i was digging through the dash to swap my heater only box with a heat/ac unit from a 91. i found a relay? its not on any diagram for my year of truck that i can find. The questions are what is it and do i need it? the truck runs without it. it has only 4 wires and what looks like a battery backup?

I don't have a maintenance light. The PO put a gauge kit where the info center would normally be. So it should be safe to remove when I get to rewiring?

should be fine to remove. the maintenance require light should be in with the gauges. i used it on my 81 as a reminder when my electric fans were on.
