtanium alloy screws.

to use the grounded f**d relays, just add a relay triggered by the computer to trigger the relay by sending 12 to the terminal & mount e'm solid. You have power at one of the large terminals. feed from it through the relay & back to the F**d relay. Trigger the small relay's coil with the computer signal.
(note, this how i would solve the probly, but, i have never done it)
