Truck listed above is an All Terrain. Pulled out A/C relay and didn't realize there were two ways it could go until I saw the diagram on side of it by then I had forgotten how it was and the fuse box does have the numbers on it or I can't find any. Please help. Thanks and Godbless!

Hi,

The relay should only fit one way. If you look at the attached pic below, I highlighted its location. That is the under hood fuse/relay box on the left side of the engine compartment

Also, here is a link that explains how to test a relay. I thought it may be helpful.

Let me know if this helps.

Take care,
Joe
